A men's black thorn 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. Thin branches twist and cross around the band, with small thorns along them and open gaps in between. It's 6mm wide and 2mm thick, polished, with a standard fit.

The branches and thorns give it more going on than a plain band. The black version also comes in silver.

Every piece already comes in a black velvet gift bag.

It comes in US sizes 7 to 12 (UK N½ to X½), so if you take a US 6 or 13 this one won't fit. 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.
