Spessartine from Nani, Loliondo, Tanzania [db_pics/pics/K527b.jpg]

Spessartine from Nani, Loliondo, Tanzania [db_pics/pics/K527c.jpg]

Complete 'citrus' orange Spessartine crystal from old finds in Tanzania. These were mostly found as partial or damaged crystals with perfect complete crystals such as this much less common. Equant form with very minimal edge wear, otherwise no damage. There are a few small areas of black Braunite inclusions, otherwise it's nothing but gemmy orange. These were often cut up into spectacular gemstones, and this one could cut a number of small gems.

Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936d.jpg]

Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936e.jpg]

Rare polyhedral Agate from Brazil, famous for the their angular geometric shapes rather than the more typical agate form of rounded nodules. How these formed is still debated but the general consensus is that they are the result of agate forming in the space between preexisting crystals of other minerals such as gypsum, barite, or anhydrite. These were found in the 1970s and the locality that used to produce them is now under water due to the construction of a dam. This is a good large example in excellent condition.

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
Merelani Hills, Arusha, Tanzania

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.
