Cut:

8/8

You’ve selected a 5.50 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 5.50 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 5.50 carat round lab diamond is graded IF clarity, which stands for Internally Flawless. Read more about IF 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: 5.50 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.

Well worth the money. The ring is stunning. It’s a little scary buying an item for big $$$$$ sight unseen and over the internet- but Rare Carat is legit!!

So easy to work with, super cooperative post sale.<br><br>I bought a beautiful lab grown twist engagement ring for an unbeatable price, and upon arrival I found I had ordered a size too large, I was able to easily fill out a resize request and customer service helped me with any questions I had. 5 stars!!

Great info on selecting the proper size and metal to hold the diamond. Proper size recommendation, stops the ring from floating on the finger.

Very beautifully set stone, easy to work the website, although I wish the setting could be previewed with another cut other than round, as I got an oval stone.

I bought a ring for my wife to celebrate our 10th wedding anniversary, and the experience was excellent. The website was easy to navigate, the selection of rings was beautiful, and the pricing was good (though it could have been slightly lower). The delivery arrived on time, and the entire process was smooth and hassle-free. Overall, I had a great experience and would definitely recommend it.
