What is sterling silver? Sterling silver is a precious metal alloy of silver, containing 92.5% silver. The sterling silver standard is the finest quality of silver available. The lustrous white colour of our sterling silver chains matches both silver and white gold pendants perfectly.

A gold vermeil chain starts out as a sterling silver base, after which a thick 2.5 microns of real gold is layered over the top to give it extra durability. The luxurious colour of our gold vermeil chains matches both 9K and 18K yellow gold pendants perfectly.
