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.

eddybed14

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 specimen substantially filled by an intruding rubble pile.

The Green and the Grey (And the Light Brown)

Two classic Crook County locations have received an update on the gallery – Killer Green and Fallen Tree.  Both are powerful examples of understatement – fairly quiet, usually without any fantastically elaborate agate going on, but also extremely beautiful.  Below are a few of the new specimens, starting with Killer Green.

Sometimes the simple just wows. This is a very simple specimen with gentle grey agate surrounded by green – but what a beauty!

Killergreen03

Colours other than the basic green and grey are quite rare here. This one has a layer of dusky purple opal, which also makes this quite unusual.

killergreen16a

Another one with unusual features – a very complex core with green tubes, complex white textures and an opal floor visible through clear quartz.

killergreen18

An unusually dark specimen with hints of red-brown around beautiful grey agate.

And some Fallen Trees:

fallentree19

A specimen with quartz (with negative crystal casts) floating in clear agate.

fallentree21b

A complex moss specimen.  The crack leads to a negative crystal cast

fallentree22

A zeolite specimen.  I am told that the zeolite specimens from Fallen Tree are rather looked down upon in some quarters, and they are often discarded and left unpolished. I suppose if you get the same thing over and over then maybe, but this one at least seems a beauty to me! The zeolite is probably clinoptiloite.

And lastly a delicate green-tinged specimen

The White Ghosts of the Kaolin Mines (Again)

Querbitzsch Thunderegg

I am totally besotted with Querbitzsch thundereggs.  I really think that when they are at their best, they are among the most beautiful in the world – and much of the time they don’t have anything that can be called ‘agate’ at all. They are just magical! White ghosts of the Kaolin pits …

There will be more of these.

Sokolwiecz Again

It’s not so long since I last updated these, but I had to share this specimen.  The location, always a tricky one to find in any quality, is really highlighted by this beautiful thunderegg.  Click here to see the other specimens on the gallery.

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.

Schmiedeberg_Dippoldeswalde02

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.

Schmiedeberg_Dippoldeswalde05

More of these are on the way, and I look forward to seeing what else the location has to offer.

Sailauf Update

Again, mea culpa … some more stones that have been hanging around for far too long, this time from the two Sailauf locations in Germany.

rehberg03

This is a Hartkoppe specimen that really brings the location to life – very intricate and beautiful.   5.3cm

rehberg02

The above is a rather different specimen from Rehberg – much larger (12.5cm)  and with a curiously neat core of simple solid agate.  I like it for it’s shape.

And finally one more small Hartkoppe specimen, showing fiery red agate.
