A men's black geometric ring that won't turn your finger green. It's 316L stainless steel with black IP plating, hypoallergenic and waterproof, so you can keep it on in the shower and at the gym. It won't rust and the black won't fade. A thin line is cut around the band and turns in a zigzag at the front. At one side the cut goes right through, leaving a small gap. It's 6mm wide and 1.5mm thick, with a flat edge and a standard fit.
The zigzag is the only detail on an otherwise plain black band. The black version also comes in silver.
For a gift, add a gift box in your basket for £3.95. Every piece already comes in a black velvet gift bag.
It comes in US sizes 7 to 11 (UK N½ to V½). Measure the finger you'll wear it on, and if you're between two sizes, go up one.

Material: 316L stainless steel
The metal
316L is a stainless steel alloy. It's strong, non-magnetic and handles high temperatures, and it resists corrosion and staining. It needs little looking after, so it suits jewellery you wear every day.
Made from
69% iron, 18% chromium, 10% nickel, 2-3% molybdenum and 0.03% carbon. The maker heats the metals to a very high temperature and quenches them, which gives the steel its crystalline structure.
Cleaning
Wash it in hot, soapy water and rinse it well so it doesn't mark. Wipe it with a microfibre cloth to keep it looking new.
