Properties of chrysoprase,physiological effects, zodiac signs and chrysoprase jewelry.
Chrysoprase is a greenish chalcedony variety.
It is the most valuable stone of the chalcedony group. The microscopic quartz fibres are arranged in a radial pattern. Nickel is responsible for its colour. The larger pieces have a slightly uneven colour distribution and are sometimes cracked. The colour changes with exposure to sunlight or heat, so special care must be taken when, for example, soldering is required when making a reservation.
Occurs mostly in serpentinite rocks and in the weathering of nickel ore deposits. Chrysoprase can easily be confused with jadeite, variscite and artificially green-stained chalcedony.
