There is a whole case of superb fluorite specimens on display. I wish I could show them all!

An excellent orangey coloured, 8mm crystal of this rare cadmium sulphide is present in a vug in this matrix specimen from, I believe, Bishopton, Renfrewshire, Scotland.

Wonderful cubes of halite from Thuringia, Germany. Kind of looks like an interpenetrating twin but I don't think it is. The largest crystal is about 6.0cm on edge.

These are hauerite crystals! The octahedron in the middle is from Raddusa, Sicily and is about 4.5cm across.

Wow! A 30mm or so matlockite crystal in-on matrix. This is an amazing specimen. I did not write the locality down for this one but i believe it is a British piece. If anyone finds out differently, please let me know?

This is a rather fantastic example of molybdenite from an old Canadian Locality, Aldfield, Pontiac Co., Quebec. The molybdenite crystal is a tapered one that is about 70mm in greatest dimension. It was probably collected 100 years ago. Recently recovered specimens are up to perhaps 20mm in greatest dimension.

An exceptional old pyrargyrite specimen from the Harz Mountains, Germany. About 12.0cm across. It was probably collected over 100 years or so abo and so has lost all trace of redness, due to light exposure.
