Inclusion profile
Uniform surface tone and a smooth dome profile, selected for tactile presence rather than facet performance. The cabochon format tolerates natural porosity without visual compromise.
A warmer, sculptural interpretation of black diamond luxury, inspired by object-led jewelry design. The dome profile shifts the conversation from brilliance to mass, touch, and silhouette.

In-depth analysis
Light behavior
Continuous luster with no aggressive flash. It behaves more like a polished black artifact than a conventional diamond. The dome amplifies ambient light into a single, sustained glow.
Provenance and certification
A strong reference for clients who want black diamond jewelry to feel warmer and more sculptural. Made-to-measure with optional hand engraving on the inner band.
Wearability profile
Comfortable for formal daily wear because the dome has no exposed corners. The polished surface resists minor surface abrasion better than faceted stones.
Care and handling
Polish cloth only. Avoid abrasive compounds on the gold dome. The smooth surface shows fingerprints more than faceted stones — a quick cloth maintains its appearance.
Investment note
The sculptural format appeals to a distinct collector demographic — those who view jewelry as wearable art objects rather than asset vehicles.
Curatorial analysis
The dome profile shifts the conversation from brilliance to mass, touch, and silhouette.
Yellow gold adds warmth and makes the black center feel ceremonial rather than purely severe.
It diversifies the collection so the catalog does not become only sharp, faceted stones.
