Dumbrava Update

Just for old time’s sake, here’s my old and beloved Dumbrava thunderegg again:


I always thought this was a superb location, with is beautiful blend of clear agate pools and bright colours.  Now I am very happy to add two more to the set.

Breaking News – New Oregon Thunderegg Location Discovered near Wild Iris


Specimen with almost-plume

Here are a few specimens – among the first ever cut – from the as yet un-named bed Jason Hinkle has recently discovered close to his Wild Iris location. Of the 20 I cut, these are the most exciting – one almost containing plume, one waterlines and one shadowing. The vast majority contained thin cores of featureless grey agate. So far they may not be winning any awards, but at the same time, there is definitely things going on in these eggs so very much worth keeping an eye on them!

An example of a typical specimen from here - a deep pool of simple grey.

These are not yet on the gallery.  I will be publishing them as soon as I can get a name for the location out of Jason!

Introducing the New Wild Iris Thundereggs – one of the finest plume thundereggs in the world


The Wild Iris thundereggs are a new discovery by Jason Hinkle about 15km from Richardson Ranch – and the similarity is very clear. At first glance, there is an obvious kinship with the Richardsons – indeed, one might even call them a ‘drabber cousin’ or ‘just another of those satellite beds’ . . . until, that is, one gets to know them. As the eggs began to emerge from the bed and more and more were cut, characteristics that make this a very individual and distinct bed began to emerge. For one thing, these stones contain some of the highest frequency of plume of any thunderegg I have ever seen. Out of the small sackful I cut myself, I ended up with a whole handful, some among the best plume thundereggs on this gallery. Also, while the commonest colour by far is a very simple clear grey agate, when colour appears it is also distinct – often a very soft and beautiful pastel yellow or, most precious of all, a soft pink-red. Yellow and deep yellow-brown also tends to be felt in the moss and plume here, as well as invading the matrix – you might call it the main defining pallet of the stones. Another feature that often appears is a white opally material often characteristically chopped up, fragmented and scattered as bizarre inclusions – a type that is seen in Richardsons but here goes even further. I have no idea at all how this formed.


What makes these thundereggs truly magical though is their clarity. The agate is very clear, often allowing you to see right down into the depths and in this case definitely meriting the term ‘rock pool’. In conjunction with plume and other inclusions, this can create worlds of beauty that place these among the top stones in the world, in my opinion, for all their quietness and seeming simplicity. Unfortunately this means that it is just about impossible to take a still image that ever does them justice. I can state categorically that NONE of the following images truly do them justice, or even come close to showing the deep and mysterious worlds that these possess. More so than any other thunderegg I know, they have to be seen and handled in the flesh. So you will have to use your imaginations and maybe see if you can track down some of your own. It is very much worth it!

One last point to make is that the first material to be dug here, and at the moment that’s all of it (!), comes from near the surface, which gives the already brittle matrix from this area even more fragility. It remains to be seen what the bed will reveal deeper down. I personally am obsessed with these stones, and I will be watching with great interest to see what the future holds.


In conclusion, this is an extraordinary location – one of the most beautiful new finds to have come along recently.  It has very quickly become one of my personal favorites and i have plenty more awaiting either cutting or polishing.

Shelves for the Gottlobs


So after all this time, I finally manage to get some proper shelves put up for my most precious individual thunderegg locations.  Just cheap shelving but what can you do?  These are my shelves of the rare Gottlob thundereggs from Germany, which as anyone who knows me will know, I have been chasing and obsessing over very hard for years!  And if there’s one thing harder than photographing a Gottlob thunderegg it’s photographing two shelves of the things!

I somehow never realized just what a larger collection of these I had managed to gather until I finally managed to get them all in one place!  It feels good!  Still need to sort things out though – could really use some light on them and some proper risers and stands etc.

I just wonder how long things will remain this tidy though . . .

Hopefully some new locations will be going onto the gallery soon as well.  I have plenty lined up here waiting to be published!

Green Updates – Killer Green, Donnybrook


I have been updating the gallery recently after a period of quiet.  The gallery of Killer Green thundereggs, one of the world’s finest green thundereggs, has been rejigged with several new specimens, including some spectacular amethyst ones, like the above.  Also a beautiful new specimen with rough mineral streamers:


I also took a re-scan of one of my favorite stones of all time.  I have had this one for years but now hopefully managed to capture the colours a bit better.  The amethyst here is little more than a smudge, but it forms a very striking and colourful whole.



See the full gallery here.

Donnybrook thundereggs have also seen a small update, mostly with rather more quirky specimens, such as this one that seems to contain a very odd little creature:

Donnybrook 09

I presume this is a slightly pillowy agate formation that threw out a white band (as common here) that just happened to connect and close off in precisely the right place.  Still it forms a bizarre little structure that is unique in my experience.  I also have the following small ‘fuzzy’ specimen with a texture that looks almost like toweling.  Also not so unusual here but a very quirky stone.  These are among the last of the Donnybrooks from the batch I cut a while back.

More updates soon I hope, including some unusual new locations!




New US State: Wyoming – New Super-Rare Location: Virgin Valley

thunderegg786Nothing like launching a whole new US state!  Here we have the first thunderegg I have ever even heard of from Wyoming – the so-called Virgin Valley.  It is a curious stone.  It might not excite agate lovers (all it has is very fine sparkly druze), but it is so drastically different from anything else I have seen from the US that it sure gets me excited.  It is a light-weight stone, both because it’s hollow and because the matrix is filled with air pockets in a manner more reminiscent of certain Saxony stones (Bokelwitz) than any other US location that I know of.

Incidentally, I created this image by photoshopping together a scan of the surface and a macro photograph deep into the geode, in an attempt to get a decent depth of focus.  It is next to impossible to get the entire stone in focus with the equipment I have, so this is an attempt to get around that.


Introducing Killer Green’s Dark Twin

Killer Green is one of the best known of the Oregon locations and one of the best known of the world’s green thundereggs.  It is justly famous and well-loved for its amiable blend of light green and grey and crystal etc.  But very recently (2012) it has been discovered that Killer Green has a dark twin.  These come from a secret location not so far from Killer Green itself (in the Harvey Gap region), and are known only as NJ1.  This new thunderegg is very similar to KG in some ways but has a depth and richness that is totally new.  Here, the greens are darker, the patterns deeper and more complicated – it’s a powerful mix and promises to be a major new discovery.



I managed to get a sack of rough specimens and have recently been cutting them.  The quality rate is a little on the low side, but still well worth it and producing exciting results.  Here are some examples and in time more will be polished  and loaded onto the gallery.  The stones are actually quite varied – more so than KG – ranging from deep green to greens so dark they are almost black, then sometimes moving into shades of brown and unexpected patterning.


There’s a few more currently on the gallery as well, and look out for more as I work  through my stock.  http://www.thundereggs.co.uk/usa/oregon/nj1.html
