ALL ABOUT
The colour of Chrysoprase can be lighter to more intense apple-green, though deeper colors are more desirable. Once the color reaches a dark threshold, the gemstone is no longer identified as Chrysoprase, but rather as a variety of Chalcedony known as Prase. Lighter-colored Chrysoprase is a much more popular gemstone material over dark green Prase.

The transparency of Chrysoprase ranges from translucent to nearly opaque. A universal colour consistency increases the desirability and value of this gemstone. The color of Chrysoprase may occasionally fade in prolonged light exposure, so care should be taken to keep these gemstones away from repeated exposure to strong lighting or sunlight. Chrysoprase is very similar to Chrome Chalcedony, which is a green variety of Chalcedony coloured green by chromium impurities. Chrysoprase is usually a lighter shade of green compared to Chrome Chalcedony.
