Certification & Report
Cut:
You’ve selected a 4.31 carat Cushion lab diamond. 0% of our users choose cushion diamonds. Learn more about them here.
Cut is the most important factor. When an experienced gemologist picks up a diamond grading report, their eyes go to very specific values. They are looking to see if these fall within the desired ranges. Seemingly unimportant values like the depth percentage have a large effect on how your diamond will sparkle - and these values differ for each shape.
Follow the checklist prepared by our gemologists to see how your diamond fares. If it misses by a little bit on one or two, that’s fine, but we recommend trying to find a stone that passes on all:
Property | Target | Diamond |
---|---|---|
Symmetry | Very Good or better | Excellent |
Polish | Very Good or better | Excellent |
Girdle Thickness | Thin to Very Thick | M. Thick |
Table | 55% - 65% | 60.0% |
Depth | 61% - 68% | 65.7% |
Color:
Your 4.31 carat Cushion lab diamond is graded F color (Colorless), and you can read more about F color diamonds here.
Color is graded beginning with D (Colorless). Learn more about diamond color here. The market prices colorless diamonds higher as they are rarer, but some people prefer warmer colored stones.
Our gemologists check for following color issues before recommending a diamond:
Property | Target | Diamond |
---|---|---|
Color | K-D | F |
Artificial Treatment | No | No |
Fluorescence Color | None or Blue | None |
Fluorescence Strength | Faint or less | None |
Clarity:
Your 4.31 carat Cushion lab diamond is graded VS1 clarity, which stands for Very Slightly Included 1. Read more about VS1 clarity diamonds here, or learn more about diamond clarity in general here.
There are minimum clarities our gemologists prefer for each shape, but beyond that clarity is a matter of budget and preference. People typically aim for an eye clean stone. Also, our gemologists have certain deal-breakers when it comes to clarity. For example, our gemologists always avoid stones with a cavity, because with one wrong hit your diamond can crack.
Use the checklist below to ensure your diamond passes. Consult us before purchasing to see if any other nuanced issues are present:
Property | Target | Diamond |
---|---|---|
Clarity | SI1 or above | VS1 |
Cavity | No | No |
Chip | No | No |
Knot | No | No |
Laser Hole | No | No |
Etch Channel | No | No |
Patch | No | No |

Media & Reviews
Very happy with my purchase! I was initally reluctant to purchase online but after reading many reviews I just did it. I ordered a 0.63 carat lab diamond on 14karat yellow gold 6 prong solitaire, came with a certificate.Came in discrete packaging which is important.Box also contained ring sizers and a cleaning cloth. My ring is very pretty and elegant, love the sparkle, size fit me perfectly, I was also happy that the yellow gold isn't very yellow which I was worried about because it wouldn't fit well with a diamond but the gold color is perfect, kind of a mix between yellow and silver. Great price, great customer service, they helped me change the shipping address to a nearby fedex because I wasn't going to be home for signing. Can't complain about anything, will definitelly consider buying again from Rare Carat.


My fiancé never felt remotely stressed during the process. He had the absolute best experience from picking the setting, to the diamond, to placing the order and receiving the ring. The ring is more beautiful than I could have ever expected. Hannah Diamond Halo Engagement Ring, yellow gold, 1.6 carat marquise
My emerald-cut diamond ring with trapezoid side diamonds is absolutely stunning. When I opened the little wooden box to see my ring, I thought it was even nicer than I had expected. The center stone is exquisite. The workmanship is perfect. I love the little round accent diamonds positioned in the setting below the center stone and think that they are a nice touch. I was kept up to date during the process of ordering and waiting for my ring to be made. I contacted Rare Carat twice by online chat and twice by calling Customer Service for various questions. All of the representatives I had been in contact with were informative, polite, and friendly. Everyone was very concerned that I as the customer was pleased with their answers and explanations. The ring arrived in perfect packaging on-time according to their estimated delivery date. Thanks to Rare Carat for your great service and beautiful product.
