CorundumStones Mining Estate
CorundumStones Mining Estate operates sapphire mines in Sri Lanka & Madagascar. High-quality items are directly offered through this auction-channel. Commonly but not always, our stones were meant to be for Jewelry firms designing rare high jewelry masterpieces. Our focus lies in single origin, unheated sapphires, masterfully handcrafted cut. Roughly 85% of our material is entirely untreated, directly from the mine to the auction. The remaining 15% heated only stones are clearly marked as such. Every single item in our catalog is unique and certified by a reputable Gem Laboratory.
