Fluorite with Nickeline and Potassium Feldspar (Palmbaum Mine [Shaft 46], Gehringswalde, Wolkenstein, Erzgebirgskreis, Saxony, Germany)
This specimen comprises of very lustrous yellow cubes of fluorite with tiny red hematite speckles freckled all over.
The matrix on which the fluorite sits an interesting one. It has a mix of coral-pink potassium feldspar, and a strip of nickeline - that's a new one for us!
Nickeline was initially named Kupfernickel in 1694, after Satan or Nick (which, in Germany, was the name of a mischievous deceiver). This is because it looks very much like Copper, but actually yields none.
It was later renamed Nickeline in 1832 for its nickel content (Chemical Formula: NiAs). Some others call it Niccolite, from the Latin Niccolum.
For all of you who still remember secondary school Chemistry, yes, that's Nickel-Arsenic. It is toxic ⚠️⚠️⚠️⚠️, so please wash your hands immediately after handling this piece.
