Quartz crystals are usually hexagonal and prismatic, and often twinned.
Clear quartz crystals were once believed to be petrified ice, and are used in meditation for transmission and amplification of energy. Rose quartz, with traces of manganese or titanium, is found primarily in the U.S. and Brazil, and is believed to reduce stress and encourage compassion. Other prized silicates include amethyst, citrine, tiger's eye, aventurine and chrysoprase. SOLD Click for closeup picture Arkansas Large Cluster, a Sculpted Design Masterpiece.
