He is also the first Dealer to put his e-Rocks auctions on his website using our Page App.
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"!
A very early start from TV Towers, to Heathrow and onto the short flight to Munich.
Really it is a very easy journey and a good time for George and I to catch up on business and plan for the next few days.
The view of mountains of Bavaria as we came into...

Most people in tuned into the news will be aware of the media splash behind the launch of the new Apple iphone X (and 8) the other day.
It has been widely publicised that the X phone was to...
Once again whilst researching and updating a new mineral I came across another interesting figure behind the mineral name.
This time the mineral was gorbunovite - the citation from the IMA proposal is in the box below.
The mineral is named...
Sapphire - September's Birthstone
Sapphire - Zazafotsy, Ihosy, Madagascar - 16mm, sold in September 2018
We have not written a "numbers" blog for nearly a year; we figure most people are here for the minerals but sometimes it might help to find out...
Saturday morning, September 2014, we were up bright and early and on the road to Fernleigh, Ontario. Unless you are a mineral collector, you likely will not have heard of the it.
We were looking for a kyanite and staurolite occurrence. Actually, I was...
I was working on a new mineral the other day and spotted an interesting question raised shared by various sources.
Tredouxite (IMA approved pending publication) is named for professor Marian Tredoux in the Department of Geology, University of the Free...
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...
Here we are at the 2017 Bakewell Show, and what a day it has been.
Having stayed overnight in town last night we started the day early in the main "gymnasium" hall and straight into the business of looking at minerals and meeting people.

A little bit of excitement for a new discovery/identification of bazzite in the Western Alps, Piedmont, Italy.
Usually highly sought after by collectors, bazzite is a rare scandium rich type of beryl usually small with a charateristic strong baby blue...
You know you’re a rockhound when cries of “Froodite! I’ve got froodite” are heard echoing from the rafters. And before you step back in alarm, it’s not contagious… it’s the name of a mineral.
Please, allow me to make introductions. My husband Reiner and...
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) -
But not so, the...
The Hampshire Mineral & Fossil show is on Saturday 5th September at its usual venue in Lyndhurst Community Centre.

We are looking forward to being there as a guest of/helping with Christian Rewitzer in Hall A6.551 - the usual place.
We will be there from Wednesday 28th October to close time on 31st October.
Mineral photography continues to be well written up in many places, and no doubt will get a few mentions here from time to time; we do have one or two expert photographers selling and contributing to our pages.
Personally we have photographing minerals...
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,...
In terms of desirability, the specimens collected by NASA in ‘69 would be hard to beat. Their superb provenance is excellently documented. They are holotypes of three minerals new to science, and brave men risked their lives to collect them.
It is already nearly a few months since we returned from our eventful trip to Alicante with the Uerpmann collection; when we returned we parked a large portion of the unseen collection in our warehouse.
All this material had been wrapped and taped in...
Back in 2009 the late Paul Lowe was disposing of the mineral collection of the late Dr Fred Armitage.

The specimen 37mm X 26mm X 46mm is primarily sphalerite crystals but intergrown with bright gold wires.
In his post Yasuichi goes on to...
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...
Congratulations to long standing customer of e-Rocks, Andy Christy for the naming of new mineral "andychristyite" after his good self.
Andy joins an ever growing list of sellers, customers and visitors to our site to which this honour has been bestowed....
Sometimes even the most clearly labelled specimen will have you scratching your head in trying to find out what it is or where it is really from!
Working with old collections and labels it is possible to encounter changes in mineral names via...
Last month we blogged about the acquisition of an important Wheal Maudlin "Horsetooth" siderite specimen from an unspecified lot of minerals at an auction in North Yorkshire.

After Wesley's death...
If you don't already know about it, here is a website for anyone who is interested in old mining history, especially related to the western states of the USA.

It was down to Carsten to wrap up August 2015, and boy did he find something a bit unusual!
Brunogeierite is an insanely rare iron germanate found only (so far) in a few places, plus Tsumeb. The crystal habit is black octahedral crystals.
For a Tsumeb...
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.

