Mass: 339 g
MIM number:1880
Grayish crystal, altered by the radioactivity of thorium, showing nevertheless some faces typical of the quadratic symmetry of thorite, isomorphous to zircon. This crystal is considered very large for the species. Because thorite is highly radioactive, specimens such as this one are often metamict: This is a condition found in radioactive minerals that results from the destructive effects of its own radiation on its crystal lattice. The effect can destroy a crystal lattice completely while leaving the outward appearance unchanged.

White marble cavity from the famous Carrara quarry in the Apennines, containing exceptionally pure doubly terminated quartz crystals. Apennines are a mountain range extending along the Italian peninsula from north to south for about 1200 km, through fifteen of the twenty Italian regions. Their genesis began about 20 million years ago and is still slowly ongoing. During this genesis, almost pure carbonate sediments which precipitated from an older shallow hot sea were deeply compressed and recrystallized in a first stage to form calcareous rock of what would become much latter the famous Carrara white marble which has been exploited since Roman times. In a second stage, higher pressures and temperatures reaching 400 °C, deformed and reorganized the crystalline structure of this rock, forming a metamorphic rock with a different structure, namely marble, which “design” and aspect have made so famous. It was during this second phase that, along thin white and crystalline bands, cracks and cavities opened in the marble, hydrothermal solutions seeped in and deposited crystallized quartz and other mineralogical species inside. While cavities and crystals are unforgivable defects in the cutting of marble blocks, they are also precious geological testimonies of the amazing laws of nature. The discovery in 1998 of an exceptional cavity containing this sample has been filmed during its opening with a diamond chainsaw along the front wall of the cave. In order not to damage the crystals, the recovery required several days of careful work, which made it possible to isolate this beautiful sample. The sawing marks are clearly visible on the external faces of this sample.

Black acicular goethite crystals closely packed in a shiny 7.1 cm diameter ball on a carpet of quartz crystals, some of which include fine goethite needles. The terminations of most of the crystals constituting the ball are platy while on the periphery of the ball they are in needles. The original deposit of this piece is worked for its numerous quartz geodes sold massively in Tizi-n-Tichka and elsewhere in the world. These are usually modest samples where the crystals of quartz are associated with fine goethite needles. Very sporadically balls of goethite crystals are found on quartz carpet: their extraction is not easy, and many balls are damaged. This sample represents the very high end of what has been produced by this mine.
