Very sexy indeed, Jordi. I am surprised that this one got past the censorship committee ;-)

An old, large Fluorite from Wheal Buller, Cornwall - trying to clean this up but don't have a needle water jet tool - I would love one!. It was found in a low Cornish hedge/wall at the site, in 1988. A bit rough, but a significant piece.

Locality: | Wheal Buller, Redruth, Camborne - Redruth - Saint Day District, Cornwall, England / United Kingdom | |
|
Dimensions: | 14.5cm x 12cm |
Description: |
An old 'gnarly' piece that used to be disfigured by some kaolinite/sericite(?), still has annoying 'flecks' as you can see. |

Great contributions to this thread, guys!
Jose: A really good idea to make a stereo photo, I always love to see this kind of 3D-pictures.
Jesse: As usual, your fluorite specimens are a pleasure to view, especially the one from East Pool Mine.
Jordi: I think no further comment on the "sexy" chalcopyrite is needed, for it now has its own thread ( https://www.mineral-forum.com/message-board/viewtopic.php?p=56989#56989 ) ;-)
Mark: Interesting fluorite from Wheal Buller, reminds me of some several fluorites from Germany (Bavaria and Saxony).
James: Great bournonite specimen - and painting.

Mark, great to see new specimens being added. Do drop me a message (PM) if the locality you want to use does not exist, as I manage the database of UK localities.

A rare specimen of Almandine(?) Garnet from pegmatite at Megilligar Rocks, Tremearne Cliff, Porthleven, Cornwall (from the back-beach exposure). I am informed it is dodecahedral in form, though this is difficult to make out in the image. In Cornwall, Garnet in pegmatite is virtually unheard of.
Mineral: | Garnet with Fluorapatite on Orthoclase |
Locality: | Megiliggar Rocks, Tremearne, Porthleven, Cornwall, England / United Kingdom | |

Dimensions: | 3cm x1.4cm |
Description: |
FOV 3cm - (there is also some lithium-mica and lollingite). |
