ANGLESITE – Large Lustrous Crystals, Broken Hill Mine, NSW, Australia

This is an outstanding, completely natural Anglesite specimen from the world-famous Broken Hill Mine in New South Wales, Australia, one of the richest silver-lead-zinc deposits ever discovered. The piece shows a well-developed crystal growth that allows the collector to fully appreciate its cristalline forms: the individual crystals present sharp, well-defined edges and bright, reflective surfaces that catch the light beautifully from multiple angles, giving the whole specimen a lively, almost glassy appearance typical of fine anglesite from this locality.

What truly sets this piece apart is the impressive size of its crystals, which lends the specimen a strong three-dimensional presence and a remarkable visual impact rarely seen in smaller examples of the species. Broken Hill has been mined continuously since its discovery in 1883, and while many of the original underground workings that produced classic oxidized-zone specimens like this one have long since closed, the line of lode remains one of the most historically significant mining districts in the world, and material of this quality is becoming increasingly difficult to source on the current market.

A genuinely eye-catching natural sculpture, this specimen is equally suited to a serious systematic mineral collection or as a striking decorative piece in a refined interior setting.

Anglesite is a lead sulfate mineral (PbSO4) that forms as a secondary mineral in the oxidized zone of lead ore deposits, developing when primary galena is chemically altered by oxygen and water percolating through the weathered portions of the orebody. In its pure form, the mineral is essentially colorless to white, since lead and sulfate ions do not act as chromophores; any tint occasionally seen in anglesite from other localities is generally caused by trace impurities trapped within or on the crystal surface rather than by the mineral species itself. The crystals typically show a bright, adamantine to vitreous luster on well-formed faces, which is what gives fine Broken Hill specimens their notably brilliant, reflective appearance.

Anglesite crystallizes in the orthorhombic system, commonly forming tabular or short prismatic crystals with well-developed pyramidal terminations. Broken Hill, discovered in 1883, is one of the most important lead-zinc-silver deposits in the world, and while many of the original underground workings that produced the finest oxidized-zone specimens are now historic and no longer active, the broader mining district has continued operating in various forms for well over a century.

• Formula: PbSO4
• Key chemical elements: Lead (Pb), Sulfur (S), Oxygen (O)
• Hardness (Mohs scale): 2.5 - 3
• Mineral class: Sulfates
• Crystal system: Orthorhombic
• Crystal habit: Tabular, prismatic, with adamantine to vitreous luster
• Formation: Secondary mineral formed by oxidation/alteration of galena in the weathered zone of lead deposits
• Color: Typically colorless to white; occasional tints in the species are caused by trace impurities rather than a structural chromophore
• Locality status: Historic underground workings largely closed; broader Broken Hill mining district active for over a century

Broken Hill, discovered in 1883 by stockman Charles Rasp, sits atop one of the richest silver-lead-zinc orebodies ever found on Earth, and its long mining history has made it a legendary source of fine secondary minerals for collectors worldwide.

Anglesite forms in the oxidized, weathered portions of lead deposits, where it develops as galena (lead sulfide) is gradually altered by oxygen and water into lead sulfate. Because of this, some of the finest anglesite crystals from Broken Hill were historically found closely associated with cerussite, another oxidation product of the same original galena.

In crystal healing traditions, Anglesite is considered a stone of mental clarity and inner focus, believed to help dissolve confusion and support clear, structured thinking. It is also associated with grounding energy, said to help its owner feel more anchored and centered during periods of change or stress. Some practitioners use Anglesite to encourage patience and a calm, methodical approach to problem-solving.

As with all crystal healing practices, these interpretations are not scientifically proven.
