Oval-Cut Diamonds give a beautiful sparkle and style. It’s recommended you choose an H color to be on the safe side and Si1 clarity. Occasionally you can find an SI2 that looks great but it’s not too common. The length to width ratio is equally important to ensure you have a classic oval shape.
One must evaluate an Oval diamond closely as it’s not as simple as a round. GIA doesn’t classify cut grades for any shape other than round. You will have to analyze the stone with other criteria.
Take a look and click on this link to view an oval diamond that has the same 4 C’s but has a drastic difference in cut and look. Stone A vs Stone B You can see the shape of the diamond is the most important feature, not the traditional 4C’s.
By clicking on the diamonds, you can see the price differences. This is a perfect example of how shape/cut is valued. Another important diamond lesson is sometimes when a diamond is discounted heavily there is a reason. ALways!
Study your diamond closely or contact me to review your selection before purchase.
As mentioned above, the shape is critical in buying your oval diamond. Lets analyze the photo samples from above a little more closely. A key factor in shape is the length to width ratio.
Oval diamonds are considered ideal in the 1.35- 1.50 length to width ratio. Most sites do the calculation for you but it’s achieved by dividing the length of the diamond with the width. View the photo sample below for a detailed break down of its l/w ratio.
As you can see, even though the carat weight is the same, you gain over 1 millimeter in size by having an ideal L/W ratio. As an example, you would have to increase your carat size by over .60 to gain another 1 millimeter. Don’t go to far above the 1.50 ratio or you will have a skinny looking stone that will affect the brilliance. Also, avoid stones under the 1.35 L/W ration, it will look stubby.
This comes down to personal preference if one prefers a rounder or longer look. Here is a link to show you examples of finished rings. Use this to compare what a rounder or longer Oval Diamond looks like mounted.
OVAL DIAMOND INSPIRATION EXAMPLES
As I have stated in previous articles, the “Cut” is king and there is no exception here. Oval diamond presents a problem because GIA does not give it a cut grade. Due to the oval shapes complicated structure, there is no ideal standard. Too many variables are at play between various length, width and depth combinations, getting an ideal table and crown angle is difficult.
With that said, there is no ideal combinations so you must take this advice as a general rule of thumb. Below are guidelines to follow that leads you in the right direction.
| OVAL | EXCELLENT | VERY GOOD | GOOD |
|---|---|---|---|
| Table % | 53-63 | 52 or 64-65 | 51 or 66-68 |
| Depth % | 58-62 | 56-58 or 62-66 | 53-56 or 66-71 |
| Girdle | Very Thin - Slightly Thick | Very Thin - Slightly Thick | Very Thin - Thick |
| None | Very Small | Click Here to view Ideal Pear | Small |
| Lenght To Width Ratio | 1.35-1.50 | 1.30-1.35 or 1.50-1.55 | 1.25-1.30 or 1.55-1.60 |
A big tip in this Oval Diamond Buying Guide is understanding the bowtie effect. All Ovals will have it with degrees of variance. With a strong bowtie, You will see a dark effect sketching from the top to the bottom middle. It can be very visible or barely noticeable. You want to avoid the strong effect as it will affect the brilliance of the diamond. Feel free to reach out to me if you need any advice with a selection of yours.
Below you will see a photo example of a bad and great bowtie.
Click on the buttons to show diamond bowtie examples
The color scale by GIA starts at the letter D to Z. D represents colorless and Z means there is a very noticeable brown and yellow color. Color originates from the bottom tip of the diamond typically making it harder from the top view to see color.
It’s very difficult to see the difference between 2 neighboring color grades and generally recommend to stick to H color or better for Oval Diamonds. This is a perfect balance between quality and price and ensures that you have a diamond that radiates white. If you set your diamond in yellow or rose gold feel free to lower your diamond color to a J or K color to save money or increase carat size.
As an example, look at this J color diamond on a yellow gold ring.

There are many grades given to diamonds. Below is a chart outlines them
Most diamonds sold fall under the I1 grade and vvs1. I consider this the least important C. A diamond that is flawless and a diamond that’s an eye clean SI1 is indistinguishable to the human eye. SO WHY pay such a high premium for a flawless.
Here is an example of an incredible SI1 that is almost perfectly clean magnified online and will be eye-clean to the human eye. IS it easy for you to see a flaw?
Is it worth spending an additional $2,400 by buying This VVS1 diamond? I try my hardest to have my clients avoid overspending and using that money to upgrade carat size, color, or engagement ring. That’s money better spent where your eye can actually see a difference.
Bottom line recommendation: James Allen often provides the most value and options for my clients and is my first option when shopping for my clients.
