BOSTIN | Polished Black Tungsten Twin Silver Stripes Domed Wedding Ring — 8mm
The BOSTIN is a handcrafted tungsten carbide men's wedding band, 8mm wide, with a polished black tungsten domed body carrying two thin parallel bright silver stripes running the full circumference across the crown. Built comfort-fit, inside-laser-engravable, and backed by our lifetime warranty - twin precision lines on deep black.
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 on the BOSTIN is a PVD (physical vapor deposition) finish bonded to the tungsten core at the molecular level - not paint or plating. It won't peel, strip, or wear through. The metal is fully hypoallergenic and nickel-free. The twin silver stripes are inlaid bright silver tungsten lines, set evenly apart and flush across the crown.
Twin Silver Stripes
The BOSTIN takes a two-stripe geometric approach: two parallel bright silver stripes on a polished black tungsten dome, set evenly apart across the crown. The pattern is symmetrical and rhythmic - neither too busy nor too plain - and the bright silver against deep mirror-polished black creates clean visual contrast.
From a distance the ring reads as a dark band with two bright accent lines. Up close, the stripes show as crisp inlaid silver tungsten cuts in the surface - precise and architectural. It's a quiet ring built on precise geometry rather than texture or stones.
Who It's For
The BOSTIN is for the man who likes geometric clarity over texture or stones. If you appreciate architectural design - symmetric, rhythmic, restrained - and want a ring that reads precise rather than ornate, this is the band.
