What is sterling silver?

November 28, 2014

Sterling is an alloy that is at least 92.5% pure silver. Silver is the whitest of all metals. Pure silver is very soft. Sterling makes more durable jewelry and has better working properties. It is the standard in North America, Britain and Ireland. It is frequently marked "925". The 7.5% that is not silver is traditionally copper. Our casting alloy, that almost all of our Celtic jewelry is made from is a de-oxidizing alloy of copper, boron and a silicon deoxidizer. This alloy is tarnish resistant and less likely to cause skin problems.
