Realgar on Ulexite (Rio Tinto Borax Mine, Kramer Borate deposit, Boron, Kern County, California, USA)
⚠️⚠️⚠️⚠️⚠️
Realgar is an important ore of arsenic, containing both arsenic and sulfur.
Its name comes from the Arabic rahj al-ġār, which means powder of the mine.
Most of realgar found comes from China, Peru and the Philippines. But this specimen, unusually, comes from California, USA.
Historically, it was used by firework manufacturers. For a long time, it was also used as a crucial ingredient in weed killer, pesticides, and rat poison.
Therefore, please leave this in its perky, and do not handle it with bare hands.
Ulexite is also known as TV rock and TV stone, because high quality versions have unusual optical properties. It grows as a silky, white crystalline mass of parallel fibres. We don't often see Ulexite because they are often ground up for the boron in them.

For every $15 spent, we will plant 1 tree to offset the carbon cost of mining, shipping and packaging crystals. These are real and natural products, and so might have some flaws or imperfections. We have done our best to pick the best pieces available, but nature is often imperfectly perfect. Therefore, please only make the purchase if you are alright with this.
