OLD-SCHOOL GUERRERO AMETHYST — WITH KILLER PROVENANCE

OLD-SCHOOL GUERRERO AMETHYST — WITH KILLER PROVENANCE.

Now THIS is a special one.

An incredible Quartz var. Amethyst from the Valenciana Mine, Amatitlán, Eduardo Neri, Guerrero, Mexico — a classic locality famous for producing intensely colored, glassy Amethyst with dramatic purple zoning.

The crystal architecture on this piece is next level — a sculptural grouping of elongated, sharply terminated crystals with that unmistakable deep grape-purple color concentrated through the interior, transitioning into lighter, almost colorless zones toward the terminations. Similar zoning is characteristic of fine Valenciana Mine material.

But the provenance makes this one even better.

Label notes: “Rec’d in trade from Joe Dorris (Glacier Peak) @ Mar. 1993 ABQ M.C. Show”
Later Weinrich Minerals, Inc. label — specimen no. 2062510

So you’re not just looking at a beautiful Guerrero Amethyst — you’re looking at a piece with 30+ years of documented collecting history attached to it.
