Summary

[edit]
Description
English: Quartz
Locality: Amatitlán, Municipio de Zumpango del Rio, Guerrero, Mexico (Locality at mindat.org)
Size: large cabinet, 18.3 x 6.5 x 4.7 cm
Amethyst
This is an outstanding, GLASSY AND GEMMY cluster of amethyst from this famous and very sparsely producing locale. It has the deepest purple, grape-juice colored amethyst cores you could want, grading to a clear zone at the very tips. The display face you can look right down into, as the glassy, transparent surfaces facing front let you look deep within. Having handled a number of these, including the famous Romero collection pieces, I can say that while not the biggest, this is among the best for quality you can ask for. It is nearly pristine, and in fact you have to look really close to find just one ding on the front at all (a tiny nick off the smaller sub-termination). Although larger amethyst crystals occur elsewhere, for my tastes the combination of the color and qualities in great Guerrero material make them the world's best of species. This is an excellent example of why I say that. It is from the Marc Weill collection, but would have been most likely mined in the 1970s or 1980s.
