2.3" Wide, Natural Chrysoprase Specimen - Poland

 
This is a natural specimen of chrysoprase, which is an apple-green variety of chalcedony. The color is caused by tiny inclusions of nickel bearing layers silicates like willemseite and népouite. A lot of ordinary chalcedony is dyed green in an attempt to simulate chrysoprase. Dyed materials often have a near-perfect appearance and a consistent green color. Genuine chrysoprase usually exhibits some variation in color, saturation, or diaphaneity. It also often contains included materials.
