Your chance to own a piece of history: tanzanite gemstones are running out fast, and once they're gone, they're gone. Through time the price of tanzanite will continue to rise, especially for good quality stones such as these. Each tanzanite used to create these earrings is carefully examined by experts to ensure an exact match and almost flawless internal structure. Two natural tanzanites, grade AA - bluish violet, total 0.95 ct for both earrings combined. Round cut. Post with friction back to fasten.
