Cut:

8/8

You’ve selected a 0.30 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 0.30 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 0.30 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: 0.30 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.

They have a forever customer, I cannot say enough to their customer support team. My significant other was leaving on a trip, and I wanted to give her this ring before she left. I purchased the ring online, but it wouldn't arrive on time, or the timeframe was incredibly tight. Their customer support team was exceptional and was with me every step of the way. Especially a lady name Angela, who was on the phone with me for more than an hour trying to help me get the ring on time. They also gave me a huge discount, when the ring went over my budget. They really cared, and I felt that. Lastly, I want to say you talk to real people. I was never on a hold for a long period of time, and someone always picked up my phone or my messages, and gave me excellent service. No AI, no call centers, they were real employees and professionals in the industry. Again, I cannot say thank you enough; and I don't know if you will see this, but Angela, thank you so much for the assistance, and helping me give the love of my life, the ring she deserves.

I spent 2 months looking at engagement diamonds at several Online retailers. I ultimately decided on RareCarat because they had good inventory for what I was looking for and their Customer Service Agents were friendly and not aggressive in having me make a decision/purchase.

I was skeptical, but this has been the best purchase of my life. Rare Carat was able to give me real pictures of the actual diamond I was buying, which is amazing. The ring came perfect - and to the manufacturer, THANK YOU SO MUCH!
