A men's abalone shell signet ring that won't turn your skin green. The ring is hypoallergenic 316L stainless steel, waterproof and sweatproof, and it won't rust or fade. On the face, a thin strip of synthetic abalone shell sits under a layer of resin. The signet is 18mm wide and 3mm thick, with a curved edge and a comfort fit band.
Each strip of shell is different, so no two rings look the same. Wear it on your little finger, where signets traditionally go, or on your index finger.
For a gift, add a gift box in your basket for £3.95. Every piece already comes in a black velvet gift bag.
Sizes run US 7 to 13 (UK N½ to Z½). 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.
