Anglesite
Anglesite – a rare collector's mineral with an adamantine luster
Some minerals are abundant, and finding them in the wild is no great problem – if you know where to look. With some minerals, however, finding them is almost a miracle. One of these rare minerals is anglesite – a transparent lead sulfate with an adamantine luster whose beauty will amaze every collector.
- The most beautiful anglesite crystals are considered to be those from southern Sardinia and Tunisia.
- In the Czech Republic, anglesite has been found in Zlaté Horyand around Jihlava and Příbram.
- In Slovakia, around Banská Štiavnica.

Although anglesite is very beautiful in its natural form, it is not suitable for the jewelry industry. It is not hard enough and contains lead, which is toxic to the human body.
Natural lead sulfate
From a scientific point of view, anglesite is a natural compound of lead sulfate. It occurs in several color varieties – the crystals can be colorless, yellowish or brilliantly lustrous, and always transparent. Individual crystals intergrow, creating fascinating natural formations. Anglesite does not dissolve in water or alcohols, but it dissolves well in nitric, hydrochloric and sulfuric acid.
• Important safety notice:
- Anglesite contains lead – it is not recommended to wear it in direct contact with the skin.
- It can be toxic to the human body – handle it with care.
- It is not suitable for jewelry because of its low hardness and toxicity.
- Keep out of reach of children.
Uses of anglesite
Anglesite is valued mainly as a collector's and decorative mineral. Its transparent crystals with their adamantine luster are a stunning example of what nature can create. It is a beautiful addition to a mineral collection or a decorative element in an interior – similar to, for example, barite or vanadinite, which are also valued more for their visual beauty than for esoteric properties.
A final curiosity – crushed anglesite was once used as an additive in theatrical makeup. Mixed into greasepaint, it stopped it from drying out – although, understandably, it did not do actors' skin much good.
