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.

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.
