➡️ Technical specifications

Basalt Prism is a sapphire that impresses with its structure and depth. Its color ranges from a dark, slightly petrol-like green-blue, underpinned by a basaltic origin that gives the material its characteristic density. Unlike vibrant, open blues, this stone remains controlled and enclosed.

Weighing 1.99 carats, the sapphire has a clear physical presence. The trilliant cut significantly enhances this effect: three axes, large facets, and a concentrated play of light that doesn't scatter but focuses. This creates an almost architectural appearance – calm, precise, and deliberately understated.

Natural inclusions are present and visible, but they don't chaotically refract the light; instead, they contribute to the internal structure. Basalt Prism is not a stone for maximum brilliance or brightness. It is aimed at buyers who appreciate material, geology, and form as a unified whole.
