Jewelry materials guide: plated, stainless steel and sterling silver
What gold-plated, stainless steel and 925 silver really mean, how to avoid skin reactions and how to judge stones.
Jewelry on AliExpress ranges from inexpensive fashion pieces to genuine silver, and the material decides how long it lasts and whether it irritates your skin. This guide explains the common terms.
Plated jewelry
Gold-plated or silver-plated pieces have a thin coating over a base metal. The coating wears off with time, sweat and friction. Thicker plating and a stainless steel or silver base last longer. 'Gold-filled' pieces have a thicker layer than plated ones, while solid gold is marked with a karat number such as 14K or 18K.
Stainless steel
Stainless steel, often 316L, is durable, does not tarnish easily and is suitable for most people. It is a good choice for everyday rings, chains and watch cases.
Sterling silver
Real sterling silver is 92.5% silver and is usually marked 925 or S925. It can tarnish, but a soft cloth restores the shine. A very low price for a large silver piece should make you doubtful.
Skin reactions
Nickel is a common cause of skin irritation. If you have sensitive skin, look for stainless steel, titanium, solid gold or sterling silver, and avoid listings that do not say what the base metal is.
Stones
Cubic zirconia and glass are common in affordable jewelry and look good but are not diamonds. Moissanite and lab-grown stones are real gem materials sold at lower prices. Check what the listing actually says, and treat 'diamond' on a very cheap item with caution.
Size and fit
For rings, use the inner diameter or circumference in millimetres and compare with a ring you own. For bracelets and chains, check the length in centimetres.
Care
Take jewelry off for swimming, showers and exercise. Store pieces separately in a dry place, which slows tarnish and scratches.
