Kashmir Sapphire’s – an Internal Perspective

Sapphires come in a range of colours from the “deep blues of the evening sky to the shining blue of a mid summers day” (ICA, 2014) and will never go out of style because of the versatility of the colour blue.

Over the last year I have come across various types of Sapphire’s from cobalt glass filled Sapphire’s to synthetics in their various forms. Representing royalty because of its rich colour and durability Sapphires are second to Diamonds in hardness and have been used in jewellery and other ornaments from centuries ago.

Out of all the ones i’ve briefly seen, Kashmir Sapphires have proven to have excellent colour and clarity giving them their reputation in the gemstone industry.

I began to wonder what made the Sapphires from the Kashmir geological region so special for them to be sold at such high premiums and with each document I read about these truly magnificent gems I began to understand what it was that made these gems so mystical.

As we know Sapphires are generally very included gemstones and when they come eye clean and in large sizes they command premiums because of their rarity. Kashmir Sapphires just like ones from other regions are quite included with fingerprints, colour zoning, growth bands, needles etc.

These Sapphires have soft and subtle inclusions which are only clearly visible under magnification.

Blocky and milky growth bands made of Fe and Ti oxides scatter incoming light resulting in the bluish sheen that are seen in these  Sapphires.

Crossing dust tracks are also a common feature but they are faint and can barely be seen without magnification.

These inclusions contribute to the velvety appearance seen in these Sapphires giving them a high price tag. 

One important fact that should be noted is that Kashmir origin should not be used to mislead customers by selling stones from other geographic regions.
