    A short five years was the lifespan of the world’s most legendary and superior sapphire mine – Kashmir, a remote region high in the Great Himalayan mountains of northwestern India.
    Known for a rich and velvety blue colour that is unrivalled by sapphires form other parts of the world, Kashmir sapphires are beyond scarce. After an alleged landslide in the early 1880’s that revealed a deposit of intense blue gems, mining began under the Maharaja’s control from 1882, for a few years crystals as large as 5 x 3 inches were found on the site. Yet, the fairy tale of these superlative sapphires came to an end in 1887 when production vastly decreased and the deposits were almost depleted.
    Despite continuous efforts to survey new locations for deposits in the region, the results were hugely disappointing. It was a proven common belief that the mine is exhausted.
    With an inexistent supply, high quality Kashmir sapphire like this very one offered here which weighs over 5 carats, unheated and impart with an attractive saturated colour, have become a rarity that are highly covetable among gem connoisseurs.

    五年 - 世界上最有名的藍寶石礦源喀什米爾只有如此短暫的壽命。位於印度西北部喜瑪拉雅山脈高海拔地區,此礦區現在已經成為寶石界的傳奇。
    產首此地的藍寶石因顏色濃郁艷麗、擁有絲絨般的柔亮光澤而享負盛名,無其他產地能及,卻又稀少得難以想像。據說1881一次山泥傾瀉發現了深藍色的礦石,1882印度喀什米爾大君已取得管理權,大規模開採。那短短幾年間,某些開採到的原石尺寸可達5 x 3吋。可惜1887的產量已迅速下降,礦物幾乎已被開採殆盡。
    儘管自那時開始,來自不同地區的專業人員都曾試圖在附近找出新的礦源,但屢試不果,開採到的原石品質令人大失所望。大部分人都相信礦物已經不復存在。
    現今一顆超5克拉、沒經過任何加熱處理的高品質的喀什米爾藍寶石稀珍之程度可謂無容置疑,鑲嵌在此戒指上的就是很好的例子。存世的喀什米爾藍寶數量極度有限,多年來均受到寶石愛好者和藏家的熱烈追捧。
