Our namesake

Four measures of a truly exceptional diamond.

We took our name from the standard the world uses to judge a diamond's worth. It is also the standard we hold ourselves to in everything we sell, set, and repair.

C

Cut

The precision of every facet, releasing the fire and scintillation that gives a diamond its living light.

C

Color

Graded to the subtlest degree, we select stones whose rarity is measured by their flawless absence of hue.

C

Clarity

Each piece is examined under loupe and light so that what you take home is as pure as it is beautiful.

C

Carat

From delicate everyday pieces to heirloom statements, weight chosen to suit the moment and the wearer.
