Starting in January 2008, the Central Bank of Armenia, in conjunction with the State Mint of Poland, will be issuing 12 one-oz. Silver Coins.
Each coin will feature both color and a zircon crystal gemstone, and comes with Certificate of Authenticity signed by the Chairman of the Central Bank of Armenia.

THE ZIRCON
Zircon is a mineral belonging to the group of nesosilicates. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, and green. Colorless specimens that show gem quality are a popular substitute for diamond; these specimens are also known as "Matura diamond".
The name either derives from the Arabic word zarqun, meaning vermilion, or from the Persian zargun, meaning golden-colored. These words are corrupted into "jargoon", a term applied to light-colored zircons. Yellow zircon is called hyacinth, from the flower hyacinthus, whose name is of Ancient Greek origin; in the Middle Ages all yellow stones of East Indian origin were called hyacinth, but today this term is restricted to the yellow zircons.

THE SIGN OF AQUARIUS
The Sign of Aquarius is symbolized by the Water Bearer. In much the same way that the Water Bearer brings that precious liquid as a gift, Aquarians shower the world with their thoughts and new ideas. Luckily for Aquarians (and the rest of us), they are at a near-genius level, so their minds churn out some amazing things. Their thought process is also inventive and original. While Aquarians are happy to bestow these ideas as a gift with no strings attached, they are much happier when the rest of the world agrees with them. Naysayers will quickly find out that Aquarians can be impatient, even temperamental, with those who disagree.
Famous Aquarians people: Thomas Edison, Wolfang Amadeus Mozart, Jules Verne.
