A Curious Float Egg from Richardson Ranch

An obscure one here. The location known on my gallery as “Richardson Ranch, On the Road to the New Ledge Jasper Beds” is obscure enough – one of many unnamed beds in the area that are only really known at all thanks to Ed Pieters doing such a marvelous job of exploring the ranch. Except … this isn’t one of those. Oh, this specimen was found at the “on the road to …” location, but this is a float egg – an egg that has been knocking round loose on the surface and must have been transported from elsewhere. It is clearly different in geology, being much closer to Flat Bed. A wanderer thunderegg and, as far as I know, a one-off.

Hey, we egg-heads get excited about such things. 🙂


For comparison, here is a new specimen from the “On the Road to …” location itself that I have just uploaded.  It is one of the redder locations on the ranch, characterized by this crisp grey agate.richardson_road-newledge02.jpg

Just for the fun of it, here is a previous Richardson float egg – a favourite of mine because it is so different from anything else that I know from the ranch, and also because that matrix is just beautiful!Richardson_float01.jpg

Esterel La Vigne – One of the Greatest Thundereggs in the World

Esterel La Vigne Thundereggs is an extraordinary location of usually small but exquisitely structured and colored specimens.  It’s a location I really focus on, and every so often, I add another to the gallery.  Here are a few more of them:


Two Cores – Two Flames


A beautiful Blend of Green and Lilac


A Massive (For Here) and Flaming Double Specimen


An Unusually Large specimen for the Location at 9cm

You can see plenty more of these, as well as detail shots, on the gallery page here: http://www.thundereggs.co.uk/france/index_vigne.html

And finally a specimen from the much rarer cousin location Plateau de Grane:



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.
