The described gemstone exhibits an impressive weight of 42.288 ct, and is among the largest Kashmir sapphires ever certified at SSEF. Colour and purity, combined with a very pleasant shape and cutting style make this stone an outstanding gem. The velvety blue colour and the inclusions found by microscopic inspection represent the hallmarks of the reputed deposit in Kashmir. The stone has been spared from the exposure to any treatment and its clarity and colour are natural. The velvety blue of this stone is due to very fine inclusions and a combination of well-balanced trace elements in the stone, typical and characteristic for sapphires of Kashmir. Natural sapphires from Kashmir of this size, colour and clarity represent a great rarity and the described gemstone with its combination of outstanding characteristics is a very exceptional treasure. With Gübelin Gem Lab appendix stating: One of the most significant events in the history of the blue sapphire occurred in the early 1880s.

Although Kashmir has produced only a limited number of gems since the 1920s, the soft, velvety blue colour of Kashmir sapphires remains the epitome of this gem variety, and is highly regarded by connoisseurs and collectors alike. Gentle and bright at the same time, both gleaming and flattering, the typical hue of Kashmir sapphires is among the most sought after of colours. The late Dr. Eduard Gübelin described this unique and rare colour as: "soft and velvety, scintillating yet bland at the same time; it is a clear, deep blue, enhanced by a gentle admixture of kingly purple." The natural Kashmir sapphire of 42.28 ct described in the above mentioned Gübelin Gem Lab Report is one of these exceptional gemstones. It possesses a richly saturated and homogeneous colour, combined with a high degree of transparency, and a finely proportioned cut. In addition, this extraordinary gemstone has been spared of thermal treatment. Such a combination of characteristics is very rare in natural Kashmir sapphires of this size. With C.
