New British Update 25 September 2020

25 September 2020

As another week draws to a close, we have a further exciting instalment of British classics from both the past and present. Hopefully, you will spot the odd one or two which have been eluding your collection, as we offer some quite historic and one-off specimens.

Although spoilt for choice, I must start with a simply fabulous “heart-twin” Calcite from the west Cumbrian iron mines, originally in the collection of William W. Jefferis (1820-1906), a famous USA collector, and complete with his label. This specimen measures 8.5 x 9 cm overall, composed of a large colourless Calcite twin blushed delicate pink and epitaxially joined with a smaller crystal displaying optical perfection! This specimen would grace any major natural history museum collection.

Another rare and spectacular offering is a good-sized classic Lady’s Slipper Siderite epimorph from Virtuous Lady mine, close to the delightful village of Buckland Monachorum in Devon. The epimorph’s surface is covered in scale-like saucer-shaped Siderite crystals which, close-up, look like a reptile’s scaly skin.

We also have a delightful arborescent crystallised Native Gold from Hope’s Nose in the Wellswood district of Torquay in Devon and a rare Botallackite from the intertidal foreshore by Cligga mine at Perranzabuloe. Botallackite is a rare copper oxychloride occurring as spectacular metallic bluish-chrome-green platelets covering granite.

Other great pieces include a large cabinet specimen of the rare borates Szaibélyite and Volkovskite from Boulby mine in North Yorkshire; a large and superb Kaolinite pseudomorph after two intergrown Carlsbad twin Orthoclase crystals from Goonbarrow China Clay Pit near St Austell, known as a “Pig’s Egg” and a magnificent polished slice of Cotham Marble, a fossilised Stromatolite of Rhaetian Triassic age of around 105 millions years old.

Like us, we hope you will enjoy and love this selection. A wander through these 21 items will at the very least provide a window to the diversity and beauty of British mineralogy and, better still, may enable fulfilment of a long-desired specimen on your wish list.

Here is what you have to look forward to in next week's updates:
