Spooky Stones & Their Uses

It's scary season! Prospector is celebrating by sharing some of our favorite spooky minerals and metals from the team! Which is your favorite?


The earth is made up of several varieties of rocks and minerals, many of which are mined for their natural resources. Minerals aren't all gold and silver though, some of these stones have a bit more sinister uses! Let's take a look at some malicious minerals and learn a bit more about them!

1. Chalcanthite - This mineral may look pretty, but its water solubility can make its toxicity easily absorbed by plants and animals. General rule of thumb - don't lick the blue rocks.

2. Parisite - This rare mineral may sound scary, but it is actually named for J.J. Paris, it's discoverer. It was originally found in the Muzo emerald mine in Colombia, but varieties are also found in Sweden and Colorado.

4. Arsenopyrite - this mineral is similar to pyrite (aka Fools Gold), but with one deadly difference: the addition of arsenic to its chemical makeup. Heating this mineral will give off a strong garlic odor, which is a warning sign of a toxic arsenic vapor.

5. Hutchinsonite - This mineral is a mix of thallium, lead, and arsenic. Long term exposure to thallium includes hair loss, sickness, and even death. This mineral is found in mountainous regions of Europe, often in ore deposits.

6. Chrysotile - This mineral is the most commonly encountered form of asbestos. The fibrous nature of this mineral allows tiny pieces to become airborne and inhaled, then embedded in the lungs causing scarring. Asbestos was banned in 1989 in most products, including building materials.

7. Orpiment - This mineral is made up of arsenic and sulfur, making it very chemically reactive. The minerals may look pretty, but holding them may release a deadly powder and garlic smell. Historically this mineral was used on the tips of arrows to poison enemies, but it was also used in ochre paint.

8. Cinnabar - This gorgeous red mineral should be admired, but not touched! It's name means dragon's blood, and it is the main ore for mercury. It can release pure mercury if disturbed or heated, which can cause tremors, loss of sensation, and death. The history of Cinnabar varies, as it was used for decoration and carvings, but also for healing powers by ancient medical practitioners.

9. Sodalite - This mineral is a tectosilicate with royal blue varieties, and is often used as an ornamental gemstone. While it isn't toxic, it does tend to fluoresce a spooky orange color under UV light!

10. Galena - This mineral is an important source of lead and silver and it has a low water solubility. However, weathering of the mineral can release lead chich can cause cardiovascular disease and developmental problems in children. It is also fairly brittle, and cause lead dust exposure.
