Fluorite

Here's an interesting cluster of inter-grown fluorite crystals made up of rounded cubes with inner fractures that criss-cross the faces. The crystals have a matte surfaces that sparkle under direct light due to a very thin druzy layer that coats them. The reverse side of the specimen shows how it was once connected to a long quartz crystal, you can see small smokey and mica crystals inside this quartz impression. The camera I used had some trouble capturing the colour, but it's a nice light blue/purple in-hand.
