Linarite
A variety of Linarite-chenite Group
What is Linarite?
Sometimes forming in large copper deposits, linarite's tiny crystals are only a minor copper source. This mineral bears a striking resemblance to Azurite and even occurs in the same places, so extra steps are needed for proper identification. No specimen has ever been found large enough to carve into a gemstone, but the raw crystal formations can make a stunning collector's piece.
Etymology & Origins
Linarite was first identified in 1822. It is named after the Linares Plateau, Spain.
Uses & Applications
Linarite is a minor ore of copper. Due to its rarity and softness, it is not commonly cut into gemstones or used for jewelry. Specimens are usually too small for practical applications and break easily. However, linarite is a valued mineral for rare mineral collections.
Healing Properties
Linarite is believed to provide emotional healing by releasing negative energy and allowing positive energy to flow through. It may help to relieve those who harbor guilt from past behaviors and allows for self-interpretation without blame. It stimulates the Throat chakra to assist communication and provides a calm, confident energy that enables the user to speak clearly and persuasively.

Key Characteristics
Formation of Linarite
It occurs in association with brochantite, anglesite, caledonite, leadhillite, cerussite, malachite and hemimorphite.
Composition of Linarite
Linarite is a somewhat rare, crystalline mineral that is known among mineral collectors for its unusually intense, pure blue color. It is formed by the oxidation of galena and chalcopyrite and other copper sulfides. It is a combined copper lead sulfate hydroxide with formula PbCuSO4(OH)2.
Health & Safety Information
- ⚠️Linarite dust is toxic because it contains heavy metals Copper, Lead.
- ⚠️Copper, Lead
- ⚠️It's advisable to handle linarite carefully to avoid generating dust and wash hands thoroughly afterward. When cutting or polishing linarite, wear a dust mask to prevent inhaling heavy metal particles. Store linarite 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.