Not really a new year's resolution as such, but to make space for new projects, it is time to sell my old collection/hoard of Romanian minerals.
Back in the day, before 2002 I put together quite a large selection of Romanian pieces, traveling there when...
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...
Earlier this month I was introduced to a small selection of specimens of talc on dolomite from Portreath Beach on the Lizard, Cornwall.
These came to prominence in the Mineralogical Record Show Report for Ste Marie 2017, written up as quote.

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...

We continue to use our page to provide our Facebook followers a daily snapshot of the e-Rocks site new listings,...
Flicking through the auctions yesterday I spotted a specimen of Mineevite-(Y) - always inquisitive to see the composition of these more obscure minerals I looked at the mineral data.

I have always loved the place and the mining and mineral heritage have created an enduring strange feeling of home from home when ever I visit.
The central purpose of my...
Whilst sorting through some Tsumeb minerals recently we came across this label, with the dealer information cut off.
All we had to go on was the hand writing and a "crossed hammers" symbol on the left.
With a little help and research we have traced this...
Well not really, but as things have quietened down a bit in the week since launch it seemed a good opportunity to display a few minerals myself.

Along with everything else that is going on we have been doing some background work on some phosphate minerals spurred on by a request by seller Modris Baum (LMB Minerals) and something he had discovered on a Brazilian hureaulite specimen.
A lot earlier this morning George and his partner Sam became parents for the first time. Their little boy has been named Alexander Thomas Wrigley.
There are two knock on effects, I have become a grandparent, and George is now currently covering his new...
March Oxford show is the first of the 2016 series of Oxford shows.

Personally suffering from "Manflu" I...
The Italian town of Larderello was created to exploit the mineral riches of boraciferous fumaroles. Its chemical production was soon eclipsed by geothermal power generation. The minerals found around the area (33 in total) include six rare borates,...
Ever had a discussion along the lines of "I have this old specimen, but it has no labels so I am not sure of where or what it is?"
Most of us have and the mystery sometimes never gets solved, we have quite a pile here, which sometimes has a happy ending...
To start 2016 off we have introduced a translation feature for e-Rocks.
This should be easy to use and hopefully cater for most users who's first language isn't English.
The translator applies to all pages, and when operational has a "Show Original"...
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 many will already know we maintain a daily blog of new listings, auctions closing and photography over on the e-Rocks Facebook page.
Over the last 18 months we have built quite a following and it is thanks to our Sellers, and Visitors that we've...
If you’ve tried to hunt for minerals using a metal detector, you are familiar with the challenges. Especially if you are looking for, say, silver at an abandoned mine where all of the structures have been leveled to the ground. Trash is everywhere. Old...

We have fixed the problem with accessing e-Rocks yesterday.
The rescheduled end times for yesterday's auctions are now updated.

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!

Within Peter Uerpmann's collection of European minerals we came across quite a large comparatively heavy specimen (110g) of slaggy matrix filled with bright metallic octahedrons of silver to 1mm stacked in pagoda-like parallel groups, labelled from ...
Something we do not see very often (maybe twice a year), the administrator's "auction items closing panel" for the next 24 hours is blank!
This means we don't have any auctions closing on Christmas Day, but we will be back on Boxing Day with a full...
A few months ago I came across the mineral aldridegeite in the IMA list of minerals whilst doing some research. This sulphate mineral is a member of the develline group first discovered and only found at Broken Hill, New South Wales,...
Today we saw our e-Rocks User registration count reach 7500; this means that barring the odd D.Duck and K.Kong we are connected to 7500 mineral collectors worldwide.
Great news if you are prospective seller, re-assuring if you have not already signed...
Frequently pointed out by kind visitors are the typos in the texts I produce - as always my thanks for the assistance with this!
This time this is not a typo of fluorite but an interesting specimen of a mineral variety I had not looked into before.
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...
It is Munich time again and I am sure you will have noticed a number of "Munich" themed auctions here on e-Rocks.
