British Classic Mineral Specimens


Invitation to open days

If you would like to drop into Campylite HQ, please drop us an email. We are currently sorting out the collection, and have available a considerable number of duplicate and surplus specimens - mostly northern english pieces. The only way to truly appreciate the extent and quality of these is to arrange a visit, when we have great coffee, our own cider, and home baked cakes!

Welcome to the new site!

Finally we've finished work on the site - so here is the nice, shiny new I'll start uploading photos and minerals over time, so keep an eye out for some nice specimens, both to view, and to buy. Some of the Greenlaws team are in Tucson right now, but Pete is focussed on maintenance work at the mine, and starting some technical articles..

Munich Show 2023

We were finally able to attend Munich again, after an absence of several years due to Covid. We were asked to be part of the Special Exhibition, in which famous mineral specimens and their paintings were featured in an incredible gallery. My best campylite specimen appeared, together with a magnificent calcite from West Cumbria (formerly in the collection of Wayne Leicht) and one of the best 'funkies' from Greenlaws mine. The artist - the amazing Christopher Smith-Duque. Together with our...

First cavity of the year - washing out...

Adam Pacey - researcher at the Natural History Museum takes control of the pressure washer to help open up a cavity containing huge clusters of purple fluorite crystals. Adam is rendered almost speechless at the size of the cavity and associations - huge galena crystals abound. With me is Sam Capstick, on only his second underground trip, and again rendered almost speechless at what he is seeing. It is a privilege to see this sort of thing, and I can't think of a nicer couple of guys to be...

Opening up the mine - first cavity of 2016

First video of the weekend - cleaning out a large cavity with Adam Pacey, who is undertaking research at the Natural History Museum in London. Its a privilege to have such expertise down our little mine, and to see his enthusiasm for the mineralogy:

Greenlaws Collapse Cavities

This is the best photo I've seen to date of one of these huge Greenlaws 'collapse' cavities. Taken by Adam Pacey at the weekend, it shows a partly washed out cavity, with rubble at the top, clay in the middle, and groups of fluorite specimens both on the floor, and in the middle, which have fallen off what was once the roof before a second phase of fluids dissolved the wallrock and allowed the crystals to drop.

If you look carefully at the end of the cavity you will see crystals facing both...
