Tanzanite is a December birthstone and one of the world's rarest gemstones, found only in a small region of Tanzania near Mount Kilimanjaro. Its distinctive violet-blue color makes it a prized choice for fine jewelry. As is standard in the industry, the colored tanzanite gemstones have been enhanced. All diamonds are natural and untreated.
Each pair is accompanied by a Jewelry Grading/Gemological Report from a certified gemological laboratory, certifying the authenticity and quality of the stones. Shipping via UPS air, fully insured, is included in the price, with signature required upon delivery.
