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.

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.

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.

Canada gets a New Location: Star Spirit

Keeping to the north-west of the American continent, we have a new location from Canada to publish, which is a very rare event.  Star Spirit Thundereggs are found in colourful indigo and orange clays on the island of Haida Gwaii, British Columbia (formally known as the Queen Charlotte Islands). They are relatively large and feature a very attractive colour scheme of greys – a deep grey-green matrix surrounding clear grey agate, often with bands or waterlines. The beauty is also in the bold shapes they tend to form.

On both these specimens, the polish was somewhat problematic and I really need to rework them a bit one day.  For now though, here are the specimens with a little bit of processing to minimise the issues, and hopefully that wont stand in the way of appreciating what a fine and powerful location this is.

The Langer Rain Mystery

Langer Rain thundereggs recently appeared on the scene from Germany, causing a little excitement as a possible new find – similar to the classic Felsenschlag, yet different.  I quickly bought three of them.  Unfortunatly, the realisation came soon enough that these were just stones from the so-called ‘New Hole’, which isnt so new now.  HOWEVER, Langer Rain is a much more poetic name, so I am happy to add it to the gallery anyway.  There’s a limit to the usefulness of names like New Hole, after all, and people should be more creative with these things!  The stones I managed to acquire are also a nice upgrade on my one previous ‘New Hole’ specimen.

It’s no easy matter to distinguish Langer Rain / New Hole from the classic Felsenschlags, but set them side by side and you can see that they do have a certain identity, being characterised by darker and less red agate – verging into chocolates and mahoganies.

Here they are:

New Location – Mt. Airy, Nevada

I wait for years to track down a specimen of this rather obscure Nevada location, and then three come along all at once, including one really nice larger specimen!  They show a great depth of blue grey agate.

Australian Updates – Couchy Creek, Yandina and Hummick

Three striking new Australian locations have been added to the gallery now – including some extraordinary beauties from Yandina (North Arm).  For me, these are easily one of the most beautiful Australian thundereggs of all – a truly stunning gentle and colourful aesthetic, often with inclusions.  Because they are so lovely, here are ALL THREE of them!

Next up is Couchy Creek.  This is a rare Australian location characterised by an extremely soft matrix, almost the consistency of chalk. The cores are usually pale grey-brown agate and crystal, sometimes with complex inclusions. For polishing, consolidation with glue/resin may be advisable. Below you can see a consolidated specimen (first) and an unconsolidated one showing visible wear. Please note though that the unconsolidated one has been ground into a smooth round shape!

And finally a real curiosity.  Hummick Creek is an unusual location that is usually a mudball or very close – but still highly distinctive and really beautiful. They have a pale subtle matrix usually in concentric circles, and often marked with flaws.

Look out for more Australian stones soon.  There’s still plenty to go!





First Australian Updates: Chillago etc.

It is time to embark on a major Australian update.  There is quite a string of new locations that have accumulated and this will be a massive improvement to the Australia page on my gallery.  I will be working through them a few at a time, beginning now with one of the most beautiful of all – Chillago.  Chillagoe01

Chillago is an extremely rare and little known Australia location with a matrix that is very distinct from the more familiar locations, and often showing a very pronounced red agate. The above specimen is an absolute stunner!

Next up, i have finally added a Mt Tamborine – not so unusual but still difficult to find in any quality and tending to be quite high-value.


There are plenty more new locations to come, but i have also updated some more familiar ones as well.  Here, for instance, is a classic Agate Creek – was there ever a type of thunderegg that was such a perfect representation of it’s country of origin as these? They just LOOK Australian – red earth, heat, desert, wild weird landscape …

This one is also a tilt egg – the lines in the core indicate that the ground moved at some point during formation. Seismic activity frozen in stone.


Lastly for now, a more unusual Agate Creek, identified as coming from the so-called ‘Campsite Bed’ – something a bit different to normal.


Keep an eye on the Australia page as more will be creeping on there soon – and i will present the best ones here, of course!




More German Locations

The endless parade of new German thunderegg locations still shows no sign of stopping – and they are every bit as confusing as ever with uncatalogued location clusters, things turning up in rivers, new discoveries and old ones …

Here’s a run-down  of new locations on the gallery, beginning with Saxony.



This is a Minkwitz egg.  The gallery has presented the vein agate form from this location for a while – here though is the other, nodule form.

And onwards into the heart of the t-egg storm – Thuringia:


All this time, I regarded Spießberg as a ‘location’ – but no, that would be too easy.  Apparently there are many locations around there, of which the classic white agate specimens are just one.  This is another – though who knows which bed it’s from!



Another from the Spießberg area – more specifically from the Rennsteig hiking trail.  A new find and one of the most beautiful new things to come out of Germany in a while.



This is a Körnberg thunderegg – from “a higher mountain behind Gottlob”.  Not to be confused with Kornberg and Komberg eggs of course …



An incomplete Lippers specimen with a very interesting plated core.


This is Manebach – a location that is very hard to get out without breaking them. 


And lastly, this is a Kniebreche thunderegg, which also solves an old unknown mystery that’s been on the gallery for a while …

So there you have it.  The Germany page is getting so large i might have to split it up at this rate – and also should find some more sensible way to organise it all.  But that’s for the future.  In the meantime, I have no doubt the locations will keep coming!
