CUT

DIAMOND CUT

The Diamond cut is the quality the breathes life into the stone. The allure and beauty comes from the diamonds fire, sparkle and brilliance. By far the most important C in the 4 C’s of Diamonds. These are the major components that attribute to the Cut grade.

4 C's of Diamondsvia GIAThe major components, from top to bottom, are the crown, girdle and pavilion. A round brilliant cut diamond has 57 or 58 facets, the 58th being a tiny flat facet at the bottom of the pavilion that’s known as the culet. The large, flat facet on the top is the table. The proportions of a diamond refer to the relationships between table size, crown angle and pavilion depth. It is important to note that a wide range of proportion combinations are possible, and these ultimately affect the stone’s interaction with light and how attractive the diamond is to the person viewing it.”

An important wording to point out ” wide range of proportion combinations are possible”.  Sometimes the most ideal numbers don’t add up once you add up all the angles and attributes. Each stone is different.  This especially holds true to Fancy shapes(anything other than a round diamond).


Huge Tip:

Round diamonds are the easiest to buy regarding CUT.  Gia offers a cut grade only for Round Diamonds.  All Other Shapes like Princess, Emerald Cushion don’t have an official cut grade.  You have to evaluate the stone by eye and various elements such as table and depth percentages.  If this is confusing, please contact me here so I can guide you.     

James Allen, Blue Nile and Brian Gavin all have their signature line of cuts.  If you are buying round you may not need to go there, however for any shape such as Princess, Cushion, etc.  It’s not a bad idea to look.  Pricing is fair for the quality.

Blue Nile has Their Astor Line.  They have brilliant Princess and Cushion cuts.  If you are shopping for those its worth taking a look here.

Brain Gavin has its Signature Diamonds Cut Line which often come with a AGS Diamond Certificate.   Its the only certificate focusing on light performance of a diamond.  Brian Gavin is a master diamond cutter that is known for the best cuts.  I Highly recommend a Fancy Shape Diamond(Princess,Cushion, Emerald, Oval ETC) to have a AGS Certificate.

James Allen doesn’t have a signature series but that doesn’t matter.  In there filters for diamond search, you can put AGS diamond certificate.  This means any fancy shape diamond with a grade of  O (ideal) means its a brilliant light dazzling diamond.

Your Fancy Shape Diamond(any diamond other than round)  wont display a cut grade, you must click on AGS diamond certificate picture and read.

A signature series is nice because it takes the guess work out of it.  But not always necessary to find a beautiful diamond.  In the end you must gauge price with attributes.   I give my clients options for the top 3 diamond providers so they can compare offerings.  Each company has their strengths. 

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 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.

Brian Gavin opened in 2009. He is a 5th generation Master Diamond Cutter. He is an authority when it comes to crafting Hearts & Arrows Diamonds and is well respected in the industry.  The company sells reasonably priced diamonds.   An excellent brilliant Cut grade is the focus of Brain Gavin and its his biggest PRO.  Many stones are AGS Certified with excellent cuts and this is helpful with fancy cut diamonds(Princess, Cushion,Emerald, etc).  A negative  is a 15 day return policy. Most will prefer more time however its still a respectable amount of time.  A client should know quickly  if  pleased with a purchase. There are also some exceptions to certain custom work. Feel free to dig deeper in the about section of his site as it may not apply to your purchase.  Click of the Brian Gavin Logo or this link to see their site.
