Chrysoprase is highly prized for its opalescent minty, apple-green color, which is especially unique and is owed to its distinctive coloring agent. | The name 'chrysoprase' originates from the Greek words, 'chrusos' and 'prason', meaning 'gold' and 'leek', respectively; referring to its leek-green color and the presence of golden inclusions. Chrysoprase frequently occurs in quartz veins of nickel-bearing serpentine rocks and in weathered deposits of nickel ore materials. Chrysoprase, like all other varieties of cryptocrystalline quartz, is composed of crystals that are too fine to be seen as distinct particles, even under magnification. | Chemical Formula: SiO2, Silicon dioxide; Color: Green, apple-green; Hardness: 6.5 to 7 on the Mohs scale; | (The above information is provided solely for informational purpose.
