Cut:

8/8

You’ve selected a 1.50 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 1.50 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:

Even better in person. I feel like the photos did not due the ring justice. The finish is amazing and the diamond we ended up with is like a disco ball. Quite literally when my fiance drives the sun refracts and see glittering on the car ceiling. The measurements were useful to make sure I got the ring that was right.

Great customer service. Knowledgeable gemologist. Felt confident buying a natural beautiful D FL stone GIA certified with a value of over 30K. Great price, similar stones were 2-5 thousand above Rare Karate. The stone arrived on time, confirmed my stone and certification at my local jewler and had my wife's ring completed for the event.
