Cut:

5/5

You’ve selected a 2.51 carat Cushion natural 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:

Clarity:

7/7

Your 2.51 carat Cushion natural diamond is graded VS2 clarity, which stands for Very Slightly Included 2. Read more about VS2 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: 2.51 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.
