💫 Green lore and care
Chrysoprase is not simply any green chalcedony. The name is properly associated with nickel-coloured material. Chromium-coloured green chalcedony is usually called Chrome Chalcedony, while “Lemon Chrysoprase” commonly refers to nickel-bearing Magnesite rather than quartz.
Chrysoprase measures approximately 6.5–7 on the Mohs scale and has no cleavage, although sharp impacts can still chip it. Clean it with lukewarm water, mild soap and a soft cloth. Avoid harsh chemicals, prolonged high heat and intense sunlight, especially when dye, resin or other treatment is uncertain.
