SCROLL DOWN TO FIND YOUR DESIRED DIAMOND SHAPE

DIFFERENT DIAMOND SHAPES

ROUND DIAMOND:

    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.

Premium Selections?

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.

PRINCESS CUT:

Diamond Shapes

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:

  1. For Table Percentage, stay under 75%.  Avoid princess cuts whose table percentage is higher than 85% or lower than 55%.
  2. A Depth between 65% and 75% for the best balance of brilliance to size.
  3. Length to width ratio of 1.0-1.05.
  4. Longer Rectangular Princess will be cheaper, and may look better to you(subjective)
  5. Hide lower clarity and color well.

Premium Selection

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.

CUSHION CUT:

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.

BUYING TIP .

  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:

  1. Cushion Cut Diamonds are usually square but can be rectangular as well.
  2. This Diamond was made for a vintage style setting and compliments the look.
  3.  Keep your length to width ratio of 1 – 1.06.  If the stone is the long side, 1.15-1.30.
  4.  You always want to see an image of what you are buying because proportions play a big role here.
  5. Know that it will not look larger than a round.  An Ideal Cushion is likely a bit middle & bottom heavy. This will cause it to appear smaller from top view.
  6. Cushion Cuts have a larger table-So don’t go lower than SI1.  Imperfections are more visible. Color also shows strongly. H color or better.
  7. Don’t expect a super shiny brilliant diamond.  Cushion Cuts are not know for this.

Premium Selection

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. Hearts and arrow Cushion cut 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.

PEAR SHAPE DIAMOND:

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.

Diamond Shape Pear

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.

Pear Diamond Shape

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:

  1. H color or better, as stated earlier color shows strong from the tip.  Feel free to go to SI1-SI2 for the best value.  Try to not get any imperfections on the table of the diamond.
  2. Depth Percentage should be under 66%
  3. Table also under 66%
  4. GIA CERTIFICATE DOES NOT grade CUT for Pear Shapes.  Use a company like James Allen  or Blue Nile that has detailed images of the diamond.

EMERALD

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.

BUYING TIPS

  1. Because of how clear the diamond is, you can see imperfections much easier.  Take a look at this sample round diamond with  a SI2 rating and then the Emerald with a VS2 rating.  Lesson hear you want to stick to vs2 and above.  Remember placement of imperfection is everything.

Recommended Places To Buy

For me to recommend any business, they must meet certain criteria. They must prove valuable to my clients in regards to How to buy a diamond savings and selection | EXPECT 20%-40% LOWER PRICES THAN TRADITIONAL JEWELERS |, time doing business(legitimacy), reputation, and return policy.

James Allen Logo

James Allen  is my favorite vendor.  They revolutionized the ability to get the clearest image of a Diamond with a 360 degree HD image/video and a zoom in up to 40x on all their Diamonds. This without question leaves no doubt on what you are buying.  I argue the ability to see your diamond more clearly than in a physical retail store is a massive plus for you.  They have incredible prices that I will easily  beat retail store pricing.  They have an a amazing 30 day Free no hassle return policy and have been in business for over ten years with countless positive reviews from real customers. The only Con is they are slightly limited in the search filtering ability. Blue Nile  has a deeper way of filtering certain attributes.  Click on this link or Picture to search their inventory.

 

Blue nile logo

Blue Nile was the original online giant that opened in 1999! They probably have the largest selection. In the past they didn’t have images of their inventory but because of James Allen , they were forced to adapt and they now have a large amount of their inventory with images.  There viewing technology is not as good as James Allen  but its still clear and one can evaluate a Diamond with confidence.  Blue Nile  has an incredible 30 day free return policy as well that is insured.  The only Con is they do not have AGS certified goods on their site.  This isn’t an issue for round diamonds but very helpful with fancy shapes like Princess, Cushion, Oval etc… Click on this link or the Blue Nile Logo to see their inventory.
