Summary

[edit]
Description
English: Quartz
Locality: Paprok, Nuristan Province (Nurestan; Nooristan), Afghanistan (Locality at mindat.org)
Size: cabinet, 10 x 8.5 x 8 cm
Tourmaline with Cleavelandite on Quartz
Purple-capped tourmalines are quite rare, and this piece has a distinct purple zone, above a blue zone, on its termination. More than that, it is just a very fine and aesthetic tourmaline specimen by any standard, with the color as a bonus feature. It is, first off, not repaired. Most large matrix tourmalines from this region are repaired at least once, especially when connected to a quartz crystal as this is. And, the quartz and cleavelandite are arranged in great balance, not overwhelming but accenting the tourmaline itself. The tourmaline is very equant and robust, about 7 x 7 x 7 cm overall in size. It has an extremely unusual and glassy termination...intricately scalloped, for lack of a better word. It has many subtle growth features that result in incredible reflections and sparkle coming off that termination. I cannot say that I have ever seen this style of termination on such a large crystal - just on small ones, before. Lastly, the piece is shockingly pristine. It weighs 782 grams. The purple color, especially in a lustrous termination, is perhaps the rarest of all colors on a tourmaline. In particular, it’s very rare from this part of the world where they tend towards pastel hues of pink and greens.
