Mandarin Spessartite Garnet

Mandarin Spessartite Garnet is a rare form of orange garnet colored by manganese.

The combination of vivid color and garnet's high refractive index make spessartite garnet one of the most brilliant stones in the world of colored gems. Its hardness is around 6.5 - 7.5 on the Mohs scale, making it ideal for jewelry.
The gems occur in a range of colors from yellowish orange to reddish orange and orange-red. The pure orange, known as mandarin or fanta orange, is very rare and has been found in only a few deposits in Africa, notably in Nigeria.

Top spessartites are highly sought after by gem collectors and are considered investment grade. Very little in the way of new material has been found recently.
The prices and value of spessartite garnet varies according to the size and quality of the gemstone. Color and clarity are the most important factors. Vivid orange is the most valuable. The reddish and orange-red are also valuable in fine quality. Gems with a distinct brownish hue, or heavily included stones, are less valuable.

Spessartites are not currently enhanced by any method.

High Bejewelled Peacocks

Gem-set and diamond peacock brooch, Gustave Baugrand, circa 1865
The collective term for the birds is “peafowl.” The males are “peacocks” and the females are “peahens.” The babies are called “peachicks.” When peacocks mate, they give out a loud “copulatory call”. But sometimes they are faking it. One-third of the calls were fake, and the birds that made them scored the most hookups.

Lucara Diamond's ‘Lesedi La Rona’ too big to sell?

Industry insiders say Lucara Diamond Corp will have to cut its tennis ball-sized rough diamond to find a buyer. Bidding for the 1,109 carat stone stalled at $61 million at Sotheby's last year — short of the $70 million reserve. Lucara’s CEO William Lamb thought that ultra-rich collectors, who buy and sell precious art works for record-breaking sums at auction, would do the same with a diamond. That bet failed.

There is a “very, very small universe” of companies with the skill, money and network to polish and sell the Lesedi said Lamb. A Dubai trading company paid a record US$63 million for Lucara’s 813-carat ‘Constellation’, while British diamond dealer Laurence Graff bought a 374-carat stone for US$17.5 million.
