Cut:

8/8

You’ve selected a 15.62 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 15.62 carat Round lab diamond is graded SI1 clarity, which stands for Slightly Included 1. Read more about SI1 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:

The customer service and craftsmanship are both excellent. They are super easy to work with! My only wish is that they make their rings just a tad bit thicker or give you the option to select thickness.

This was exactly what I was looking for. Something nice reliable and not super expensive. My fiancée loved it and I couldn’t recommend this to all. We will definitely be buying more things in the future

I was looking for some earrings for my wife, but had no idea what I wanted. The Rare Carat experience walked me through it step by step, and when I had questions, one of their team members was immediately available to chat and offer expert advice. I highly recommend them for quality, price, and customer service!

Everything was on time, progress was well coordinated and the end product was perfect! I have already referred someone to Rare Carat for an engagement ring. With declining customer service everywhere - my experience with Rare Carat was above and beyond! Highly recommended!
