Zimbaprase®, Chalcedony, Africa

  • Zimbaprase® also marketed as Aquaprase, is Chrysoprase a silicate mineral, and its unique color is caused by tiny inclusions of Nickel silicates that refract the light. A combination of Chromium, Nickel, and Zinc contributes to the unique powder blue- to bluish-green color spectrum. Because it is a chalcedony, it is hard, durable, and lustrous, ideal for jewelry making.
