Historical Reading List: Kashmir Sapphires
April 1, 2024

Although gem corundums of all colors other than red are described as sapphire, blue sapphire is the best known and most valued in the marketplace. For nearly 150 years, blue sapphires from a relatively inaccessible mountainous region of Kashmir along the conflict border between India and Pakistan have been considered the most rare and beautiful of the corundum gems because of a combination of their saturated color, velvety luster, and slightly hazy appearance. The historic mines are in the Himalaya Mountains at an elevation of about 4600 meters (~ 15,000 feet) near Soomjam (Sumjam) in the Pádar District of the Indian state of Jammu and Kashmir. The mines were discovered in about 1881 in metamorphic host rocks (gneisses and schists), apparently as the result of a rock exposure due to a landslide. The mines were worked for a limited period until about 1887 when operations declined, and during which time they produced what is generally considered to be the finest sapphires ever found. In subsequent decades, the area was rarely visited, and mining took place only on an intermittent basis. Given the remoteness of the location, the limited period of sapphire production, and despite the notoriety of the blue sapphires from this occurrence, there is relatively little published information on the deposit itself, although discussions of the gemological properties of Kashmir sapphires have appeared in the literature on a more regular basis.
How to Use this Reading List
This reading list gives you an opportunity to learn more about the history of blue sapphires from Kashmir. Entries in the list are presented in chronological order to emphasize the development of ideas over time. The list is not comprehensive, but is a compilation of some interesting information that has often been forgotten or overlooked.
Many of the articles in the reading list exist in the public domain and can be found online at digital libraries such as Hathitrust, Internet Archive, or other digital repositories. More recent publications can often be found in libraries. Abstracts of these more recent articles can usually be found on the website of the original journal or magazine, and the article itself is often available for purchase from the publisher.
On Sapphires Recently Discovered in the North-West Himalayas, F.R. Mallet, Records of the Geological Survey of India, Vol. 15, No. 2, pp. 138-141, (1882). This is one of the earliest published short accounts of the Kashmir blue sapphire discovery. Although not initially recognized as sapphire, the material was subsequently identified as gem corundum based on its physical properties. The article includes a letter received from A.W. Heyde (a missionary in the area) that provided additional information on the discovery.

The author and his associates had to walk nearly 160 miles through rugged terrain from the nearest small town, and then a similar return distance, to reach the remote sapphire mine area near Soomjam in the Himalaya mountains.
