Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. Density: 4.48 g/cm³ Optical properties: biaxial positive Crystal class: Dipyramidal (mmm); H-M symbol: (2/m 2/m 2/m) Crystal habit: Tabular parallel to base, fibrous, nodular to massive Specific gravity: 4.3–5

Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air. Symbol: Pr Electron configuration: [Xe] 4f36s2 Atomic number: 59 Atomic mass: 140.90765 u Discovered: 1885
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).
Graphite, archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. Under high pressures and temperatures it converts to diamond. Density: 2.09–2.23 g/cm3 Mohs scale hardness: 1–2 Optical properties: Uniaxial (–) Crystal system: Hexagonal Space group: P63mc (buckled) P63/mmc (flat) Crystal habit: Tabular, six-sided foliated masses, granular to compacted masses
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately hard, malleable, and has a high melting point. Symbol: Th Electron configuration: [Rn] 6d27s2 Atomic number: 90 Atomic mass: 232.03806 u Discoverer: Jöns Jacob Berzelius
Wolframite, WO₄, is an iron manganese tungstate mineral that is the intermediate between ferberite and hübnerite. Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives. Crystal class: Prismatic (2/m); (same H-M symbol) Crystal system: Monoclinic crystal system Crystal habit: Tabular to short prismatic crystals Space group: P2/c Streak: Reddish brown Color: Grayish to brownish black
Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
Cassiterite is a tin oxide mineral, SnO₂. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today. Crystal system: Tetragonal crystal system Crystal class: Ditetragonal dipyramidal (4/mmm); H-M symbol: (4/m 2/m 2/m) Optical properties: Uniaxial (+) Mohs scale hardness: 6–7 Unit cell: a = 4.7382(4) Å, c = 3.1871(1) Å; Z = 2 Did you know: Cassiterite sometimes is used as a minor gemstone, but mostly for the collectors of minerals.
