Al[(UO2)(AsO4)]2F(H2O)20
True power originates from the heart, with an open and fragile mind
Arsenuranospathite is an aluminium uranium arsenate fluoride hydrate — an exceptionally rare and structurally complex mineral. The formula contains twenty water molecules as an essential structural component, making the crystal highly susceptible to dehydration in open air. When it loses water it structurally alters, often visibly changing appearance — this is not degradation but metamorphosis. The aluminium-fluoride bonding adds unusual chemical character, placing arsenuranospathite in a small group of minerals that combine radioactive uranium, toxic arsenic, and reactive fluoride chemistry in a single crystal structure.
This crystal contains naturally radioactive elements and emits low-level radiation. Owning radioactive minerals may be restricted where you live — some countries regulate them strictly, with legal limits as low as 1 becquerel per gram. Check your local law before acquiring or shipping one.
All radiation safety comes down to three words: time, distance, and shielding. Handle a specimen only briefly, keep it at arm's length, and store it behind glass or lead. Enjoy it visually, or for energy work at a distance — never worn as jewellery, slept beside, or held in prolonged contact.
The chief practical risk is not the dose from the shelf but radon — a heavy radioactive gas that sinks and pools in low, unventilated spaces. Keep specimens well-ventilated, or sealed in a gas-tight container; with radon's 3.8-day half-life it never builds without limit and clears within weeks. Stored sensibly, the real dose is tiny — far below what people willingly absorb at a radon spa.
How dangerous are radioactive crystals really? Usually far less than people fear — and the science of low-dose radiation is genuinely surprising. Our full guide covers safe handling and storage, how to read a dose, the truth about radon, and the radioactive beaches and century-old healing spas where people seek radiation out on purpose.

Do not handle with bare hands. Do not allow to dry out in open air if avoidable. Do not crush or grind. Keep away from children and animals. Store in a humidity-controlled sealed container. Wash hands thoroughly after any contact.
Like other uranyl arsenate minerals, arsenuranospathite fluoresces strongly under UV light. The uranyl chromophore produces a vivid yellow-green emission — a reminder that beneath the visible softness of this crystal lies an extremely energetically active framework.
Arsenuranospathite dehydrates readily in open air, losing its twenty structural water molecules. This makes it simultaneously one of the most fragile and most hazardous minerals to store: the dehydration process produces structural change and may release fine particles containing arsenic and uranium compounds.
The presence of both aluminium and fluorine in the essential formula is rare among uranium minerals. This combination creates an unusually reactive structural chemistry — the fluoride bridges aluminium coordination polyhedra in a way not seen in related species, giving arsenuranospathite its unique structural identity.
This is a very powerful and extremely toxic crystal (because it dehydrates readily in the air) yet very fragile and caring as well. It has a hardness of 2 (on a scale of 1 -10). This crystal teaches you that real power and strength does not originate from the ego or with willpower but actually originates from the heart with an open and fragile mind.
Power Without ArmorThe paradox of arsenuranospathite is embodied in its physical nature: it is among the most powerful uranium minerals energetically, and among the most fragile physically. A hardness of 2 — softer than a fingernail — carries a frequency of 6 and a power of 7. The crystal teaches through this contrast: genuine spiritual power does not require hardness. The ego seeks to make itself impenetrable; true power flows through openness. To be soft, to be vulnerable, to have an undefended mind — this is not weakness but the most direct channel for real force.
"It is always the false that makes you suffer, the false desires and fears, the false values and ideas. Abandon the false and you are free of pain."— Nisargadatta Maharaj
At chakra 6, arsenuranospathite works primarily through the ajna center — the seat of perception beyond ordinary sense. With duration 6 and frequency 6, it sustains a clear, non-aggressive opening of the third eye: not a forced expansion but a gentle dissolving of the perceptual filters that the ego maintains to protect its constructed world-view. The caring quality noted in this crystal is real: it opens the mind not by force but by demonstrating through its own nature that fragility and power are not opposites.
