The INFERNAL is a handcrafted black tungsten carbide men's wedding band, 8mm wide, with a genuine Hawaiian koa wood inlay sealed under clear resin, channel set across a hand-hammered black flat pipe-cut body. Built comfort-fit, inside-laser-engravable, and backed by our lifetime warranty - a wedding band that layers forged black tungsten with warm Pacific-island hardwood grain.

The Metal

Tungsten carbide is the hardest wedding-band metal made - roughly 4× harder than titanium and 10× harder than 18k gold. That's not marketing language; it's a measurable Mohs hardness of 8.5-9. In practical terms: this band will not scratch from keys, tools, gym equipment, or daily contact with desks, steering wheels, or phone cases. It will look the same in five years as it looks the day you open the box.

The black tone is a PVD (physical vapor deposition) finish - bonded to the tungsten core at the molecular level, not a paint or plating. It won't peel, strip, or wear through. The metal is fully hypoallergenic and nickel-free. The flat pipe-cut profile gives the band hard 90-degree outer edges and a level face, and the hammered facets are struck into the tungsten before PVD so the texture is structural. The koa wood is channel set flush across the center and sealed under clear UV-stable resin.

The Hawaiian Koa Wood Inlay on Hammered Black

The INFERNAL pairs two tactile elements: a hand-hammered black tungsten body and a genuine Hawaiian koa wood inlay at the center. Koa is a prized hardwood native to Hawaii, known for deep golden-brown grain that shifts from caramel to nearly copper depending on the cut - highly figured wood used in traditional Hawaiian canoes, guitars, and fine furniture.

Across the hammered black field, the koa grain runs like warm lightning. Because each ring uses a different section of wood, no two rings carry identical grain - yours will be unique. The hammered facets on either side of the inlay catch light at dozens of angles; the wood absorbs light warmly. From a distance the ring reads dark with a warm center band; up close the hammer marks and koa grain are the story.

Who It's For

The INFERNAL is for the man drawn to Hawaiian or Pacific-island craft - koa wood is iconic in Hawaiian material culture, and pairing it with a hammered dark body reads as forged and earthy rather than polished. If you love the ocean, surf, work with wood, or simply want a wedding band with natural material and hand-wrought texture, this is the band.
