Temple St. Clair jewels are made in 18K gold, meaning 75% (or more) pure gold alloyed with a 25% alloy mix of silver and copper. Early on, Temple established her own special “formula” of gold, silver and copper to create what has become our signature warm yellow hue. We require that all of our gold is “750 plumb” meaning that our pieces contain just over 75% pure gold content. Each of our gold jewels is marked “750” to indicate 18K gold. The pieces are also marked with our “temple” hallmark of authenticity: the “temple” refers to Temple’s given name and her classical beginnings.


Our gold and alloys, silver and copper, are obtained only from verified sustainable sources. Our gold sources include recycled gold and Fair-trade Gold. Fair-trade Gold supports small-scale miners to receive a fair deal for their hard work, as well as protecting the environment, family and community livelihoods.
