Hello, pretty. Chrysoprase is so beautiful. It is sort of a cross between turquoise and Peruvian opal as far as color goes. Not to mention, it pairs beautifully with both of those stones! It is a variety of chalcedony, which is a type of quartz. It is written that chrysoprase brings through the vibration of Divine Truth, and promotes joy and happiness, while healing the heart of energies of depression and anxiety. Daa-yam. I shouldn't sell this. Finished with a handcrafted 22k gold locking clasp.
