Report number 1089316, dated January 30th 2018 A brief look into the history of these sapphires can help illustrate their value. It all started with a natural occurrence in 1880 in the Kashmir region on the Indian subcontinent.A landslide atop the Himalayas revealed unusual type of rocks under the top layers of soil.These rocks were almost completely bare except for the occasional protruding blue stones. It took many years for the local people of the region to realize that the stones were in fact sapphires. Once news of the discovery reached the Maharajah, he immediately sent a regiment of guards to protect the mine, along with miners to dig out more of the sapphires.The years between 1882-1887, marked an extremely productive period for the mine. It revealed some very impressive gems which were as large as 5×3”. Summers in the region were extremely hot and the miners had to work in these conditions with little to no rest. By the end of 1887, the resources of the mine had been exhausted. Hungry for more, the Maharajah sought the assistance of the British, who by then had ruled in India for more than a decade.With the assistance of British geologists, they found a new mine in the valley below. However, this was also quickly depleted, and to this day, no other deposits have been found in the region. Kashmir sapphires command a high price because they contain a top-quality specimen.You may come across other blue sapphires, Burmese or Ceylonese, but only those from Kashmir have a distinctive tint. Experts call it blue velvet - a dreamy cornflower blue that reflects light under all angles. 127 A PAIR OF DIAMOND PENDENT EARRINGS Each rose-cut diamond surmount suspending a line of European-cut diamonds terminating with a similarly-cut diamond hoop, within collet and millegrain setting throughout, mounted in gold, diamonds approximately 2.00cts total, length 3cm € 1,200 - 1,800
