Chrysoprase is a green stone that is a form of chalcedony, containing small quantities of nickel. It is known as a cryptocrystalline mineral, because the crystals that compose the stone are so fine that they cannot be seen under normal magnification. Other cryptocrystalline stones include Onyx, Agate, and Carnelian.
The green color of chrysoprase is similar to the green of emeralds, but in emeralds the green comes from the inclusion of chromium, rather than the nickel of chrysoprase.
The stone has a Mohs hardness of 6 to 7. It is sometimes translucent, so that light shines through it.
The Greeks, Romans, and Egyptians used the stone to make seals and ornamental jewelry as far back as 400 BC . It is said that Alexander the Great had a girdle that contained a lucky chrysoprase stone that helped him win battles. One time he was bathing in the Euphrates River when snake bit off the chrysoprase stone and dropped it in the river. After that, Alexander didn't win any more battles.