James Allen is one of the companies that revolutionized online diamond buying. They set the standard for photography and video allowing the consumer to truly see a diamond before they purchase. They have the largest conflict-free inventory available. I believe over 300,000 diamonds which improves your chance of finding the best diamond available. They have amazing ring designs, money-back guarantees among many other factors below making them my favorite place to recommend my clients.
When I worked in the diamond business after 2006, clients always came to me with options from James Allen and honestly, I could not compete. Recently I decided to do a secret shopper video and order to show my readers what the experience is like. I was blown away by the packaging, details and custumer service. The return process was a no questions asked, easy as a push of a button breeze!
As noted, they were the first company to offer 360-degree high definition photographs to every diamond they offer. Uncertainty was the biggest issue of buying diamonds online in the past.
NOT ANYMORE! This gives the consumer the power to buy confidently. If you are looking for the best bang for your buck clarity grade, this is the ideal way to view and search. SI1\SI2 are the ideal value clarity grades. Please note that these images are so crispy, they can intimidate you. As long as the inclusion isnt massive in size and directly on the center, they are relatively safe.
BlueNile and other competitors have tried to compete with the diamond viewing technology but have fallen short. This viewing technology is imperative for clarity and needed for fancy shapes as well as they are more difficult to grade. Fancy shapes are any shape other than round. EX. Princess cut, Emerald Cut, Radiant cut, etc.
I love this section on their site. It allows my clients to view recently purchased rings which give them the ability to view carat size, shape, color and ring combinations. Once again giving you comfort in knowing what you are buying is incredible. It’s helpful that you can filter the shape, style of ring, carat size, budget, and metal type to truly narrow down your search.
For any of my readers looking for the best cut possible, James Allen has their Hearts and Arrows True Hearts Collection. Just visually stunning, at 20x magnified, the lines are sharp and show perfection when it comes to symmetry.
Seen from above, a Hearts and Arrows diamond shows an arrow pattern. When displayed on its pavilion side, the diamond presents the eye with 8 hearts with tiny ‘v’ shapes. Genuine Hearts and Arrows have these patterns visible at a single glance, indicating that the diamond has perfect optical symmetry.
These diamonds have a small premium on them but ensure the best possible cut.
I know that most of my clients see price as the main reason to buy. But these factors below should also play a role when comparing stones from different vendors. James Allen offers:
I tested this myself and it couldn’t be truer or easier. With a simple click of a button, your return is processed! They even paid for the return shipping(USA only). How awesome that there is zero risk. This is helpful when buying a lower clarity or high fluorescence stone. Great to know you can always buy and if unsatisfied it’s an easy upgrade or return away.
They are always there if you need a hand with product knowledge or technical issues.
You never have to worry as they offer shipping to the US and around the globe. Every shipment is insured giving the buyer peace of mind.
I created a video for my readers to see first hand the experience, hope you enjoy it.
I have shopped many years using James Allen’s website and can say with certainty that its the most well rounded, value and selection site for online diamond shopping today. I know this site is written with so much healful information. But please reach out to me and I will help you navigate the site and help you narrow down a selection.

Who This Article Is For
This article is made to help my readers gain clarity and confidence in their purchase. Whether its buying a loose diamond or a set engagement ring, you will learn how to choose with confidence. Get ready to save money as well by avoiding unnecessary overspending. Buying a diamond can be tricky. And walking into a jewelry store with no education can be costly. Follow along with my Diamond Buying Guide and learn How To Buy Diamonds with confidence.
The first rule of this Diamond Buying Guide. Let’s get rid of the old rule of 2 months of salary. No rule applies to everyone and their situation. This is a symbol of love and commitment not going above your means. With that said, its important to know your significant other expectations. Do they prefer dainty like this classic .96 engagement ring solitaire ring? Or do they like more flair and dazzle like this 1.54 carat on a stunning Cambridge Halo Platinum Ring? But learning you can adjust your search with small changes. As a start get a baseline.
My advice, compare pricing using these two top vendors to see what diamonds they offer and compare.

The beginning of your search must be the diamond shape. Each diamond shape has different search criteria such as clarity, symmetry and color that works best. Each shape has a different cost so searching multiple shapes at the same time will leave you frustrated. For example, Take a look at this 1 carat SI 1 clarity H color Princess cut diamond for $3,340 vs this Round 1 carat SI1 clarity H color Diamond for $4,610. Each shape has there pros and cons.
Round is the most popular and is labeled the Cut King. If your significant other isn’t leaving hints of their favorite shape, take a look at their Pinterest or maybe ask a best friend to be sure you pick the diamond shape of their dreams. Round is the most popular following Princess, Oval, and Emerald.
