Chrysoprase is traditionally worked with as a heart stone for self-forgiveness, hope and quiet renewal. It is the gentlest of the green heart stones, and it suits people who are generous with everyone else and merciless with themselves.

Meaning & symbolism

An apple-green variety of chalcedony, a cryptocrystalline form of quartz coloured by trace nickel present as fine silicate inclusions such as kerolite and pimelite. It forms through the deep weathering of nickel-bearing serpentinite and other ultramafic rocks, and is found chiefly in Queensland and Western Australia, central Tanzania, Indonesia, Brazil and historically at Szklary in Poland.

Healing properties

Traditional energy

  • Self-forgiveness
  • Hope and renewal
  • Opening a defended heart
  • Quiet joy

Mineralogy

  • Chalcedony (cryptocrystalline quartz)
  • Mohs 6 to 7
  • Conchoidal fracture
  • Coloured by nickel silicates

Look-alikes

  • Green aventurine (sparkles)
  • Jade (tougher, fibrous)
  • Chrome chalcedony (chromium, deeper green)
  • Dyed green agate
  • Lemon chrysoprase (actually magnesite)

How to use it

Carry a tumbled piece in a pocket for daily self-forgiveness work, or hold it over the heart during a short compassion meditation. It sits well beside prehnite for soft heart work and moss agate for slow recovery.

Cleansing & care

Chrysoprase fades in prolonged sunlight and heat, because heat drives off the small amount of water held in the chalcedony microstructure. Never display it on a windowsill and never charge it in direct sun. A brief rinse in water is safe, but skip salt and ultrasonic cleaners. Cleanse with smoke, sound or moonlight instead.

Questions & answers

Yes. Prolonged sunlight and heat dull the apple green, sometimes within a season on a sunny windowsill. Storing a faded piece with a little moisture often restores some depth of colour over weeks, though this is not guaranteed.
