About Our Gems

We use genuine stone materials in our designs such as onyx, quartz, spinel, corundum, sapphire corundum and topaz. Some of these are heat-treated to bring out the vibrant colors that you see. Corundum is what mother nature made natural gems from! 

We only choose materials that have a Mohs scale hardness factor of 7.0 or better for beauty and durability. 

 

Our materials vary from batch to batch, depending on what is available in our quantities at the time of purchase. Rest assured that you will receive a high-quality stone that will sparkle for a lifetime of wear.  

About Our Metals 

All of our silver settings are made from USA-grade sterling silver (.925).  All of our gold settings are 10k gold.
