New German Specimens

A run-down of some new specimens recently uploaded to the gallery.


Rötelsteinpfad am Güdesweiler Thunderegg – an unusually large specimen for a location that is very often incomplete and damaged. 


Kniebreche – a super-rare location, unfortunately given how beautiful they can be. 


Another Kniebreche specimen.

New Location: Ravensberg Mountain

Located near Bad Sachsa, Niedersachsen (Lower Saxony) – a state that provides very few thundereggs compared to some of the others. These are a distinctive location, with beautiful flowbanding and thin bands of sometimes vivid red agate. I have now added a page of them on the gallery, and here are some of the best ones.

Update to the Wonderful Querbitzsch Thundereggs

Some more specimens from what is becoming a personal favourite location – and unquestionably one of the most unusual locations in the world.  Querbitzsch!  The colours and patterns and structures possible here are just phenomenal. Here are some more specimens.

Two Californian Tilt Eggs

Tilt thundereggs, where the horizontal bands in some agate are oriented in different directions due to the stone moving in the ground, are one of the most interesting features you can fine.  Here are two specimens showing various degrees of tilt.

Turkeytail 03

TurkeyTail Bed thunderegg. In this stone, the tilt has ‘crept’ – slowly moving and laying down bands of agate in a fan structure.


Unknown location – Possibly Middle Hauser or Potato Patch West. This one shows some dramatic events that have shattered the agate and left it to ‘freeze’ again inside a new material laid down at about 30 degrees to the original. Other half below.


Some New Köpfchen Thundereggs

Some more specimens from one of my favourite locations, showing off the warm colours and interesting structures that you can find here.


The last specimen is especially interesting since it has a healed/filled crack at the bottom right, which seems to have led to an inflow of debris that has become bound up in the waterlines.  Click here to visit the full gallery of these stones.



Eddy Bed Update

A few new specimens on the Eddy Bed gallery.


An interesting specimen with tilt lines. The main tilt takes place towards the top, but there is also some very very slight tilt going on lower down, which is only really visible if you place a horizontal line against the image. Note that the crack in this one seems to end precisely on the point where the main tilt starts – though there do seem to be some faint marks in the agate above it, which I am not really sure about. Angling the stone against the light reveals that the visible flaw in the surface stops precisely on the boundary between the main waterlines and the white sliver that starts the tilted lines. Does this suggest that whatever geological event tilted the egg in the ground also caused that crack? See the detail shot below.

A larger specimen of 11.5cm


A specimen substantially filled by an intruding rubble pile.

The Green and the Grey (And the Light Brown)

Two classic Crook County locations have received an update on the gallery – Killer Green and Fallen Tree.  Both are powerful examples of understatement – fairly quiet, usually without any fantastically elaborate agate going on, but also extremely beautiful.  Below are a few of the new specimens, starting with Killer Green.


Sometimes the simple just wows. This is a very simple specimen with gentle grey agate surrounded by green – but what a beauty!


Colours other than the basic green and grey are quite rare here. This one has a layer of dusky purple opal, which also makes this quite unusual.


Another one with unusual features – a very complex core with green tubes, complex white textures and an opal floor visible through clear quartz.


An unusually dark specimen with hints of red-brown around beautiful grey agate.

And some Fallen Trees:


A specimen with quartz (with negative crystal casts) floating in clear agate.


A complex moss specimen.  The crack leads to a negative crystal cast


A zeolite specimen.  I am told that the zeolite specimens from Fallen Tree are rather looked down upon in some quarters, and they are often discarded and left unpolished. I suppose if you get the same thing over and over then maybe, but this one at least seems a beauty to me! The zeolite is probably clinoptiloite.


And lastly a delicate green-tinged specimen

The White Ghosts of the Kaolin Mines (Again)

Querbitzsch Thunderegg

I am totally besotted with Querbitzsch thundereggs.  I really think that when they are at their best, they are among the most beautiful in the world – and much of the time they don’t have anything that can be called ‘agate’ at all. They are just magical! White ghosts of the Kaolin pits …

There will be more of these.


Sokolwiecz Again


It’s not so long since I last updated these, but I had to share this specimen.  The location, always a tricky one to find in any quality, is really highlighted by this beautiful thunderegg.  Click here to see the other specimens on the gallery.

Schmiedeberg by Dippoldeswalde – An Obscure but Colourful Saxony Location

A rare and obscure Saxony location that is distinctly different to most others that I have seen from the region. These may seem insignificant compared to the mighty agate specimens from other locations, but these are actually the kind of interesting and subtly beautiful specimens that I really love. They come from a solitary source of porphyry in southern Saxony.

They have cores of silicified mud, rough chalcedony, quartz or just interesting swirls and stains. Surprisingly colourful and I look forward to examining some more of these.


They are sometimes known as Altenberg eggs, but that name is rather less specific.  I had an Altenberg thunderegg on the gallery for some time, but now I am happy to publish a page containing several more Schmiedeberg by Dippoldeswalde specimens.


More of these are on the way, and I look forward to seeing what else the location has to offer.
