Zircon has been known since the Middle Ages. The oldest known zircon stones are from Western Australia, with an age of 4.4 billion years. The name probably comes from the Persian word "zargun" which means "gold-colored", though zircon comes in a wide range of different colors. The most popular zircon color is blue. Most blue zircon come in a pastel blue, but some exceptional gems have a bright blue color. Zircon is also available colorless, green, dark red, violet, yellow, brown and orange.
Although relatively hard, (rating 6.5-7.5 on the Mohs scale), zircon is brittle and therefore sensitive to knocks and pressure. The gem has the tendency to wear along facet edges. Its use in rings should therefore be limited to protective settings or occasional wear jewelry. Zircon jewelry should be stored carefully, wrapped in individual twists of paper so that it will not knock against each other.

Many beautiful gems on the site. Love that you are actually shipped the gem that is shown in the photos. Also cool that they give a write up of each gem detailing hardness, characteristics, and best uses for mounting. Great site! Looking forward to seeing these gems in person.
