The hill was originally a "Sugar Loaf", outlying the North Yorkshire Moors. The geology is sandstone...
George pulled this out of a box in the warehouse and challenged me to make a decent spin of this. Black & white minerals are proving quite hard to photograph in the new box, this one has lots tiny detail and depth of field.

You may have noticed today's home page centre has changed; usually we display "today's auctions closing", but today we are showing "all auctions". There is a simple reason for this.
Because of demand from our sellers, we have had to increase our schedule...
Here is a tremendous specimen recently posted by Facebook friend and fellow collector Yasuichi Okazaki in Japan.
The specimen 37mm X 26mm X 46mm is primarily sphalerite crystals but intergrown with bright gold wires.
In his post Yasuichi goes on to...
Quite often minerals appear online from places that one is never likely to visit, some places like Tsumeb or Trepca are well photographed and beautiful, some of course ugly.
One place I have never visualised is the Tatra mountains spanning Poland and...

The story alleges that a local boy, on his way home from school, spotted the gem exposed in loose...
A little self indulgence here; not only is liroconite one of the "holy grail" UK minerals, it is one of my favourites!
This specimen listed by Carsten is small but exhibits excellent crystals, and is beautifully photographed!
Check out the other photos...
This amazing specimen of dolomite was collected today from the mines at Trepca in Kosovo.
Well known for its excellent common sulphide and carbonate crystallisation, I have never seen on like this before!
I found this petrified “hamburger” among the landscaping cobbles at my old house. It is a water-worn limestone rock that has a layer of fossilized creatures. We keep it on display in a McDonald’s container and bring it out for show and tell regularly....
We have fixed the problem with accessing e-Rocks yesterday.
The rescheduled end times for yesterday's auctions are now updated.
Note, these auctions will close across today and tomorrow along with the programme listings with altered times.
A couple of weeks ago we were contacted by a collector who had stopped collecting and was interested in moving his specimens on.
After completing a purchase last week and having been away in Bakewell all weekend, today was the day we had arranged to pick...
In the office this morning I worked out some interesting e-Rocks facts for the last year.

Also in 2016 we have served 629,183 visitors with 6.45M pages...
It is approaching the second anniversary of George joining the e-Rocks team; so after a record 24 consecutive "Employee of the Month" awards we thought it time to reward him with a nice trip to Spain.
The upshot to this will be that we are going to be...
It is that time of year again and I am sure you will have noticed a number of "Munich" themed auctions lining up on the schedule.
Suffice to say there have been some tremendous minerals coming through and still more to come over the next week or so, and...

The specimen itself comprises very rich crystalline cinnabar in quartz matrix, coming to us from old collection material from Germany.
Labelled simply as Grube Sizma, b....
It has already been quite a month, but today we passed another milestone with this specimen of bakhchisaraitsevite.
No it isn't the most unpronounceable mineral on the site, or the longest mineral name not to use a U or O, though it might be either!
Here we are back in Bakewell for the 15th consecutive year.
By comparison with others a short innings but one of the constants throughout the life and times of TVM.
George and I celebrated with a Chinese meal in the restaurant that used to be an Indian...
One more yellow sphalerite, this one from Spain, 18+ct "Markoh-i-noor" cut, best choice to boost the dispersion!

This really "unique" specimen of fluorite from Cavnic, Romania sold on e-Rocks a few hours ago for €805 (c$900).
Not only is the specimen pretty exceptional but also I believe it holds the site record for bidding extension.
As the bidding rules go, an...
Tomii Mine in Tochigi Prefecture, Honshu Island, Japan is quite well known for its quartz and amethyst clusters with crystals arranged in sprays around a central crystal.
This specimen recently posted on Facebook by Shigeki Nishimura in the Quartz group...

Greenockite from Tsumeb forms beautiful hexagonal orange crystals in cavities of Cd rich galena. Often the specimens host brownish Cd rich smithsonite. Crystal size is usually around 50-100µm.
Studies under the electron beam reveal the details of the...
As promised I took some pictures of the displays within the Mine to Mine Exhibition. If you are at Munich it is really worth going to see this.
This is not all the cases, or all the minerals within the cases shown, but hopefully gives and appreciation of...
Not well known for its mineral collecting Albania seldom figures as a source in many collections or available minerals.
In 9 years of e-Rocks we have only ever seen 2 specimens and localities.
The current specimen is a newly "discovered" combination of...
This excellent large specimen of smithsonite was one of a large suite of smithsonite in Warren Taylor's main Tsumeb collection.
The piece is a mound of flattened crystals pink in colour with an orange "cadmium derived" coating to the surface.
These amazing images recently appeared in the Journal of American Chemistry Society.
The picture shows individual molecules obtained by microscopy - the scale is mindblowing - 1 Angstrom length is 1 X 10-10m.
Amazing to see how the structures that have...
Love this photo posted by Megan Scott showing behind the scenes with e-Rocks seller Jason Smith, AKA Bucket of Holes Minerals.
Jason has been active on e-Rocks now since December 2012 and has been providing a super range of rare and interesting minerals...

We received a lead about the collection a few...
When I started examining micro minerals I came across a nice specimen hosting olive green bartelkeite. It was pure luck to find this mineral. This is what I can say now looking back at the small number of specimens I had.
This makes the species to one...
The project to open a pit to extract tungsten at Hemerdon has been going for a few years, but now it has entered into production with the first concentrate being produced.
As reported by the Plymouth Herald "it represents another major milestone in the...
Searching for radioactive minerals is a piece of cake compared to metal detecting. If you get a signal, you’ve got a target. None of this business of uncovering nails or shotgun casings, or the end of your steel-toed boot.
Still, using a mid-century...
As they say "you live and learn" and in the interest of mineralogy this is nearly a daily experience.
The photograph above shows some little grain-like crystals of native sulphur set on scorodite from Hemerdon Bal in Devon, UK. I have never seen these...

Size: H:4.8cm x W:4.8cm x D:4....
Our e-Rocks database is continuously growing and flexing as our sellers add new mineral types, varieties and of course the odd thing that we think is relevant to the naming of items on the site.
Recently I was adding a group of related "new" minerals,...

I collected the fluorite specimen above back in April 1996.
I remember it well from the events of the day before!
In those days I used to travel up from the South of England for weekend mooching trips in and around Weardale, usually arriving at the...
Life at TVM isn't all about swaning off to shows, buying minerals or photographing/describing things for our weekly lists.
All this activity leads to one thing: an untidy stock room. Usually we can survive for a few months before needing to tidy up. For...
Coming up to completion in today's Cartils minerals auction this specimen of obsidian from Douglas, Idaho, USA was designated item number 220000 in our catalogue when uploaded.

Our technical department at e-Rocks (AKA my wife and George) have been on at me for some time to get a decent mobile phone as I am usually hard to track down when offline.
Coupled with this we have a mobile version of the cataloguing/inventory system...
I was visiting an e-Rocks customer the other day, and was awestruck by his collection of radio-active artefacts.
Many things have changed over the years as learning and science have made our lives safer, but looking back some of these are just incredible...
Until I researched it I would never have thought vanadinite likely to occur at Ilfeld in Harz, Germany.
The specimen we discovered is a manganite matrix with tiny pockets of braunite, and with one solitary yellow (part) crystal within.
Being solitary and...
George uncovered this photogenic little millerite specimen last week and the picture caused quite a stir on Facebook over the weekend.
Labelled as being from the Windsor Colliery, Abertridwr near Caerphilly, Wales it displays a very pretty array of...
e-Rocks seller and Austrian collector Andreas Wallisch has been showing off a new addition to his collection.
A fine specimen of a variety of Lumachelle, called Bleiberg Shell Marble (Muschelmarmor)from Bleiberg in Carinthia in Austria.
Liroconite is just one of those minerals that attracts attention; it is rare, colourful and good specimens usually only found in old collections.
When a piece is listed on e-Rocks we usually get excited and this one is definitely no exception.
We didn't quite get to 50000 uploaded items during the first year of the "new" e-Rocks website, but we were very close!
Here we are 3 days later and courtesy of Volker Betz with a whitlockite specimen from Tip Top Mine, South Dakota, USA we crossed the...
As Facebook does, this fantastic specimen photo posted by Val Collins in May 2012 appeared in my timeline today.
Not many of these specimens of cerussite with pyromorphite from Daoping Mine appeared, this must be one of the best examples.
Above is a picture from a few days ago of our last pallet of minerals to arrive for 2016.
What a busy year it has been and now it is nearly over. Christmas and the holiday period are all set and there are some terrific contributions this year our...
George and I were discussing a mineral "anatolyite" newly added to the e-Rocks database, and couldn't find out who it was named for via the usual sources.
We know Anatoly Kasatkin very well, and through his involvement with systematic minerals and the...
The other week I was experimenting with lighting and rotation using tanzanite.
I managed to take these photographs - not much dichroism seen in the "rock tack"!
Carsten Slotta, of Mineral Treasure has this specimen of fluorite currently listed on e-Rocks.
From the lesser known Black Forest locality of Igelschlatt Mine, Waldshut the piece is covered in amazingly perfect hexakis-octahedral crystals.

As usual footfall is usually up along with the protective film on the carpets!

So goes the advertising strapline, and my reaction to seeing this photograph of gold bars, coins, nuggets and mineral ore/specimens.
The haul of 30,000lbs, approx 1.5 tonnes was recovered from the wreck of the SS Central America from deep of off the...
Great news from Thames Valley Minerals; we have just completed the acquisition of the final suites of specimens in the Warren Taylor mineral collection.

It is always interesting when a seller messages me because a mineral isn't listed on our main database.
Jason Boyd Smith, AKA Bucket of Holes made such a request for the mineral "Schmidite" yesterday.
Sure enough it was not listed with us, and further...
as the new site is online now and a lot to explore, i just want to give thumbs up for the e-rocks crew. Quite a task to manage all and fix the (inevitable) bugs which are quite usual if a system is relaunched or set up new. I am looking forward...
Having just been away for a fine week's stay at the village of Belstone, near Okehampton on Dartmoor, it was a neat coincidence that an auction selection coming through is from Belstone Consols Mine.
Whilst staying in Belstone I had already checked into...
Back in 2009 after Munich show I did a flit back to the Czech Republic to pick up a big consignment of Dalnegorsk minerals - some 40 flats. They are still going strong, here is a galena and manganoan calcite combination that came out this week.
Out for a run last night and listening to the radio, in particular an excerpt about Greek mythology being discussed by Stephen Fry.
Not my usual digest but it has been one of those weeks!
Anyway the piece was about Dionysus the Ancient Greek god of wine...
When we were at Bakewell Show last month, we bumped into someone we had not met before, Barry Taylor who also lives very close to us.
Barry is a collector at heart, but also runs an attraction called "Geology World" from his home in Chesham, Bucks.
