The sapphire exhibits an attractive velvety blue colour, combined with an outstanding purity and a very fine cutting style. The few inclusions found by microscopic inspection represent the hallmarks of sapphires from the reputed deposit in Kashmir, located in a remote part of the Himalayan Mountains in India. The velvety blue of this sapphire is due to very fine and subtle inclusions and a combination of well-balanced trace elements in the gemstone, typical and characteristics for the finest sapphires of Kashmir. This sapphire has been spared exposure to heat treatment and its clarity and colour are thus all natural. A natural sapphire from Kashmir of this size and quality is rare and exceptional
