Blue Sapphire Crystal, Sri Lanka, Unheated, 3.98 ct For Sale

Here we have a natural unheated sapphire crystal from the famous alluvial deposits in Ratnapura, Sri Lanka. I acquired these crystals from an old German gem dealer, he used to visit Sri Lanka at least once or twice a year and he accumulated a large amount of sapphires. I was able to go through the collection and pick out my favorites.
