CheMically, malachite is a copper carbonate hydroxide. It is a mineral that usually forms coatings, needle-like crystals, or solid botryoidal aggregates with a layered structure. In ancient Egypt, cameos, amulets, and other decorative items were carved from it, and crushed malachite was also used as a pigment in painting or as a cosmetic. The offered stone comes from Congo.

Uniqueness of the stone: An opaque piece with typical green shades that can range from lighter tones to black-green. The vibrant coloration elegantly complements the subtle striping.

Limitations: Malachite is dissolved by most acids. The stones are hand-polished and very soft, so there is a risk of mechanical damage.
