TB91AG1: Quartz (variety amethyst)
Large crystals of amethyst, different than the classic amethysts of Las Vigas, with thicker and slightly tapered crystals and zoned color, very intense in the first generation of the crystal and colorless or white in its last growth phase. A classic of the past from the collection of José Luis Vallecillo.
Amatitlán, Municipio Eduardo Neri, Guerrero  Mexico
Specimen size: 17.7 × 11.5 × 6.7 cm = 6.97” × 4.53” × 2.64”
.
ERB72AO9: Quartz (variety amethyst)
Obtained at Ste. Marie 2022 Group of Quartz crystals with very sharp crystal forms, with scepter growths, with a relatively short prism, translucent and with an intense deep violet color. The specimen comes from a find made in a locality practically unknown to date.
Berjé, Aïr Massif, Agadez Region  Niger (08/2021)
Specimen size: 14.2 × 12.3 × 8.6 cm = 5.59” × 4.84” × 3.39”

Main crystal size: 5.3 × 5.3 cm = 2.09” × 2.09”
.
FG90: Quartz (variety amethyst)
Amatitlan gave the largest doubly terminated Amethyst crystals in the world. Unfortunately most of them were damaged with broken or significant dings at the top of the crystals. Just a few specimen were saved in good shape. Again, Martín was in the right place at the right time and luckily he got a very esthetic one without significant damage. Plus this specimen has two main doubly terminated crystals joined by other smaller crystals. As you can see in the photo the specimen looks great!
Amatitlán, Municipio Eduardo Neri, Guerrero  Mexico
Specimen size: 9 × 8.8 × 6.2 cm = 3.54” × 3.46” × 2.44”
.

MF50AA9: Quartz (variety amethyst)
Two parallel stalactitic growths of very sharp and bright crystals, with a very intense, deep and uniform color, that are on a base of white chalcedony. The sample is from a recent find in a new quarry at the locality.
Amarilla Quarry, Catalán Grande area, Artigas Department  Uruguay (03/2014)
Specimen size: 12.4 × 8.8 × 5.4 cm = 4.88” × 3.46” × 2.13”

MB93AA9: Quartz (variety amethyst)
Perimorph growth of very sharp and bright crystals with a very deep violet color, very rich with oxide inclusions and with recrystallized hematoid Quartz microcrystals on the edges. The amethyst grew coating a group of Calcite crystals, subsequently dissolved and completely missing, that left a big cavity with geometrical forms.
Amarilla Quarry, Catalán Grande area, Artigas Department  Uruguay (03/2014)
Specimen size: 22.5 × 10.3 × 5.4 cm = 8.86” × 4.06” × 2.13”
.
MB99I0: Quartz (variety amethyst)
The quality of its color is extraordinary. Crystals have different intensities of color on the prism and the rhombohedron, it is more intense on the terminations. The group is a stalagmite which once covered a hexagonal crystal of Calcite, now gone, but it left a mold in the center of the specimen. We note the precision of the quarry’s name, until now very difficult to determine on Uruguayan specimen.
The specimen has been reviewed, photographed and published as a new discovery in the magazine ‘Mineral Up’ on page 54 in number 2007/1.

Specimen size: 10.5 × 7.9 × 8 cm = 4.13” × 3.11” × 3.15”
.
MN49R8: Quartz (variety amethyst)

.
NA10L6: Quartz (variety amethyst)
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.
Soliva Quarry (AVE Quarry works), Can Sala, Riudarenes, Comarca La Selva, Gerona / Girona, Catalonia / Catalunya  Spain (2006)
Specimen size: 7.6 × 5.1 × 5.2 cm = 2.99” × 2.01” × 2.05”

RV76H7: Quartz (variety amethyst)
Beautiful miniature. It is a group of crystals having an extraordinary deep color. Faces and edges are so sharp that they seem polished. The locality itself is very original.
Eonyang, Gyeongsangnam-do  South Korea (±1974)
Specimen size: 3.5 × 2.6 × 1.6 cm = 1.38” × 1.02” × 0.63”

.
TV62H8: Quartz (variety amethyst)
A nice miniature, very esthetic, forms a crown of crystals of excellent transparency, luster and color typical of the samples of this locality. The crown of violet crystals strongly contrasts with a central nucleus of clearer crystals practically uncolored.
Kakamunurle Quarry, Karur District, Tamil Nadu  India (2005)

.
NB57F0: Quartz (variety amethyst)
The most notable thing about these crystals is the way the rhombohedral faces of the termination are much larger than the prism faces. The color is intense and the coloring is not evenly distributed within the crystals. The rear has re-crystallized.
Mas Sever Quarry, Massabè (Mas Ceber), Sils, Comarca La Selva, Gerona / Girona, Catalonia / Catalunya  Spain (2004)
Specimen size: 4.5 × 3.5 × 1.5 cm = 1.77” × 1.38” × 0.59”
.
JA13E5: Quartz (variety amethyst)
This elegant specimen appealed to me because of its nice color hints. With thin matrix on which the, sometimes doubly terminated, crystals of amethyst grow.
Piedra Parada (Las Vigas), Municipio Tatatila, Veracruz (Veracruz de Ignacio de la Llave)  Mexico (±1979)
Specimen size: 2.9 × 2.7 × 1.4 cm = 1.14” × 1.06” × 0.55”

Sharp crystal with a deep color on a small matrix of Epidote, but the highlight of this specimen are the series of phantoms close to the top of the specimen. It is as good as it looks (or maybe even better)
Piedra Parada (Las Vigas), Municipio Tatatila, Veracruz (Veracruz de Ignacio de la Llave)  Mexico
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.
