Amethyst – Zacatecas, Mexico
 A highly lustrous, crystallized quartz specimen from Mexico, featuring a high luster on both sides. The sharp-edged crystals are crystal-clear at the tips and fade to a brownish-dark purple. White inclusions within the crystals add a special depth to the specimen. The reverse side of the quartz is completely recrystallized.
 Very beautiful historical collectible from Zacatecas.
