Certification & Report

Learn About Your Diamond

You’ve selected a 1.00 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:

Your 1.00 carat round lab diamond is graded E color (Colorless), and you can read more about E 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:

Your 1.00 carat round 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:

A diamond's carat weight is determined by its size, with larger diamonds weighing more. Learn more about carat here.
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.
