Summary

[edit]
Description
English: Quartz (Var.: Amethyst), Calcite
Locality: La Sirena Mine, Guanajuato, Municipio de Guanajuato, Guanajuato, Mexico (Locality at mindat.org)
Size: 9.3 x 6.1 x 4.8 cm.
This fine amethyst specimen from the La Sirena Mine at Guanajuato, Mexico is distinctively different, than most you see from any other locality. There are actually three generations of quartz on this piece, which is nicely accented with two small clusters of milky calcite rhombs. The pretty purple amethyst crystals are sheathed in lustrous, frosted quartz on the sides of the crysals. The sharp, amethyst terminations are composed of water-clear, colorless quartz. Looking down onto the crystals gives a surreal phantom-like look, with the amethyst inside of the frosted quartz sides. Uncommonly fine material from this famous locale. Ex. Consie Prince Collection.
