Cut:

8/8

You’ve selected a 0.50 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:

Your 0.50 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:

Clarity:

7/7

Your 0.50 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:

Diamond Size: 0.50 Carat

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.

Thought I would leave an update on my recent purchase. After having an issue I was contacted by staff at Rarecarat and was completely surprised by their efforts to rectify the issue. Their level of communication was outstanding! Many thanks to their employees as my wife will be happy with her 2.92 carat wedding set. Get ready for my next purchase very soon Rarecarat!!!

She wanted a statement piece and she loved it. It arrived by expected date and was well disguised with no labeling to give it away. The ring was exactly as it looked online. Of course she said yes!

I'm in Canada and would strongly recommend this process. Way less stress than shopping around from store to store. Great. high-tech tools for viewing and grading their diamonds. The shipping process was great also. It was sent in a 14" box (not in a ring size box or bag). The item must be signed for. I was not home when it arrived, so it went to the closest FedEx until i could grab it.
