Radiant cut
Cut corners, brilliant facets, considerably less money.
The radiant takes the outline of an emerald cut and fills it with a brilliant facet pattern, so it holds light like a round while keeping a rectangular silhouette. It uses rough efficiently, which is why it is one of the best values on this page.

- Report

We move enough volume that we will not pretend to know which stone in the parcel becomes yours. What we will do is put a floor under every part of it and let the variance run in your favor — the weight, the clarity and the color can come in above what you paid for, and regularly do.
For example
You order 1.00 ct · VS1 · F.
You might receive 1.10 ct · VVS1 · D.
Same price either way.
What VS1 and D–F actually mean
- VS1
- Very slightly included. Minor inclusions, hard to locate even under a loupe.
- Color D
- Absolutely colorless. The top of the scale, and mostly bought for that fact.
- Color E
- Colorless. Distinguishable from D only by a grader with comparison stones.
- Color F
- Colorless. The last grade before faint warmth appears under laboratory light.

Buying a radiant
The radiant takes the outline of an emerald cut and fills it with a brilliant facet pattern, so it holds light like a round while keeping a rectangular silhouette. It uses rough efficiently, which is why it is one of the best values on this page.
Proportion to expect: 1.20–1.35 for a rectangle, near 1.00 for a square radiant. We cut to the middle of that range, so a radiant from us looks like the shape you pictured rather than a stretched version of it.
Every radiant is laboratory grown, graded by IGI or GIA, and shipped with its report. If the stone that arrives is not the one you want, request a return authorization within 30 days.
