Adamite
A variety of Olivenite Group
What is Adamite?
Due to imperfections while forming, adamite can display a magnificent array of colors that are cunningly disguised in a russet-colored rocky cloak. It is rich in zinc but is more sought after by crystal collectors than ore-seekers. The most stunning examples of adamite have been found in Mexico.
Healing Properties
Adamite activates and aligns the Solar Plexus and Heart chakras to unveil the inner dreams and desires of its user and to help them discover ways to pursue those dreams. It is said to reconnect the body to the mind, bringing a sense of balance and harmony between the two. Its energies may influence chemical imbalances in the physical body and help to restore energy.

Key Characteristics
Formation of Adamite
Adamite occurs as a secondary mineral in the oxidized zone of zinc- and arsenic-bearing hydrothermal mineral deposits. It occurs in association with smithsonite, hemimorphite, scorodite, olivenite, calcite, quartz and iron and manganese oxides. The yellow to bright lime-green colored crystals and druze along with its distinctive fluorescence make adamite a favorite among mineral collectors. Found in Mapimí, Durango, Mexico; Greece; and California and Utah in the United States. Adamite was named after the French mineralogist Gilbert-Joseph Adam (1795–1881). It was first described in 1866 for an occurrence at the type locality of Chañarcillo, Copiapó Province, Atacama Region, Chile.
Health & Safety Information
- ⚠️Adamite dust is toxic because it contains heavy metals Arsenic, Copper.
- ⚠️Arsenic, Copper
- ⚠️It's advisable to handle adamite carefully to avoid generating dust and wash hands thoroughly afterward. When cutting or polishing adamite, wear a dust mask to prevent inhaling heavy metal particles. Store adamite in a sealed container in a well-ventilated area, away from children and pets. For those involved in crystal healing, never put it in your mouth.
