Learn About Your Diamond

18/18 quality

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:

Good

Very Good

Excellent

Rare Carat Ideal

Property	Target	Diamond
Cut	Excellent	Ideal
Symmetry	Very Good or better	Excellent
Polish	Very Good or better	Excellent
Girdle Percentage	2.5% - 4%	3.5%
Girdle Thickness	Thin to Thick	M. Thick
Table	54% - 60%	60.0%
Depth	59% - 63%	60.9%
Crown Angle	33° - 35°	33.4°

Your 1.50 carat round lab diamond is graded D color (Colorless), and you can read more about D 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:

(G-J)

(D-F)

Property	Target	Diamond
Color	K-D	D
Artificial Treatment	No	No
Fluorescence Color	None or Blue	None
Fluorescence Strength	Faint or less	None

Your 1.50 carat round lab diamond is graded FL clarity, which stands for Flawless. Read more about FL 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:

SI2-SI1

VS2-VS1

Property	Target	Diamond
Clarity	SI2 or above	FL

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.

Fiance came home and was sad one of the smaller diamonds fell out of her engagement ring. Called up Rare Carat and waited no time at all to speak with a representative. Lawrence R. was very helpful and answered all of my questions and explained the ring could be repaired and inspected free of charge. Thank you guys for understanding and helping with the ring. Will be recommending Rare Carat to all of my friends and family.

Great communication at a great price! Got the ring in the mail and it looks great. My only complaint would be the scribe lettering was small and hard to read but not a big deal for me overall.

I am obsessed. I got the bellora solitaire 2mm yellow gold setting with a 1.71ct lab diamond. It is beyond what I expected. Beautiful craftsmanship, the prongs are gorgeous, the diamond is set securely and perfectly. Customer service is amazing. They were able to answer every question and ring arrived before the estimated date. I am blown away by this company. Thank you rare carat!

⭐⭐⭐⭐⭐ — Rare Carat sets a new standard I’ve bought from luxury brands at every level — and Rare Carat genuinely outperforms many of them in what matters most: quality, pricing, and customer care. Support is fast, responsive, and actually helpful. The unboxing experience caught me off guard — the level of attention to detail and packaging was something I didn’t expect at this price point. Exceptional value, no compromises. I’m a loyal customer now and recommend them without hesitation.
