Metal Purity

Diamond rings are most commonly set in gold, sterling silver, or platinum. 

 

Sterling silver diamond rings contain 92.5% silver, the remainder of the metal content is an alloy, typically either silver or copper.

Platinum diamond rings contain at least 95% pure platinum, the rest being alloy to strengthen the metal.

Below are metal purity levels for the most common gold karats.  Please note alloys are typically silver, copper, and zinc, although palladium may also be used:
