Like Cornwall, a classic location. So let's hope we get lots of good photos from this county. I used to go there as a child, but was too young to collect much.

Two old classics from Devon


1-shorl.jpg
 Description:
Schorl
Woolley Farm, Bovey Tracey, Dartmoor & Teign Valley District, Devon, England, UK
45 mm

A British classic, schorl tourmaline from Woolley Farm.

These tourmalines were collected between about 1810-20
 Viewed:  25134 Time(s)

1-shorl.jpg



1-beeralston2.jpg
 Description:
Fluorite
Bere Alston, Bere Ferrers, Tavistock, Devon, England, UK
Crystals to 20 mm

A fluorite with much history, from an unnamed Bere Alston mine.

This specimen, with crystals to 20mm, was probably collected in the early 1800s. It had been owned by three people who had minerals named after them and was once on display at the American Museum of Natural History in New York.

Originally in the collection of Clarence Bement (1846-1923) , for whom bementite is named, his collection, said to be "the finest collection of minerals ever made" was purchased in 1900 by financier J.P. Morgan (beryl var morganite) and donated to the AMNH. There is a black arrow on the underside (painted on all display specimens) to guide staff in what the then curator, Louis Gratacrap, believed was the correct orientation for display.

Traded out of the AMNH, the specimen was subsequently in the collection of Dr Richard Hauck (hauckite).

An identical but larger specimen was included in the partial disposition of the Philadelphia Academy Collection suggesting that they formed part of a single pocket.

Hi Ru,

re: your 'Larger Devon baryte' ( https://www.mineral-forum.com/message-board/viewtopic.php?p=32209#32209 ) - I had a look at 'Minerals of Cornwall and Devon' by P.G.Embrey and R.F.Symes; a B.M.(N.H.) publication. About the quarry at Babbacombe, near Torquay, the only reference I could find was on page 60, which states the quarry '' produced specimens of pink cockscomb baryte that are represented in many old collections.''
Not big yellow/orange tabular crystals like yours!

However, on page 85 there is a photo of large orangey tabular baryte crystals to 5cm, which came from Wheal Mary Ann, Menheniot, Cornwall. I wonder if this is the origin of your specimen...

I must confess minerals from SW England aren't my forte; maybe someone more knowledgeable than me can come in on this ?

Regards, Mike

Wonderful fluorite story, Ian.

Strange and fascinating topaz, Mike. Did you collect these yourself?

I'll be very interested if anyone has more information on the big golden baryte crystals. Browsing, I see a specimen with fairly similar, but far smaller (3 cm) terminated crystals from Petit Tor, Babbacombe. I am also no expert on minerals from that part of the country.

Thanks Ru, I did collect them, over ten years ago, from a sea-level locality on the island.

Mike,

Great transparency and beautiful and interesting termination on your Topaz on Quartz from Lundy (013).

Thanks Don, it's kind of like some I've seen (IMG_0691.JPG) from Yuno, Shigar Valley, recently... maybe that's why I posted it ;-)

Also, your fine beryl (var emerald) specimen (1-IMG_0756.JPG) from Rist Mine, Hiddenite, Alexander County, North Carolina, USA: reminded me of a beryl (var aquamarine) specimen I have ;-)

Mike,

In my estimation finding this aquamarine yourself makes it extra special.

Don

Thanks Don and Ru, it is a rather special aquamarine. Of course the photo shows it off well; it doesn't look that good in real life... amazing what a bit of mood lighting can do !

The Lundy topaz specimens probably come from a tiny old quarry called VC quarry. My specimenfrom there also has small beryl crystals associated.

Devon - something old, something new. A classic "ladies slipper" from the early 1800s and a topaz collected at the end of the 20th C

More from Lundy.

These three single crystals were found together, loose, in a fist-sized cavity which was full of a white clay-like mineral (kaolinite ?). They were the only objects found in the cavity !



2009_0118Recent-specimens0029.JPG
 Description:
Topaz
Lundy Island, Devon, England, UK
11mm x 9mm x 7mm
Lustrous, undamaged, transparent colourless topaz crystal. The tiny 'dimples' on some of the termination faces have a square appearance, so it could be the topaz was host to tiny fluorite crystals at one time. Fluorite occurs in the vicinity in small amounts; as it also does at the VC Quarry.

Those are great pieces from Lundy Mike, better than I managed. I got mine when I was over there for a weeks climbing some years ago. Managed to sneak in a few hours collecting and meant to go back to do some more, but still haven't.

Thanks Ian, I didn't know you were a climber. Yes I have also been thinking about going back to Lundy sometime, but haven't got around to it yet.
In the meantime, for those who don't know what Lundy looks like, this photo may give an impression... ; )
Cheers, Mike

Great picture Mike, there was a basking shark just off the bottom of the slab when we were there.

We did The Devil's Slide, Satan's Slip and Albion on the slab and a host of great routes elsewhere. Some of the best climbing in the south-west.
