These beautiful earrings are made with sapphires from the famed Rock Creek deposit near Philipsburg, Montana.  The sapphires have been heated here in the US to improve their clarity and color, but no other treatments have been used.  The sapphires are mined from alluvial deposits along Rock Creek and then heated in Montana.  They are diamond cut for maximum brilliance and all of the sapphires are selected for clarity and are eye-clean or better.

Choose the color and size of the sapphires you want, then put them into your shopping cart. Not all sapphire color and size combinations are available.  The photos shown are examples of each color.  Individual color may vary slightly from the photo but the photo is chosen to be representative of that color.
