I'm a Norwegian systematic collector, with focus on micromounts. My collection is worldwide systematics, but I also have several locality collections.
I'm living close to the larvikite complex, in Skien, Telemark to be more precise, and am collecting in the larvikite quarries as often as I can. There is almost always something to be found, and you can check out what was found on latest trip, reading my blog. Beside being out in field collecting, or checking the rocks under the scope, and mounting what I like, I also like to swap. You find my trade list as an article here. Do you find anything of interest, don't hesitate to contact me telling what you might have to trade.

Daoping Mine, Gongcheng Co., Guilin Prefecture, Guangxi Zhuang Autonomous Region, China

Dimensions: 2.3 cm x 1.1 cm x 1 cm

2.3 x 1.1 x 1.0 cm

The finest contemporary green Pyromorphites available right now are those from the Daoping mine in China. I was told that the section of the mine that produced these pieces is possibly closed and might not again produce these superb Pyromorphites. This specimen is a beautiful example consisting of sharp, green, hoppered, slender hexagonal crystals. A nice thumbnail size piece from this contemporary classic locality.

Little Patsy Mobile

Little Patsy pegmatite, South Platte Pegmatite District, Jefferson Co., Colorado, USA

All roads to these quarries are closed to motor vehicles. Except for the one person who owns a house further up the road. Mineral collecting is not a good enough excuse for the county to give you the combination to the lock. the distance to the mine is 4.5 miles one way. So I set up this rig. a ladder comes in very handy at this pegmatite. Although it was hard work on such a hot day. 100 degrees farenheit! Photo; Rudy Bolona; August 2, 2008.
