Cut:

8/8

You’ve selected a 3.51 carat round lab diamond. 0% of our users choose round 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:

Clarity:

7/7

Your 3.51 carat round lab diamond is graded VVS2 clarity, which stands for Very Very Slightly Included 2. Read more about VVS2 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:

Diamond Size: 3.51 Carat

Very informative & easy to use website & diamond search. I felt like I got a very good deal, and my local jeweler said it was an "Excellent" diamond. Customer service and contact by the founder was very good.

The ring and diamond i received were perfect. Beyond that the customer service team goes above and beyond. There was some concern that the ring was not going to ship the time frame that I thought it was going to and the customer care team followed up with me several times to keep me in the loop even though the website status was not updating in real time. I have already recommended Rare Carat to several others and will continue to do so.

I was SO skeptical about buying off a website I saw advertised on Instagram/Facebook - I have never been happier to be proven so wrong.<br>The communication with the representative(s) was so fast and you could tell the company as a whole was invested in making our day special by having the ring make it on time.<br>The shine is amazing and the prongs are not as around as they appear in the website photo (Norah Solitaire)<br><br>I am utterly impressed and am telling anyone and everyone about my experience.<br><br>Finger size: 4.75<br>Ring size: 5<br>Carat: 1.49<br>Color: G<br>Clarity: VS1<br>Cut: Ideal
