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.

The Glorious Vivid Colours of Felsenschlag – New Specimens

Felsenschlag 44Felsenschlag is one location I just cannot resist.  These days I am fussy, but still, every so often I am lucky enough to add a few more to … well, it was a dedicated shelf once, now it’s more like a ‘pile’.  The warm and vivid colours of the agate here can be world-class – unquestionably one of the greatest thundereggs of any continent.

Felsenschlag 41 I have just uploaded a major update to the gallery of these stones – sixteen specimens.  And here on the blog is a chance to wallow in the best of them.  Enjoy!

Gravel Pit Fun


Pomßen Gravel Pit Thunderegg

Several new specimens from the various German gravel pits have been uploaded to the gallery now, including the first specimens from the Pomßen and Baden Baden pits.


Baden Baden Gravel Pit Thunderegg

Rather than being locations in their own right, the gravel pits in germany are areas that were dumping grounds for thundereggs carried in from elsewhere by river systems. The result is a hodgepodge of different rocks, sometimes with an identifiable source, sometimes not. Exactly how to process these stones is always going to be a bit problematic – sometimes you can say with some certainty where a rock may have originated, sometimes not – and they are usually tagged depending on the location of discovery rather than origin. As a result, the images presented here will be almost useless for ID purposes since stones of the same type can turn up in many pits and many types can turn up in one pit.

One thing that does set them apart though is their water-worn exterior.  Many from the gravel pits are incomplete, broken or worn down and for me, who has rather a thing about completeness, that is a bit of a problem!  That also means that my gallery might be a bit less than totally representative of what you usually get out of the pits.  But whole eggs do turn up, and these ones here are the ones I have managed to trace recently.  There’s a few more awaiting polishing as well, which will have to wait for a future update!

One thing to add is that I am currently awaiting the arrival of a specimen from the Erfurt Gravel Pit, which is essentially a water-worn Seebachsfelsen.  It will be interesting to see how this compares with the locations from other parts of Germany.  Will have to post that later though!

Finally, I know I have shared this before, but here’s another look at my favorite of all the gravel pit eggs, this complex white beauty from Otterwisch!

Revisiting Lierbachtal

I have finally managed to do a decent update of the German Lierbachtal thundereggs, which not only includes some nice new stones, but also some named sub-locations, which are very rarely encountered.  There are many beds in the Lierbachtal area, but it is rare indeed for stones to be labeled anything other than ‘Lierbachtal’.  The gallery now hosts a small selection of named stones, alongside a very large gallery of general ‘Lierbachtal’ specimens.

A word or warning though: use these named specimens with caution when trying to ID stones.  There is a lot of variation here within the beds.

Click here to visit the Germany gallery and see the new named locations, or continue reading for some named and unnamed highlights.


Extraordinary specimen with loads of features. Onion ring formations dominate the centre, but a precise layer of the lierbachtal sea green agate has formed among them. And above that, like the sky over the sea, is an inferno of orange and peach sagenite agate. An amazing stone.


Here’s a little Lierbachtal thunderegg that has got me puzzling. It was part of a cheapish bundle deal (with a handful of other rocks that went straight into my shop pile!) and the only reason I bought it. When I bought it, the term amethyst was bandied around, but now I actually see it – well, I never really saw anything like it before! The purple smudging gives way to distinct purple needles within the cloudy white crystal in the centre.


A massive and colourful specimen, unusually with waterlines.


A classic pseudomorph specimen, filled with geometric patterns.


A named thunderegg from Niedermättle showing an interesting smeared and crumbled matrix in the centre. This is not uncommon in Lierbachtals, but in thundereggs as a whole is very bizarre.


This one is a real oddity. It’s from an extremely rare sub-location that doesn’t even have a name (maybe it should?). Interesting healed cracks in this one – one blood red and one with white quartz.

Into the Heart of Darkness and the Devil’s Pulpit

Teufelskanzel11No question, Teufelskanzel Thundereggs (Devil’s Pulpit) are one of the most spectacular German stones out there – black stormy agate sometimes shot through with blood red.  They are like metaphorical stormclouds – hurricanes of the soul.  Or indeed, the swirling horror-book styles of the devil.  Stones you almost expect to see move like a time-lapse image of a cloud or the stormy surface of an alien planet.  It’s rare to find them in any quality though – but I have been hunting hard for these, and here are some new specimens that truly live up to the name Teufelskanzel!  The above one in one of my most precious thundereggs – a larger and unusually complete and finely formed specimen – the red eye of the storm without a doubt.

Teufelskanzel07This was the specimen that first got me to apply the nickname Heart of Darkness – because it truly is.  A chaos of black and grey – the symbolic evil that lurks at the heart of the human race, frozen in a stone that novels could be written about.

Teufelskanzel08A little light relief among the Devil’s Pulpits – and quickly nicknamed “The Drip” for it’s curious shape.  I tried for a while to sell this one unpolished, but no takers.  So i polished it and it’s MINE now.  A quirky strange little stone that i love.

Teufelskanzel10And lastly another example of colour in a Teufelskanzel – a deep rich brown, spiced with the classic blood red.  This is an example of just how fine the agate here can become on occasion.  A complex and beautiful pattern.

I have recently been lucky enough to secure a large new stock of these, currently on their way to me.  So there will be many more voyages into the heart of darkness in the future – and many more for sale . . .

Colourful Heuberg Thunderegg

Heuberg03A small update to the Heuberg page of the gallery included this rather lovely and very colourful specimen!
