Malachite and Blue Sapphire Earrings

Malachite is a relatively soft stone (3.5 to 4 on the Mohs scale), so it requires a little extra love: Avoid Chemicals: Keep them away from hairspray, perfume, and household cleaners, as these can dull the polish of the green stone. Cleaning: Use only a soft, damp cloth. Do not use ultrasonic cleaners or steam.
