Chrysoprase Quartz

Most Quartz is more than 99.5% chemically pure, more than most other minerals. Pure Quartz, sometimes called Rock Crystal or Clear Quartz, is completely transparent. Violet Amethyst, pink Rose Quartz, yellow-gold Citrine, brown-gray or black Smokey Quartz, or Ametrine - a mix of Amethyst and Citrine, are among the most beautiful and desirable Quartz gemstone varieties while Lemurian Quartz is valued for its purity, distinctive appearance and rarity.
