This whole valley from Indian side to Pakistan side also presents various type of sapphires in various shades of blue to pink. The first mine that produced the popular royal blue sapphires ceased its operations in the early 1990s. This is making these Kashmir sapphires exceptionally rare today, as newly mined blue sapphires from the original mine are no longer available on the market.
High Demand of Kashmir Sapphire: Due to its unique color and features, the Kashmir Sapphires are having high demand in the market. Kashmir is now a brand name. The buyers want to pay as much as if the sapphire has Kashmir name with the particular color tone. The velvety texture and deep cornflower blue color is making them highly demanded and desirable. The sapphires are often placed at the top of collectors' lists.

Factors of Geography: The beautiful valley of lush green Kashmir has a political instability. As a disputed region, Kashmir lacks autonomy.

Due to this political insatability, new mining operations are not accessible, particularly in Jammu and Kashmir. These circumstances also give challenges to accessing existing sapphire mining sites. However, the outsiders and the foreigners can visit the Azad Kashmir area to explore purplish-pink sapphires.
Availability of Sapphires in the Market: Most of the time, the blue Kashmir sapphires are no longer available on the market. The sapphires found today typically are coming from old collections, and when they do appear, they are demanded with a very high prices. Currently, the gemstone market primarily offers purplish blue, purplish pink, and reddish pink sapphires which are originated from Azad Kashmir, Pakistan. However, due to the high altitude and lack of mining facilities, the production of sapphires in the Azad Kashmir region is very limited and difficult, and gem-quality sapphires are rare. Occasionally, the mines in Pakistani-administered Kashmir produce velvet blue sapphires, but these are also very rare, with the majority of production being purplish pink sapphires.
