How can you tell if a sapphire is from Kashmir?

Kashmir sapphires showcase several unique characteristics that indicate their origin, the most famous of which is their colour. The colour of a Kashmir sapphire is typically a deep cornflower blue with a milky softness, often described as velvety. Kashmir sapphires also possess exceptional clarity and slight variations within their silk, which differentiate them from Ceylon or Burmese stones. These inclusions are much finer, often appearing as minute dots in a snowflake-like pattern. While these visual traits are a useful guide, the exact origin of a sapphire can only be confirmed through gemmological certification. If you are looking for a Kashmir Sapphire ring for sale, we recommend purchasing through a reputable retailer.

How to take care of Kashmir Sapphires?

Kashmir sapphires are members of the corundum family, corundum is one of the hardest gemstones, second only to diamond, making sapphires highly durable and suitable for everyday wear. To clean your Kashmir Sapphire ring, soak it in warm water with a small amount of mild soap. Gently brush the stone with a soft bristled toothbrush to remove any dirt or oils, then rinse thoroughly and dry with a soft, lint free cloth.

How much are Kashmir sapphires?

Kashmir sapphires are among the rarest and most sought-after coloured gemstones in the world, and their value reflects a combination of the 4 Cs , as well as provenance and certification. Stones exhibiting the celebrated "cornflower blue" colour, a velvety, slightly violetish blue with strong saturation and a medium tone, command the highest prices, with value rising sharply with carat weight and clarity. The original Kashmir deposits in the Padar region were worked intensively only between 1881 and 1887 before being effectively exhausted, and the small quantities recovered since have done little to alter the market. This extreme scarcity means that certified Kashmir sapphires of significant size are exceptionally rare, and at auction they routinely achieve two to three times the price of comparable sapphires from Burma or Ceylon.

What is the best colour for a Kashmir Sapphire?

The most highly desired colour for a Kashmir sapphire is a rich, velvety cornflower blue. This unique appearance combines depth with a soft, almost milky look, giving the stone its characteristic “velvety texture”. The finest examples display strong hue and saturation while maintaining their brightness. The colour is vivid, even and not overly dark. It is this unique combination of characteristics that forms the most desirable Kashmir sapphire colour.

The stories behind our Kashmir sapphire Rings

Kashmir sapphires have a long history of being universally recognised as the finest sapphires in existence. In 1896, the German mineralogist Max Bauer described the stone of Kashmir as ‘The most beautiful sapphires known’; similarly, George Frederick Kuntz, head gemmologist for Tiffany & Co. in ‘The Book of the Pearl’ in 1908, noted: "The sapphires from Kashmir possess a beautiful cornflower-blue colour which has not been equalled by stones from any other locality." These sentiments were uttered only years after the mines of Kashmir had been exhausted and still hold true to this day.

Every Kashmir sapphire in our collection is natural and untreated, retaining the colour and character it developed naturally within the earth. This keeps the stones true to their origins while preserving the integrity of the antique settings and traditional craftsmanship in which they were first presented. For us, this combination of natural beauty, history, and craftsmanship gives these rare sapphires their enduring appeal as jewels to treasure and pass down through generations.
