Attractive mostly gemmy deep reddish-brown lustrous sharply terminated crystal of topaz 2.5 cm in height coming off of a rhyolite matrix. Several smaller topaz crystals are present. This is in very good condition.Mina Veronica, located near El Copetillo in the Villa Garcia municipality of Zacatecas, Mexico, is internationally renowned among mineral collectors for producing exceptionally sharp, vibrant red and sherry-colored topaz crystals. Geologically, these prized gemstone specimens crystallize within gas cavities or vugs inside high-temperature, fluorine-rich volcanic host rocks such as rhyolite or associated hydrothermal veins. Mining activity at this locality is small-scale and artisanal, driven primarily by dedicated mineral prospectors and collectors who carefully extract the brilliant, glassy prismatic crystals from surrounding volcanic matrices rather than through large-scale industrial operations.
