Mineral specimens search results for [ Quartz ]

Very well-developed Quartz crystal with parallel growth on the terminal faces and several very sharp, black, and shiny crystals of Cassiterite. The Quartz is partially coated with small lenticular crystals of Siderite, in turn covered with very shiny microcrystals of Pyrite. Like all specimens in Raúl Sanabria's collection, it was chosen with great care, always aiming to have something special that sets it apart.

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.

MRA98CD4: Quartz with Chlorite inclusions and Albite

Plate formed by Quartz crystals arranged in a very aerial manner with clear development of the prism and the perfectly sharp terminations, translucent and with abundant inclusions of dark green Chlorite concentrated in the centers of the Quartz prisms, and which in turn are partially covered by very clear, practically transparent Albite crystals. An alpine classic from a well-known mineralogical area of Switzerland.

WRA96CD2: Quartz with Fluorapatite, Siderite and Pyrite

Well-developed Quartz crystal, translucent and shiny, coated with shiny and bluish Fluorapatite crystals; with Siderite and a coating of small Pyrite crystals on the back. Noteworthy, in addition to its beauty, are the Fluorapatite inclusions inside the Quartz crystal, which, due to their partial fusion at the Quartz formation temperature, have a very unusual appearance. Like all specimens in Raúl Sanabria's collection, it was chosen with great care, always aiming to have something special that sets it apart.

MBR87CD3: Quartz with Siderite

Druse formed by Quartz crystals, on matrix, very elongated and aerial, water-clear and perfectly sharp, with endings that show the Dauphine habit, interpenetrated by ocher-brown rhombohedral Siderite crystals forming a classic alpine association for these two species and with the Quartz clearer than is usually the case for this locality.
Le Trou des Chasseurs, Vizille, Grenoble, Isère, Auvergne-Rhône-Alpes France (12/2011)
Specimen size: 8.8 × 6.2 × 5.3 cm = 3.46” × 2.44” × 2.09”

WZP50CD2: Quartz with Siderite and Muscovite

Group of hyaline Quartz crystals, all doubly terminated, with very defined faces, and some with polycrystalline terminations. They have a sharper and 'cleaner' appearance than the typical Panasqueira quartz, with coatings of Siderite and leafy aggregates of Muscovite. Like all specimens in Raúl Sanabria's collection, it was chosen with great care, always aiming to have something special that sets it apart.
