Green Opal
The Gentle Healer of Heavy Hearts
Also known as: Prase Opal, Chrysopal
About the stone

Green opal is a green variety of common opal—hydrated silica that generally lacks the rainbow play-of-color seen in precious opal. Sources include Madagascar and Tanzania; the nickel-bearing green variety is also called prase opal or chrysopal, names that do not apply to every green opal. Green opal has been used as a gem for thousands of years, while deposits near Haneti, Tanzania, were described in scientific literature in 1975–1976. In modern crystal lore, green opal symbolizes emotional renewal, connection with nature, good luck, and heart-centered healing.

- It is mostly valued for its rejuvenating effect on the heart in an emotional sense, a comfort some people find supportive during recovery from sorrow.
Care and handling
Opal contains water, so it is best protected from sudden temperature changes, strong heat and very dry air, which can cause crazing or cracking. Clean it with a soft damp cloth and mild soap, dry it gently, and avoid ultrasonic cleaners, steam and harsh chemicals. Keep it out of long periods of direct sunlight, and store it wrapped softly apart from harder stones, because at 5 to 6 on the Mohs scale it scratches more easily than quartz.
Individual experiences with Green Opal vary, and its comfort is a matter of personal belief. Use it mindfully, hold it when your heart needs a pause, and remember that it complements, never replaces, caring human support.
