Actually, chrysoprase is a chalcedony that derives its color from nickel - apple-green. But if you look at it from a different point, you can see it in blue, just like in our fanart Gradient cursor pack with Chrysoprase Gradient pointer. As a valuable stone, its hardness and striking color make it a popular gemstone for jewelry and carvings. Sometimes, you may encounter the term “prase” used to describe chrysoprase gems with darker tones.
