Eudialytes are mildly radioactive, but wearing or handling pieces under 5 cts (1 gram) should pose no health risks. On the other hand, holding a eudialyte sphere of 5,000 cts (1 kg) — a very large piece, indeed — would expose you to 2.40 mREM per hour. To put that in perspective, the average annual estimated radiation exposure in the U.S ...

Some of the eudialyte-like structures can even be more complex, however, in general, its typical feature is the presence of [Si 3 O 9] 6− and [Si 9 O 27] 18− ring silicate groups. Space group is usually R 3 m or R -3 m but may be reduced to R 3 due to cation ordering. Like other zirconosilicates, the eudialyte group minerals possess ...

Uranium was mined from 1947 to 1990 from mines in Saxony and Thuringia by the SDAG Wismut. It was mostly used by the Soviet Union to build nuclear fission weapons, also as fuel for nuclear power plants. In West Germany more limited mining took place at Ellweiler, Rheinland-Pfalz (1959–1964), and Menzenschwand, Baden-Württemberg (1961–1991).

Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminium hydroxyl sorosilicate), caused by small amounts of vanadium. Tanzanite belongs to the epidote mineral group. Tanzanite is only found in Tanzania, in a very small mining area (approximately 7 km (4.3 mi) long and 2 km (1.2 mi) wide) near the Mererani Hills.
Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca 5 (PO 4) 3 F (calcium fluorophosphate). Fluorapatite is a hard crystalline solid. Although samples can have various color (green, brown, blue, yellow, violet, or colorless), the pure mineral is colorless, as expected for a material lacking transition metals.
