They are among the most highly-prized gems due to their rarity and their scarcity and the mine that yielded the finest specimens was largely exhausted by 1887, after only a few years of production. Today, Kashmir sapphires set the standard against which all other sapphires are measured and are avidly sought by collectors who are prepared to pay princely sums for top-quality specimens from this extraordinary period in the history of gemmology. 喀什米爾 出產自喀什米爾的藍寶石有其獨特艷麗天鵝絨般的藍色色調。由於產量稀少及罕有，它們是最價格昂貴寶石之一; 現時緬甸和斯里蘭卡仍然出產非常優質的藍寶石，而喀什米爾在這幾十年來巳沒有採礦活動，出產最優質的藍寶石礦床經僅僅六年在1887年已經耗盡。 今天，喀什米爾藍寶石製定了衡量所有其他藍寶石的標準，並被收藏家熱切追捧, 對于來自寶石學史黄金歲月裏的最優質寶石, 他們不惜為之一擲千金。
