S9501390) Spessartine - Nani, Loliondo, Arusha Region, Tanzania
Size: 7.0 x 4.2 x 4.1 cm (small cabinet)
Price: $ 3800 (=~ £ 2445)
Several years ago neat loose spessartine crystals, some quite large, appeared on the mineral market. In my opinion these commanded very high prices considering the fact that they were not on matrix and were for the most part opaque. Recently good matrix specimens have appeared. This is one of them. A superb sharply formed, for this locality, orange opaque lustrous spessartine crystal measuring 4.0 x 2.5 x 2.3 cm in size is set aesthetically upon a 7.0 x 4.2 x 4.1 cm schist matrix. No damage and quite aesthetic. An oustanding matrix example for this new and important locality for the species.

An absolutely superb 6.4 x 2.4 x 2.2 cm single terminated crystal, gemmy throughout, of tanzanite. Complete all around. Some light chipping is present on some edges as seen in the photos. The luster is outstanding - the crystal faces are like glass. The crystal exhibits very well the trichroism that makes this gemstone so popular and famous. The first two views show the crystal with back lighting, thus exhibiting the color change. If lit from the bottom, the interior of the crystal is red. The quality is simply outstanding.

A neat and unusual combination specimen for tanzanite! A partly gemmy blue to bluish-purple terminated tanzanite crystal measuring 3.2 x 1.8 x 0.7 cm in size is perched on the side of a crystallized white calcite matrix. Attached to the side, and coming off the back of the tanzanite crystal is a pale bluish-gray grouping of terminated prehnite crystals measuring 2.5 cm in size. No damage - this shows all around 360 degrees. Good tanzanite specimens in combination with other minerals such as this piece are not common. Ex Lloyd Tate collection.
