About Chrysoprase

Chrysoprase is a green variety of chalcedony, a fibrous quartz aggregate. Coloured by tiny inclusions of pimelite, this is a rare example of a green gem whose colour arises from nickel. Chromium, which imparts a green hue in emerald, can also create green chalcedony. However, this chrome chalcedony constitutes a distinct gem variety from chrysoprase.

Gemologists describe colour using hue, tone, and saturation. For chrysoprase, the primary hue is green, and top-colour gems are a bright, apple green. Secondary hues of yellow or blue may be present. However, secondary yellow hues are undesirable. Top-quality specimens won’t show these.

Facts:

  • Mohs hardness: 6.5
  • Mineral: Fibrous Quartz Aggregate
