History

Azurmalachite is a natural stone that combines azurite and malachite. It's often banded and can be used as jewelry, decorative items, or as a wonderfully green and blue addition to any collection. The blue of the azurite dances gracefully with the bold greens of malachite. Intertwined, they form unique mineral specimens that are sought by those who desire them and prized by those who own them. This intriguing stone marries the deep greens of a dense forest with the brilliant blues of a northern lake. The colors present a cool and compelling combination. As the stones intertwine to form unique patterns, each piece becomes one of a kind. A 3 ½ - 4 on the Mohs scale, if azurmalachite is used in jewelry, it should be in a well-protected setting.
