This is a diamond in its most primal form. Weighing a substantial 3.44 carats, this Opaque Grey Diamond offers a raw, industrial aesthetic that is impossible to replicate.

Unlike standard black diamonds which are often heated to achieve their color, this gemstone is 100% Unheated and Untreated. Its color is pure nature — a complex "Concrete Grey" or "Graphite" hue with a unique surface texture and metallic adamantine luster.

With a diameter of 9.35 mm, it commands attention. It is the ideal choice for a men's signet ring, a brutalist-style engagement ring, or any jewelry piece designed to look rugged, earthy, and powerful.
