General Information
Malachite is especially fragile. Protect malachite from scratches and
sharp blows. Also avoid large temperature changes (such as leaving it be
a heater vent or in a hot car). Do not clean malachite in a home
ultrasonic cleaner. Washing malachite in water will remove its finish.
Malachite is always coated with a protective polish. This polish will
wash off. Imitation malachite has very regular black or white banding.
