This is an admirable stone! The best blue tanzanite in our collection, from the only mine in the world in Tanzania. The stone weighs more than 25 carats, with high purity. The deep blue color makes this specimen of gem-quality tanzanite look like a natural sapphire in the shade of royal blue, translated as “royal blue”. This color is the standard of the best tanzanite color.
The classic cushion cut is ideal for a large cauldron ring or signet ring.
