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.
Coming up on 18th May 2016 is a huge auction of antique books at the German Auction house Reis & Sohn, Königstein, Germany.

In the world of minerals different localities can often be distinguished by variations in morphology and or associations; for example it is comparatively easy to determine that a dioptase specimen was collected in Tsumeb over say Kaokoveld or Altyn.
For those of you who check out my personal timeline on Facebook you will already be aware that I keep this fed with a steady stream of mineral photographs and sometimes (not so) witty captions!
I just do this for a bit of entertainment and interaction as...
Story covered by BBC local news for Derbyshire.
I am not sure if this is the same "discovery" made a few years back or something new.

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...
I am sure regular visitors to e-Rocks will remember a few "charity" auctions posted by Roger Lang, Montanpark we ran some months back.
These auctions were run by Roger to raise funds for LED display lighting for his local Mineral Museum at Imsbach,...

Here we are enjoying a fairly non mineralogical week away in Harlech, Wales.
This seagull apparently comes with the rental, certainly knows when the meal times are, and if not on time will tap at the window.
As seagulls go, he is very placid.
We all have them, but in the mineral world the continual exchange of specimens between collections, dealers and other collectors means that provenance and history can play an important part in the interest in a particular specimen.
When we were recently...
Back in 1979 at a place called Tomahawk Creek near to Rubyvale in Central Queensland, Australia, a 2020 carat (404gr) yellow gem sapphire was discovered.
