Heated Montana Sapphire Earrings, 3.5-5.0 mm


Beautiful Montana sapphire earrings in simple four prong stud settings, 14k white or yellow gold.



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.  The pairs vary in total weight by size: The 3.5 mm earrings weigh an average of 0.42 carats total, the 4.0 mm weigh an average of 0.62 carats total, the 4.5 mm weigh an average of 0.88 carats total and the 5.0 mm weigh an average of 1.22 carats total.

Choose the color of the sapphires you want and whether you want them mounted in white or yellow 14k gold. Not all sapphire color and gold color 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.
