The mineral chalcedony(chrysoprasus from the Greek word with the mediation of Latin) is chalcedony with a greenish colour like leek, grapes or apple, depending on the deposit -colour due to its nickel content and the way it was formed geologically. Australia, the USA, Russia, Poland, Madagascar, Germany and Russia have a considerable production.It is cryptocrystalline, meaning that its crystals are so small that they cannot be seen under simple magnification, and this distinguishes it from crystalline rocks such as amethyst and others, which are almost transparent and formed from clear hexagonal crystals. Agate and onyx belong to the same group of cryptocrystalline rocks. What is attractive about chrysoprase is its colour rather than its formations. It has a hardness of 6 to 7.
