Well, things here have been a bit crazy lately, mostly due to publishing and writing matters. But here’s one new location to keep you going – one that I will be loading onto the main gallery as soon as I have a moment.
Brendas are one of the more obscure ‘named geodes’. You wont find that much info about them on the internet but they are recognised among the geode-cracking brigade. However, when a bunch of them began to appear on ebay, it quickly became apparent that they are actually a type of thunderegg. As is often the case with geodes, most were cracked open but there were a few cut specimens and one quickly made its way over to me. It was recently polished, and here it is. A rather curious thunderegg all round really, with a bizarre mix of materials and spaces where materials have weathered away in the core. Many Brendas just have crystal cores, but when agate does appear it is a rather rough, opaque red and white, as here. The black material is a bit of a mystery to me. It’s extremely soft and could be a kind of decaying calcite, but I wouldn’t like to say for sure.
A second, larger and possibly more dramatic specimen is also on its way. With tilt lines! So watch this space.
