This Quartz crystal stands out for the definition of its forms and its purity, transparency and incredible luster. A collector’s choice specimen.
Cavradi gorge (Val Cavradi), Municipality of Tujetsch (Tavetsch), Surselva District, Grischun (Grisons; Graubünden) Switzerland (±1947)
Specimen size: 4.8 × 2.5 × 1.6 cm = 1.89” × 0.98” × 0.63”

RJ26G2: Quartz

The crystal is perfectly transparent; its faces are sharply defined, with an "Alpine" quality, on a matrix with a fibrous silicate, probably Actinolite which penetrates into the Quartz as an inclusion.
Cavradi gorge (Val Cavradi), Municipality of Tujetsch (Tavetsch), Surselva District, Grischun (Grisons; Graubünden) Switzerland (±1949)
Specimen size: 6.1 × 3 × 2.5 cm = 2.40” × 1.18” × 0.98”

TT86E0: Quartz

Although many people call this "beta" Quartz, it is not. They do so because it resembles beta Quartz, which means that there are no prism faces, only pseudo pyramidal faces. Dalnegorsk is one of the localities that are well known for this called "beta" Quartz (although of course them are not a specie) Given the brilliance, definition of the faces, and esthetics this one could be considered to be among the best.

TN96G4: Quartz

Even considering that the principal interest of this big group of Quartz crystals is centered on the locality, worldwide famous by its gold telluride and actually re-exploited, we must also emphasize the morphology of the group and of the crystals, which on their top faces have a supremacy of one of the rhombohedrons, giving a first appearance that they terminate only with three faces instead of the usual six.

JFD148AO7: Quartz (doubly terminated) with Baryte and hydrocarbon inclusions

Why did I choose this Berbes Quartz? It is beautiful, yes, and it has inclusions and some of them are mobile, but although it seems silly, I kept it because it was associated with small fragments of Baryte, which, curiously, is unusual with Berbes Quartz.
