Cut:

5/5

You’ve selected a 0.31 carat Marquise natural diamond. 0% of our users choose marquise 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:

Your 0.31 carat Marquise natural 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.

Clarity:

Your 0.31 carat Marquise natural diamond is graded SI2 clarity, which stands for Slightly Included 2. Read more about SI2 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: 0.31 Carat

However, it's important to note that carat weight is not the same as size, as other factors such as depth and shape can also impact how large a diamond appears.

This was in the email that I sent to Max at Rare Carat who was incredibly helpful. Thank you so much, Max B. About Rare Carat, I think this says it all! "I received the earrings this morning, oh my gosh, they are absolutely perfect. Not only did they arrive ahead of schedule, but the presentation itself was beautiful–every detail felt thoughtful and carefully considered. It truly made the entire experience feel special from start to finish. I have to take this time to recognize how exceptional your customer service has been throughout the process, from me messing up, to today! From communication to delivery, everything was handled with such care and professionalism. It’s rare to find such a seamless and pleasant experience these days. I want to write a letter or email to your company to reiterate just how great your customer service has been. Please let me know where I should send it, and who to send it to. Thank you again for everything–you've made this purchase truly memorable, and I will absolutely be recommending Rare Carat to others."
