Learn About Your Diamond

14/15 quality

You’ve selected a 1.66 carat emerald lab diamond. 0% of our users choose emerald 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

Your diamond

Excellent

Rare Carat Ideal

Property	Target	Diamond
Symmetry	Very Good or better	Excellent
Polish	Very Good or better	Excellent
Girdle Thickness	Thin to Very Thick	M. Thick
Table	60% - 68%	63.0%
Depth	60% - 67%	68.2%

Your 1.66 carat emerald lab diamond is graded F color (Colorless), and you can read more about F 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:

(K-Z)

(G-J)

Your diamond

(D-F)

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

Your 1.66 carat emerald lab diamond is graded SI1 clarity, which stands for Slightly Included 1. Read more about SI1 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:

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.

I was SO skeptical about buying off a website I saw advertised on Instagram/Facebook - I have never been happier to be proven so wrong. The communication with the representative(s) was so fast and you could tell the company as a whole was invested in making our day special by having the ring make it on time. The shine is amazing and the prongs are not as around as they appear in the website photo (Norah Solitaire) I am utterly impressed and am telling anyone and everyone about my experience. Finger size: 4.75 Ring size: 5 Carat: 1.49 Color: G Clarity: VS1 Cut: Ideal
