The 4Cs
Every scale has a top. We only shop there.
The full grading ranges, and the narrow band we actually buy from. Carat is yours to choose above — the rest is non-negotiable.
We only set D, E, and F — the colorless top of the scale. Everything from G down doesn't get through the door.
VVS means a trained grader needs 10× magnification and patience to find anything. Yours to know about, impossible to see.
Cut is what makes a diamond perform. Excellent, exclusively — we don't negotiate with physics.
* Fancy grey pieces are graded on the colored-diamond scale — the same clarity and cut bar applies.
The Making
From click to knock.
Your piece doesn't exist yet — here's the two to three weeks where it starts to.
Your stone is matched to the standard — D–F, Excellent, VVS — and the casting is scheduled.
New York metalsmiths cast the band in recycled gold; our setters seat the stone by hand.
Final polish, quality pass, and your GIA or IGI certificate and appraisal packed in.
Insured to the door, in a box worth keeping. Champagne optional.
The Comparison
Same stone. Different story.
Side by side, the way jewelers would rather you didn't.
| This diamond | The mined kind | |
|---|---|---|
| Origin | Grown above ground in about six weeks | Dug from a mine — a billion years, then heavy machinery |
| Chemistry | Crystallized carbon — identical | Crystallized carbon — identical |
| Grading | GIA & IGI, same labs, same scales | GIA & IGI, same labs, same scales |
| Price at this grade | The number on this page | Well into five figures |
| Footprint | No mining, recycled gold | It's complicated |
One column costs you money. It isn't ours.
