NEMESIS | Black Tungsten CZ Eternity Wedding Ring — 8mm
The NEMESIS is a handcrafted black tungsten carbide men's wedding band, 8mm wide, with a channel of brilliant-cut CZ stones set edge-to-edge around the band and polished beveled edges. Built comfort-fit, inside-laser-engravable, and backed by our lifetime warranty - a ring built to outlast the job site, the gym, and everything else you put it through.
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: the NEMESIS 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 isn't paint or coating. It's a physical-vapor-deposited (PVD) black finish bonded to the tungsten at the molecular level - the same process used on high-end watch bezels. It won't peel, strip, or wear through. The metal is also fully hypoallergenic and nickel-free, which matters if your skin reacts to other rings.
The CZ Eternity Band
The brilliant stones around the NEMESIS are channel-set cubic zirconia - a diamond simulant, not a natural diamond. We call that out clearly because a lot of bands in this category are marketed as "diamond" when they're really CZ; we want you to know exactly what you're buying. The optical quality is excellent: Mohs hardness 8.5, brilliant round cut, full fire and scintillation under light. Each stone is channel-set flush with the band surface so nothing catches on clothing or gloves.
The contrast of bright CZ against the black PVD is what sells this ring - white stones read sharper on black than they do on silver or gold, and the beveled edges frame the stone channel cleanly.
Who It's For
The NEMESIS is for the man who wants the look of a diamond eternity band in a dark, stealth palette - stones that catch light against a ring that doesn't. It pairs with a black watch, dark suits, or a modern minimalist wardrobe. If you want something bright or gold, see the LEGEND. If you want plain black, see our solid black tungsten bands. The NEMESIS is for the buyer who wants both at once.
