What is native arsenic?
Native arsenic is the elemental mineral As. It is uncommon as well-formed crystals and is more often found as massive, granular or botryoidal material associated with arsenic-rich hydrothermal ores.
Mineralogy and structure
Arsenic is a native element with a trigonal structure in its common grey form. Mohs hardness is about 3.5-4 and specific gravity is high, around 5.7. The mineral can alter at the surface and may develop coatings.
Colour and appearance
Fresh material is tin-white to grey with a metallic lustre, but tarnish can darken it to black or dull grey. The streak is dark, and crystal form is less common than compact or botryoidal aggregates.
Formation and localities
Native arsenic forms in low-temperature hydrothermal veins, often with realgar, orpiment, arsenopyrite, silver and other sulphides. It is known from Germany, the Czech Republic, France, Morocco, Canada, Mexico and several Asian ore districts.
Collection and handling
Arsenic-bearing minerals are display specimens only. Do not cut, grind, heat or use them in jewellery, avoid creating dust, wash hands after handling and keep them away from food and children.
Arsenic and zodiac signs
In popular birthstone and zodiac guides, Arsenic is often associated with Scorpio and Capricorn. These zodiac crystal associations are part of modern spiritual culture and vary between traditions, countries and individual practitioners. They are not a mineralogical classification and should not be presented as a scientific property of the stone.
Esoteric meaning of Arsenic
Crystal collectors and readers of esoteric symbolism may choose Arsenic for its colour, texture, locality and personal meaning. In crystal healing and meditation traditions, it may be described with themes such as focus, grounding, protection, calm or confidence, depending on the source. These symbolic interpretations can be useful for storytelling and personal reflection, but there is no reliable scientific evidence that a mineral changes health, energy, luck or destiny.
Choosing Arsenic as a birthstone or symbolic crystal
When choosing a Arsenic birthstone, zodiac crystal or spiritual gift, compare the actual specimen: natural colour, crystal habit, transparency, inclusions, locality and condition. A mineral guide is more reliable when symbolic associations are kept separate from tested physical properties and from the description of an individual piece. Because Arsenic may contain toxic or radioactive elements, it should remain a display specimen and should never be cut, polished, used in jewellery or treated as a wellness product.
