Our two collections

Two families of cut. One obsession with light.

Every design in our library was developed by Jonathan “Rhino” Weingarten, who has spent his life studying the science of cut.

Distinctive

Distinctive

Modern faceted diamonds optically designed around AGS/GIA light performance for edge-to-edge fireworks.

The DG difference

We look past the grading report.

Most buyers are new to diamonds, so we show you everything. Every stone we sell or source for you is examined in our own lab.

01

Structural inspection

Checked for surface-breaching inclusions that could compromise the diamond's integrity.

02

Color & growth review

Screened for brown or blue hues in HPHT diamonds and for internal graining and stria in CVD diamonds.

03

Light performance

Evaluated with the same technologies used by the AGS and GIA labs.

04
