Inferra Crushed Stone Inlay Black Tungsten Carbide Ring

The Inferra is a ring that looks as though it was pulled from the earth itself. A hammered black tungsten carbide band with a broad inlay of crushed red jasper, burnt orange and deep earth-toned stone fragments interspersed with raw metallic flakes, it carries a warmth and intensity that is entirely its own. The faceted hammered exterior gives the black surface a raw, geological quality, while the fiery tones of the inlay glow against the darkness with the kind of depth that only natural stone can produce. For those drawn to the elemental and the extraordinary, the Inferra makes an immediate and lasting impression.

Avoid prolonged exposure to harsh chemicals such as bleach or chlorine
Remove your ring before swimming in heavily chlorinated pools or hot tubs

Why Tungsten Carbide

Tungsten carbide has earned its place as one of the most trusted materials in modern ring-making — and for good reason. It ranks among the hardest materials on earth, estimated to be around ten times harder than 18K gold, which means your ring resists scratches and maintains its polished surface through years of daily wear without any special care.

Unlike precious metals that soften and dull over time, tungsten carbide holds its shape and shine permanently. It is naturally water-resistant, tarnish-resistant, and requires no re-plating or polishing — making it one of the most practical and durable choices for a ring you intend to wear every single day. For anyone seeking a ring that combines lasting beauty with real-world durability, tungsten carbide simply delivers.
