Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2 It belongs to the halide minerals It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon Mohs scale of mineral hardness, based on scratch Hardness comparison, defines value 4 as Fluorite
Platinum is not an ancient metal; it wasn't until relatively modern times that Platinum was regarded as such a valuable commodity In fact, before the 1700's, the identity of Platinum was uncertain, and Platinum was often regarded as a lesser form of Silver The extremely high melting point of Platinum also made it difficult to melt down and .
Painite Visible Spectra (380 - 1100 nm) Painite was once considered one of the rarest minerals on earth The first painite to be recognized as new mineral (painite #1) was a sample discovered in Burma in the early 1950's For many years only two crystals of this hexagonal mineral were known to exist Its chemical formula is ideally: CaZrBAl 9 O .
Platinum is a very different substance to a chemist Platinum metal is silvery white and does not oxidise, properties that make it highly appealing for jewellery It is more precious than silver but with prices more volatile than gold
