MATERIALS
We offer a unique range of alloys to choose from across our line. Some alloys must be custom ordered - please inquire on our custom orders page for pricing and turnaround times.
18k Yellow Gold
18k gold is an alloy, which means it is a mixture of gold and other metals. The number 18 refers to the karat value, which is a traditional way of expressing the purity of gold. 24k gold is 100% pure gold, while 18k gold is 75% pure. Yellow gold is 75% pure gold, 15% pure silver and 10% pure copper. The silver and copper balance eachother to leave the color of the 18k gold quite equivalent to pure gold while adding substantial strength and durability. 18k gold is the standard for fine jewelry.
18k Rose Gold
18k gold is an alloy, which means it is a mixture of gold and other metals. The number 18 refers to the karat value, which is a traditional way of expressing the purity of gold. 24k gold is 100% pure gold, while 18k gold is 75% pure. Rose gold is 75% pure gold, 2.75% pure silver and 22.25% pure copper. The copper provides the soft and warm pink color of the 18k rose gold while adding substantial strength and durability. 18k gold is the standard for fine jewelry.
950 Platinum
950 platinum refers to a platinum alloy that is 95% pure platinum, meaning it contains 95% elemental platinum and 5% other metals – typically ruthenium and iridium- added to enhance its workability; it's considered the standard for platinum jewelry due to its high purity, durability, and beautiful white color.
Pure Silver
Silver is the most reflective metal in the world, but in pure form, it is quite soft. Sterling silver is 92.5% pure silver and 7.5% copper. The copper does not materially impact the color and reflectivity of the alloy compared to pure silver, but offers substantial benefits in terms of workability and durability. Sterling silver is food safe, anti-bacterial and some believe that silver can help with stress relief and mood-boosting.
Bronze
We use a premium silicon bronze for our sculptures. Silicon bronze is an alloy of copper, tin and silicon. It offers superior durability and corrosion resistance and polishes to a beautiful light gold tone which is more subtle, nuanced and elegant than brass. Our artifacts are surprisingly heavy in bronze; some weigh over half a pound.
