Fuchsite Stone Meaning and Properties
Fuchsite | Radioactive Mineral
Fuchsite is a variety of chromium rich muscovite which is the cause of this stone's distinctive green colour. The more chromium that's present the stronger the colour and in some cases it can even be similar to emerald. When replaced by aluminium the shade of green becomes distinctively lighter.
This radioactive mineral fluoresces lime green under ultraviolet light which is due to the presence of potassium. Fuchsite can frequently be found as tiny mineral inclusions within certain rocks but when present in large quantities it becomes known as verdite. This stone tends to be used for lapidary purposes.
Fuchsite is a relatively soft stone that's rarely found with good purity. It grades 2 to 3 on Mohs scale of mineral hardness and often features inclusions of red corundum otherwise known as ruby. Ruby in fuchsite as it's correctly known if often mistaken for ruby zoisite which is much rarer and considerably more expensive. Ruby zoisite is much harder than ruby in fuchsite and more often than not will also exhibit visible crystals of black hornblende.
Frequently misspelt and mispronounced, fuchsite was named after German chemist and mineralogist Johann Nepomuk von Fuchs hence is correctly pronounced fook-site.
