Smithsonite from Broken Hill Mine, Kabwe, Zambia [db_pics/pics/ab108b.jpg]

Smithsonite from Broken Hill Mine, Kabwe, Zambia [db_pics/pics/ab108c.jpg]

Two large, double-terminated Smithsonite crystals that display dramatically on matrix. This locality is not known for volumes of specimens but I have seen the occasional really interesting specimen from here over the years and this counts as one of them. The largest Smithsonite is 3.6cm wide and the specimen displays well from either side. There are unfortunately small cleaves on the tip of each crystal, but they don't ditract that much, especially when considering the rarity of the piece and the overall visual impact.

AB113 - Tanzanite $ 3000

Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/ab113b.jpg]

Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/ab113c.jpg]

Stunning bi-color Tanzanite crystal of yellow over vivid purple/blue. This crystal has superb luster and unusually uniform shape, retaining an even 7mm thickness all the way from the base to the termination. There are two chips, including one on the back termination, but the sheer pizzaz and dramatic coloration greatly overcomes it, it's that pretty and unique. The best bi-color Tanzanite I've ever had. Weighs 13 grams.

Old Chinese Fluorite specimen from about 20-30 years ago or more when Chinese minerals were first coming out and unfortunately no specific mine name was available.

Brucite from Killa Saifullah, Balochistan, Pakistan [db_pics/pics/K941c.jpg]

Large, thick somewhat pinwheel formation of translucent yellow Brucite on a bit of matrix from recent finds in Pakistan. Undamaged and good from both sides, this is a very thick formation. The Brucite is well crystallized all around, characteristic of open pocket growth and not growth in tight, contacted seams as are most. An excellent example that is just plain more massive than most.
