Parallel growth of amethyst crystals, with a second generation of small Quartz crystals, some of them doubly terminated, which grew perpendicular to the specimen main axis. Color is more intense in terminations. A very curious specimen for the locality. This specimen is from the AVE (Spanish High Speed Train) quarry works where actually it is quite impossible to obtain quality specimens.

Specimen size: 6 × 3 cm = 2.36” × 1.18”

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. We would like to call your attention on the extraordinary transparency and the attractive distribution of intense violet cloudy forms inside the specimen.

EC12N9: Quartz (variety amethyst) 'hour glass'

A novelty at Ste. Marie 2009. Doubly terminated crystal with very well defined color zoning, reminding one of an hour glass, and unidentified fibrous inclusions. On the back, the crystal has a neat contact, of sugary aspect, from the lost matrix from which it seems to have separated very easily.

Specimen size: 12.9 × 12.6 × 11.6 cm = 5.08” × 4.96” × 4.57”

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.
