Calcite, Hematite, Aragonite and then all the minerals from Caldbeck fells. This one is going to be great fun. So let's start with another specimen In the Sedgwick museum Cambridge (it is a tiny display but has a few good UK specimens)

I was just reading (*) about Norman Thomson's first collecting trip to Roughton Gill Mine, by bicycle, in 1939, when the dumps were "covered in green and blue." He later built a vast collection of minerals from the area, many of which (1700) were donated to the Oxford University Museum of Natural History in 2010.
The diversity of mineral species from this area is very large, many of them green or blue in colour. What interesting material do people have?
Some green pyromorphites to start with.

Thanks Mark.
I'm looking forward to seeing the specimens people have from those hills. Just sticking to blues and greens, there will be plumbogummite, brochantite, philipsburgite, adamite, rosasite, duftite, beudantite and perhaps a few more.

Plus the famous blue hemimorphites and perhaps some pseudomalachites.

Wow, Knut, an astonishing and beautiful specimen.
An excellent hemimorphite, Ian, and it definitely adds to the interest when a historically well known collector is involved.
Lovely image of Roughton Gill pyromorphites, Jordi.
I just put a group of Caldbeck specimens together for a photo.

Here's some ... Bayldonite, Caledonite, Linarite, Malachite, Plumbogummite, Pyromorphite, Rosasite and Apatite. I was surprised how many green and blue Caldbeck samples Ive got, and theres quite a few more Ill add when I get the chance, some are really just locality specimens but theres some good ones lurking in there too.

Hi Nurbo. I really like this combination. plumbogummite.jpg. It is stunning. I never knew that the UK had such nice mineral specimens.

Hi Pierre,
Unfortunately the really nice UK pieces are hard to come by,and whenever I see them I realise that unfortunately I'd need to sell my house to own one.
The Scorodite is greener in the flesh than the photo suggests.

Excellent selection of specimens, nurbo. Thank you for sharing them. I had forgotten about the apatites (have you seen one with good terminations?) and had not seen scorodite from there before.
