RC99P8: Quartz (variety amethyst)
Probably this is one of the first amethyst samples from Las Vigas because the original label indicates that it was acquired in Tucson in 1968 and (erroneously) 'Guerrero' as the locality. It is a very aerial group of crystals, some of them doubly terminated, with a very well marked color zoning. Luster and transparency are excellent.

TF30L3: Quartz (variety amethyst) "phantom"
From a locality not yet well known by mineral collectors, the crystal presents a very curious flattened morphology, where two parallel prism faces have virtually disappeared.

MTX56CD1: Quartz (variety amethyst) after Fluorite
In Sidi Rahal, these Quartz crystal growths (amethyst variety) that replace the walls of cubic Fluorite crystals, have slightly amethyst color tones, which is why this specimen is so unusual. Its intense color, equivalent to that of the amethysts from Brazil, gives this specimen a very high level of quality. The Magazines ‘Lapis‘ and Le Règne Minéral‘ know this, and that is why they both reviewed it as a novelty for Munich 2023.

TD13J5: Quartz (variety amethyst) and Epidote
Magnificent crystal, very well defined and bright with an esthetic graded change of color clearer at the base and deeper on the termination with zoning.
