Significance

Kashmir Sapphire

In early 1881 a landslide above the Indian village of Sumjam in the Kudi Valley revealed the extraordinary blue stones known as Kashmir sapphires. The people who lived in this remote region of the Himalaya Mountains described as “the region beyond the snows”began trading the stones for salt of equal weight, but when Maharaja Ranbir Singh of Kashmir and Jammu became aware of the extraordinary treasure all stones became his property. Within just six years the original mine was depleted. Occasionally through the years other mines have briefly opened, but they have never yielded the quality stones of the first discovery. The location and harsh conditions discourage mining as well; positioned 15,000 feet above sea level the land can only be mined during the summer months from July to September. The range is reached by traveling through more than 60 miles of rough terrain including treacherous footbridges. These factors assure the majority of Kashmir sapphires on the market came from the original landslide.

While scarcity adds to the allure of these stones, what makes them truly sought after is the velvety color, a rich lustrous blue often described as cornflower, or peacock’s neck, that surpasses the color of all other sapphires. Davis Atkinson and Rustam Z. Kothavala wrote in Gems & Gemology,“Over the years, the term Kashmir has come to signify the most desirable and expensive of blue sapphires.” While sapphires have been used in jewelry for centuries, often as a symbol of royalty and clergy, the Kashmir sapphire has only been known since the 1880s. In the brief period since their discovery, they have gained legendary status for their beauty and rarity. The very best stones were taken by the maharajas as have not been seen since the fall of the raj. It is rare to find a gem quality Kashmir sapphire and this matched pair of 3.66 and 3.69-carat cushion-cut sapphires is a magnificent and rare find.

Golconda Diamond

For any jewelry connoisseur, the name Golconda evokes the richness and mystery of the legendary gems, superb in quality and transparency, discovered in the world’s earliest and richest diamond mines. First discovered in 400 B.C.E., this area in Eastern India quickly became known for producing spectacular stones, a distinction that remained true for two thousand years. In the thirteenth century, the Venetian explorer Marco Polo wrote, “No country but this [India] produces diamonds. Those which are brought to our part of the world are only the refuse, as it were, of the finer and larger stones. For the flower of the diamonds are all carried to the great Khan and other kings and princes of the region. In truth they possess all the treasures of the world.”

In the seventeenth century, renowned French diamond merchant and author of The Six Voyages, Jean-Baptiste Tavernier, returned from India with enough Golconda diamonds to merit a barony from King Louis XIV. Included in the diamonds acquired by the king was the French Blue, which Tavernier described as, “of the finest water,” referencing the gem’s unrivaled and extraordinary transparency.

Within a century after Tavernier’s visit, the Golconda mines were depleted, but they had yielded some of the most beautiful and illustrious diamonds ever unearthed including The Hope, gifted by Harry Winston to the Smithsonian Institution in Washington, D.C.; the Koh-i-Noor, now part of the British Crown Jewels, mounted in the Queen Mother’s crown, in The Royal Collection at the Tower of London; and The Regent, considered the finest diamond in the French Crown Jewels, at the Musée du Louvre in Paris.

Now dormant, the importance of the Golconda mines in the history of diamonds is unparalleled. Large diamonds from this source and distinction are seldom seen today and even more rare and desirable are stones maintaining their original cut. Each diamond in this pair of earrings is a superb example of a Golconda diamond; together the 9.07 and 8.08-carat pear-shaped diamonds are magnificent.
