Gem care:
Malachite is soft and sensitive to both heat and acids. It demands gentle care. Ultrasonic cleaning methods are not recommended. It is a porous gem that may absorb liquids that can affect its color and erode the stone.
Constant wear is not advisable for malachite jewelry. It can be used in earrings, brooches, pendants, and tie pins without facing any special problems.
To clean your malachite, simply use soapy water and a soft cloth. Be sure to rinse well to remove soapy residue.
