Rare Agareless Giant from Gold Basin, California

goldbasin04Not a new location, but this 23cm monster has been hanging around for a while awaiting polishing – and here it is.  This is an unusual Californian location that i have yet to see any agate in.  Instead the cores are complex blends of crystal and minerals of various kinds.  I also took some detail shots as the stone is so big and busy.  You can see the other smaller Gold Basin thundereggs here.

Intermezzo: Let’s Hear it for Tiny Thundereggs

DSCN2173Let’s hear it for tiny thundereggs! They deserve more attention.  Size: 1.7cm  Oh and it’s a Teufelskanzel / Devil’s Pulpit.


Hinkle’s Red Walnuts are Apparantly Called Hinkle’s Red Walnuts

Half of the almost-plume specimen

I should apologise – it may be partly my fault! This is what I christened them while waiting for the discoverer, Jason Hinkle, to come up with something more permanent. And yet, somehow – here it is! The name was accepted and is now recorded and registered for posterity.

I introduced this bizarre little deposit of simple but distinctive eggs a while ago but now they are on the gallery under their name.  I still havent polished any more out of the small batch that I cut, but as I said, these are the best of the bunch.


Hinkle’s Walnuts Uncut

Enigmatic New Tri-State Thunderegg.

Tri-State Thunderegg

Tri-State Thunderegg

This stone is an enigma. It surfaced as a new discovery in 2014 surrounded by an inordinate amount of secrecy. All I know is that it is from the Tri-State area where Oregon, Nevada and California come together. So far, very few have ever been released and it is unclear what will happen next – and indeed if or when there will be more or if it will ever be named. I hope so because the colours and flowbanding promise a very striking location indeed.

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 . . .

A few New Nowy Kościółs

nowykosciol21There is no question that Nowy Kościół thundereggs are one of the great locations globally, but it’s been a while since i put any more online.  Here are a couple more though, including the extremely vivid specimen above that i call the Harlequin Stone.
