Leibish & Co. is Highlighting a Number of Blue and Green Fancy Color Diamonds of Special Interest to Collectors:
This month, the company turns the spotlight on its collection of rare blue and green stones.
March 23, 2010 – Leibish & Co., a leading company for fancy colored diamonds, is now highlighting some of its rare and highly sought after blue and green diamonds. Due to their extreme rarity, these stones are not commonly found in most jewelers' collections.

As demand exceeds supply for the blue and green color diamonds, these stones are considered to be a sound and reliable investment and are highly desired by collectors and diamond enthusiasts. The average price appreciation for such stones can vary between 15% and 20% annually, and since people frequently wish to invest in blue and green diamonds, many jewelers are motivated to enter the business – pushing prices even higher.
In December 2008, the Wittelsbach diamond – a 35.56 carat blue gray diamond that once belonged to a King of Spain, broke world auction records and sold for a staggering £16.3 million at a Christie’s auction. "Blue diamonds are rare and to offer a blue diamond of this size, quality, shape and provenance is truly extraordinary," said a Christie’s spokesperson.

In November 2009, both blue and green diamonds broke record per-carat prices when sold at Sotheby’s auction. The largest vivid green diamond ever offered at auction, a rare 2.52 carat stone, sold for $3.08 million in Geneva; while $2.52 million was paid by Swiss jeweler Chalita for a 3.17 carat fancy intense blue diamond.
One of the world’s leading respected authorities on fancy color diamonds, Stephen C. Hofer referred to the high value of green diamonds in his 1988 report: "In the diamond industry, green diamonds are highly valued and greatly admired, especially pure green colored diamonds that show no trace of secondary color modifiers."

Investing and collecting blue and green diamonds is extremely lucrative, as rare fancy colored stones have never depreciated in price. Additionally, the benefits of owning such a rarity – a thing of beauty created by nature itself – go far beyond its monetary value. In the words of Sotheby’s Auctioneer David Bennett, April 2009: "For people who are looking to buy something that nobody else has, or somebody who wants something that is beyond beautiful, a blue diamond is going to be very difficult to find, so when they appear on the market, you have to have a go."
