In October 1881. the illustrious scientist Benjamin Silliman Jr. was at the Torrance mine, Socorro, New Mexico -
Merry Christmas to all! The mineral baubles decorating the above tree are all from the same unusual American mine. The Christmas of 1902 was a corker for George B. Chittenden of Gila County, below (that's a contented smirk he's got) -
Analysis of a sample from the Moschellandsberg mainly consisting of malachite, calomel and minor eglestonite provided the evidence of a
new mercury arsenate from this locality: Chursinite.
As we have passed Thanksgiving and now moving into the Christmas festive period, you might want to indulge yourself in a box of chocolates to go along with the celebrations?
If so you might be interested in this listing from Norbert Stotzel starting today.
On the morning of the fifth of August 1898, a large rock entered the atmosphere over Maine, USA. Traveling at around 50 times faster than Concorde, it plunged from frictionless space into ever thickening layers of air. Atmospheric ram pressure began sharply braking the descent at around 50 miles above the ground, with the energy being dissipated by heating the air ahead white hot, and ablating the surface of the stone.
We are having quite a golden time for new mineral species additions to e-Rocks.
This short blog features news from from Jason Smith and Volker Betz regarding two new phosphate minerals from Foote Mine in North Carolina, USA. Apologies for the pun in the title.
The new minerals aniyunwiyaite and fanfaniite were discovered in a boulder in the dumps: when samples were analysed one proved to be triclinic, but with similar chemistry to kingsmountite.
In the current YourSystemmaticCollection (YSC) auction closing tonight, as well as the usual range of rare minerals there is another mineral first seen here on e-Rocks.
George was talking with Roberto Bracco of YSC at Munich and told us to look out for the mineral bonacinaite; Roberto was involved in the analysis and publication.
In November 1777 French botanist Joseph Dombey, above, set sail for Peru and Chile, as part of the joint Spanish-French Ruiz & Pavón Expedition. The arduous eleven year botanical exploration provided a wealth of plant specimens, an international incident known as the "Dombey Affair," and two minerals previously unknown to science.
Today (23rd October) we notched up item #680000 into our specimen database, completing another 10,000 increment to the catalogue.
The honoured rock is a specimen of Cleusonite from Fibbia, Ticino in Switzerland. The specimen was listed by Soenke Stolze of Nothern Minerals.
We covered the latest 10,000 step in 60 days averaging 167 minerals per day, as predicted a little faster than during the previous count.
Our daily sales rate in the same period has been ticking along at 140 sales per day.
It is Munich time again and I am sure you will have noticed a number of "Munich" themed auctions here on e-Rocks.
As usual there is a great choice of minerals coming up and more to come over the next week or so, there is also a full programme of auctions running during the show.
The Shinkolobwe radium mine, 1922. The Belgian mining engineer above is sitting on a 7 ton boulder of pitchblende. An immense quantity of gamma-rays is irradiating his gonads. Safety equipment, a tie and a pith helmet.
Here I am back in the office on a wet and dull Monday morning after the 2018 Bakewell Show. Having spent a “full on” weekend in the bosom of the UK mineral collecting scene I am feeling a little bit tired.
As usual George and I drove up to Bakewell from TV Towers on Friday afternoon to ensure we were there fresh and early for the Saturday start, plus indulge in the local (Chinese) cuisine the evening before!
Steverustite is a secondary mineral of copper and lead with an interesting and rarely occuring (in nature) thiosulphate anion (S2O3) within its structure.
Named after UK mineralogist and collector Steve Rust the mineral was first discovered at the Frongoch Mine, Ceredigion in Wales in 2008.
Steverustite is a supergene mineral formed through the oxidation of combined lead and copper sulphide ores.
Some interesting additions made to the e-Rocks catalogue from new seller Marco Frigerio of Classic Rocks and Gems, for both Iridium Chalk and Iridium Clay: these are examples of an iridium rich sediment found localised in unique layers in deposits spanning a certain age.
How the days and months seem to fly by, and now summer has passed we are into the autumn season of mineral shows. We start our outings as usual by visiting Bakewell show next week end.
Arguably Bakewell (Rock Exchange) is the UK's largest show for mineral collectors, it is the only one currently that is held over 2 days.
It is a great opportunity for mineral people to get together and we are again very much looking forward to it.
Here below are some details as given by the organisers - the PLMS.
In 1985 I had acquired some palladium metal, as a by-product of some illicit platinum reclamation I was undertaking. I made the above quarter-ounce "nugget" with it, drilled to be worn as a pendant.

Crystals to cosmetics, this post is about various minerals which have been used, without chemical alteration, as makeup.
Evidence of the use of minerals to adorn human skin has been gathered back to around 7000 years ago, although there is little doubt that the use of ochre could reach back to early paleolithic times.
Andyrobertsite and calcioandyrobertsite are two fascinating mineral species present in a single very famous specimen from Tsumeb. This superb specimen was featured in the cover of the Mineralogical Record vol.30, num. 3, May-June 1999, jointly with the original article describing these new minerals in the same issue (p.181-186).
Poudretteite, pronounced “poo-dret-tay-ite” is a rare borosilicate mineral first discovered in the 1960s but not formally recognised as a mineral until 1986 (IMA1986-028).
Named after the Poudrette family, original owners of the Poudrette Quarry where the mineral was first discovered.
Friday 24th August saw the addition of item #670000 to our listing database, marking another 10,000 specimens uploaded. This time the specimen was provided by TVM Auctions, a specimen of Strengite & Phosphosiderite from Bull Moose Mine in South Dakota, USA.
The latest 10,000 items arrived in 64 days averaging 156 minerals per day, achieved during the (Northern Hemisphere) summer when things are generally a bit quieter in the world of minerals.
Mineralogy’s greatest curiosity was not how Dr. John Woodward (1665 - 1728, above) obtained a pallasite meteorite for his collection, decades before the meteorite was actually discovered in Siberia….
Plinius Earth Treasures has started its official channel here on e-Rocks since December 2017, and one of the constants of the inventory was the listing of specimens from the Bruno Cerato collection and stock. Frequent e-Rocks customers will remember the specimens because of their rarity and aesthetics. It is time to pay a tribute to this Italian collector.
Bruno Cerato was a passionate field and mineral collector since his young age. He started collecting quartz in Margone (Val di Viù), tourmaline in the schists of Sant’Ignazio (Lanzo) and garnet in Val d’Ala.
After a short break we welcome back e-Rocks dealer – Jaroslaw Skupiewski, from Poland.
Under the banner Geo-Trader Minerals Jaroslaw has been establishing himself as an European show dealer for the last 12 years, but he has also been busy online.
Two more mineral firsts are on show on e-Rocks at the moment.
Our first specimen of fuettererite is due to close on Joy Desor's auction this evening.
For those who don't already know I have been an avid collector of antique bottles for nearly as long as I have been interested in minerals.
Time permitting I like to keep my interests alive by visiting the various "bottle shows" that run here in the UK.
