|The popularity of pink sapphire is likely related to the fascination with pink diamonds. Pink diamonds are one of the rarest and most expensive of all gemstones, unobtainable for most except the extremely wealthy. |
Pink sapphire is a more affordable alternative, though still rare and hardly inexpensive. Pink sapphire has grown in popularity as an engagement ring.
|Sapphire in the lighter colors tends to have more brilliance, luster and fire. Sapphire has positive connotations, such as faithfulness and sincerity. Sapphire also has superior hardness - 9 on the Mohs scale.|
|Blue is the classic sapphire color, but fine quality pink sapphire is actually rarer. Pink sapphire in large sizes is hard to find. In general, pink sapphire is more valuable than the other colors of fancy sapphire, such as yellow, green and violet. Like ruby, pink sapphire is colored by the trace element chromium, so the concentration of chromium will determine the depth of color. The clearer and more vivid the color, the more valuable the sapphire. Pink sapphire is usually heated to improve its clarity.|
|The most famous sapphires in the world are from Kashmir, and they are extraordinarily rare.|
New sapphires are rarely discovered in Kashmir, and most of the material that exists was discovered more than 100 years ago. Kashmir sapphires are highly valued because the best specimens have a superb cornflower blue colour and a sleepy quality (due to rutile inclusions) that has been described as "blue velvet."
|By 1887 declining production led the Maharajah of Kashmir to request geological assistance from the government of British India, in the hope of finding more material. The British geologist found the original mine to be exhausted, and turned his survey to placer deposits elsewhere in the valley.|
Exploration failed to uncover new sapphire. Over the years geological surveys were mounted and mining efforts undertaken during the three months of summer free from snow. But the marvels that came out of the original mine were never matched, and today the area is mostly under control of Muslim tribes.