Once you have chosen the shape, its time to understand how the 4 C’s (Carat, Clarity, Color and Cut) interact with it. The 4 C’s represent the most important definitive characteristics of a diamond.
I always recommend to start with your goal in carat weight. So when you go to search a site like James Allen, you can specifically only choose to see 1 carat diamonds. See below a sample of what the search sliders look like.
click on the image above to go the their search page
Start at the goal carat weight. You can then adjust the values to see where the prices is in conjunction with your budget. A quick tip. Shopping for a .90 can yield a deep discount versus a 1 carat. Typically, every .50 of a carat means a jump in price. Some times you find a rare 1.85 at a great deal.
Next is Cut Grade. If you are searching for a round diamond, I suggest you search for ideal cut. A fancu shape(any other diamond other than round) does not come with a cut grade from GIA. Too many variables at play so the cut is left for the viewer to decide. I have two articles that I will list showing how to find the right cut grade in both sites. Follow those guides lines if you need a fancy cut.
James Allen Cut Guide – Bluenile Cut Guide.
Color is the next choice to make. You do not need to pick a D or E color. The human eye can’t typically even see the difference between a D or an H-F color. Depending the shape of stone you choose, a G-I color is the perfect range to shop for. Round diamonds hide color very well and a H-I color works perfectly.
Clarity is your next option to choose. The main criteria is to make sure the diamond is eye clean. If I show you a Flawless diamond next to a SI1 that’s eye clean, is there a benefit to the flawless other than bragging rights? Safe money and choose an eye clean SI1 if possible. Diamonds like emeralds typically require a vs1.
If you are under budget, congrats! Feel free to go for a heavier carat weight. If its over budget, keep adjusting the parameters of clarity and color to see how close your budget is reached.

What I love about the different engagement ring options is it can help with the visual tremendously. Lets say you were shy with reaching a certain carat goal. A ring choice like a Halo, Vintage style, or 3 Stone ring will give it the extra size to appear much larger. So a .80 carat diamond on a beautiful Halo diamond engagement ring setting can be a stunner.
Again personal engagement ring preference of your significant other is important. If you are unable to find any information, you can always go by whats popular.

Considered KING when it comes to brilliance. Original round brilliant-cut was developed by Marcel Tolkowsky in 1919. The modern round brilliant consists of 58 facets. The Round Diamond is King in terms of popularity of Diamond Shapes. Known to be the diamond with the most brilliance,fire and sparkle, its no wonder why its loved. Its classical and timeless. The diamonds CUT grade impacts this diamond shape the most. In addition, its know to be pricer than other cuts due to 50% of the rough being utilized to create it. But, Its also a diamond shape that hides clarity imperfections and lower color best. Of all Diamond Shapes, Round is the most popular.
BUYING TIP– Look for a length to width ratio of 1.00-1.03. Remember rounds hide imperfections and lower colors best. Buying the Diamond Shape round with a grade of very good is still a beautiful diamond. Excellent is of course ideal and sometimes doesn’t have such a high premium. Cut is king so if your gonna stretch a budget, cut is the thing to do it for.
Each site has a premium round. I would say with proper homework you can find a beautiful round diamond outside of these prime selections. Consider these no guesswork, hand picked selection for ideal cuts.
James Allen sells the Ultimate in Diamond Brilliance, look for a Hearts and Arrows True Hearts Diamond. Seen from above, a Hearts and Arrows diamond shows an arrow pattern. When displayed on its pavilion side, the diamond presents the eye with 8 hearts with tiny ‘v’ shapes. Genuine Hearts and Arrows have these patterns visible at a single glance, indicating that the diamond has perfect optical symmetry.
What I love about James Allen is they provides actual photographs of all the True Hearts Diamonds. You know when you go this route, you are getting the top of cut, symmetry and polish for a reasonable premium.
Blue Nile has there Astor line. Here is a link for a filtered Astor Round Diamond. This is Blue Nile’ s hand picked selection with triple excellent diamonds scoring excellent in Cut, Symmetry and Polish. On their website it reads, “Exceptionally rare, only 1 in every 1,000 diamonds possess the potential to achieve Astor by Blue Nile™ status. They are curated and analyzed by two independent industry experts to unlock ultimate brilliance.”. Sounds like a steal if the price is right.
I tell my clients, it doesn’t hurt to compare your findings against a top teir selection. Sometimes the premium is slight which if its in the case inside of budget, a perfect cut is the most valuable aspect of the diamond. This is not the only way to find a beautiful diamond, it just takes the guess work out.
