Mineral Spot: Cassiterite...
Cassiterite is a tin oxide and has been mined for the production of tin metal for a couple of thousands of years. Good crystals are found in a number of tin mining districts around the world, and those from Rossarden in north east Tasmania are amongst the best.This specimen is one of a number of specimens that will be in this weekend's upcoming auction.

Mineral Spot: Descloizite...
Descloizite is an uncommon lead vanadium mineral found in the oxidised zone of mineral deposits. This particular specimen has an interesting story to go with it. It was given to me by a Broken Hill mineral collector as an unknown mineral, supposedly collected underground in the Zinc Corp Mine, Broken Hill by a miner. It is clearly from Berg Aukas in Namibia, not Broken Hill. The specimen is about 30mm tall.This specimen is one of a number of specimens that will be in this weekend's upcoming auction.

Mineral Spot: Pseudomalachite...
An uncommon green or blue-green phosphate mineral, pseudomalachite is so-named for its similarity to malachite. I rarely forms as distinct crystals, more likely as rounded aggregates.This one is from Lake Boga in Victoria and a good example. I have been going through a lot of Lake Boga material recently and photographing a number of specimens. Many of these can be seen here.

Mineral Spot: Native Copper...
Well, I am finally getting back to normal. Following closely on my back operation, I had to have an emergency operation to remove my gallbladder. I didn't even know that I had gallstones until three days before the operation! Still, recovering well, and due back at work next Monday.This specimen, although looking like something someone has dropped into a sugar bowl, is in fact, a specimen of native copper from Virneberg near Rheinbreitbach in Germany, and is one of a number of specimens that will be in this weekend's upcoming auction.

Its the middle of Winter and the sun is still shining brightly (or it was a couple of days ago when I took this photo. Today's seen snow flurries!). This Tasmanian Rosella, also known as a Green Rosella (Platycercus caledonicus) was feeding on seeds from a silver birch just outside our kitchen window...

Mineral Spot: Wulfenite...
It has been a while since my last entry, over two months in fact. I have been sidelined due to back problems and had a back operation about three weeks ago. Recovering though...This is a specimen from the Ojuela Mine, Mapimi, Durango, Mexico and has three mineral species on it, two of which can be seen in the photo. The yellow square-looking crystals are wulfenite and the paler spiky crystals are mimetite. The third mineral present is smithsonite. You can just see some white crystals in the background.
This specimen is one of a number of specimens that will be in this week's auction, also the first for quite some time. Hopefully, things will be fully back to normal soon!