The princess cut is the second most popular cut shape for diamonds. The princess cut is a relatively new diamond cut, having been created in the 1960s. It is cheaper to buy than the round as the rough is utilized more. Compared to other diamonds in the same shape, Princess cut diamond give out more brilliance and sparkle than the others. Beware when purchasing. BUYING TIP. GIA CERTIFICATE DOES NOT grade CUT for the princess. Its very important to use a company like James Allen or Blue Nile that has detailed images of the diamond. A diamond with a good shape and sparkle will stand out. The only certificate that grades CUT in fancy shapes like the princess is AGS . Of all Diamond Shapes, Princess is the second popular.
Here are things to look for:
AGS certification is the only trusted cut grade for Princess. Click HERE, I have created a custom search link in James Allen for Princess Cuts with only AGS certification. Here you can insure you have a great cut certified. You can also ways play with search criteria from these sites under certification. Its not the only way to find a great cut. Images help the buyer see the diamond sparkle. You can always contact us by clicking here for search advice.
Brian Gavin has a selection of their personal collection they have cut themselves for Princess, all coming with AGS certification as Excellent cuts. I would say this selection is Brian Gavin’s biggest strength. Click HERE to find them.
Oval-Cut Diamonds give a beautiful sparkle and style. It’s recommended you choose an H color to be on the safe side and Si1 clarity. Occasionally you can find an SI2 that looks great but it’s not too common. The length to width ratio is equally important to ensure you have a classic oval shape.
One must evaluate an Oval diamond closely as it’s not as simple as a round. GIA doesn’t classify cut grades for any shape other than round. You will have to analyze the stone with other criteria.
Take a look and click on this link to view an oval diamond that has the same 4 C’s but has a drastic difference in cut and look. Stone A vs Stone B You can see the shape of the diamond is the most important feature, not the traditional 4C’s.

Growing in popularity, the cushion cut is know as the romantic stone. Known for its sparkle in a candle lit setting. Once referred to as old mine cut. It combines a square cut with rounded corners, much like a pillow (hence the name). Traditional cushion cut diamond shapes return light in a chunkier pattern than modern cuts. I would say that the cushion looks amazing in a vintage style ring. If vintage is your thing, cushion is a winner. They are not available in abundance, so online is the way to go.
Cushion cut in an ideal shape are bottom heavy. When searching, find a Cushions with a depth under 70% and a table under 70%. Any depth over 70 runs the risk of extreme bottom heaviness. Causing the diamond to go lifeless and appear smaller from the top view. This is not to have you shy away from this purchase but thats just the nature of the shape.
GIA CERTIFICATE DOES NOT grade CUT for CUSHION DIAMONDS Its very important to use a company like James Allen or Blue Nile that has detailed images of the diamond.
Here are things to look for:
Since GIA doesn’t give Cushion Cuts cut grades, I highly recommend to click this link to Brian Gavin’s Cushion cut hearts and arrows line. 
Its all AGS certified as excellent cut. Brian Gavin is a master diamond cutter that has created Excellent cut grades for Cushion, Princess and Emerald.
James Allen also allows you to search for AGS certified only stones. Here is a custom search link only showing AGS certified stones. Again, this isn’t the only way as you can inspect cut with your eye or reach out to me here. This way only takes the guess work out.
The Pear Diamond is so unique, often referred to as the tear drop shape. Probably not the most popular but stands out. Its probably one of my personal favorites. Its different, has a beautiful sparkle and gives a large appearance. The pear is a combination of a round and a marquise shape, with a tapered point on one end. Another big plus is it hides imperfections well like the round. Color has to be H color or better.
Color starts from the tip of the diamond which is front and center to the eye. See example of a J color. 
Length to with Ratio is a Huge factor in this shape. Usually between a 1.50- 1.70 is considered ideal. This is also Subjective. To short and you have a stubby diamond. Too long and it looks like a skinny tooth. See below.
As you can see, its vital to see a picture or detailed 360 image like James Allen or Blue Nile has when buying this shape.
WARNING- Look out for Bow Tie Effect. Its usually going to be slightly evident but you don’t want a strong characteristic of the bowtie. See images below to learn why they call it the bowtie effect.
BUYING TIP: While the length to width ratio of classic pear shaped Diamond Shapes is 1.40-1.70, personal preference will again dictate choice.
things to look for:
The unique look of The Emerald Diamond is created by the step like cuts. Its table is wide open and the diamond has a mirror effect rather than a shimmering diamond characteristic. This diamond may not have a lot of sparkle, but its classy and elegant.
Length to Width is a huge buying feature to look out for. a 1.50 is considered ideal length to width ratio, however the 1.30 l/w is starting to get popular. This goes down to personal preference. Take a look at the samples below for length to width ratios and howe they change the appearance of the diamond.
As you can see, its vital to see a picture or detailed 360 image like James Allen or Blue Nile when buying this shape.
