Bi2S3
Bismuth SulfideBismuthinite is an important ore of bismuth. Sprays of steel gray prismatic bismuthinite crystals radiate outward from a common attachment point in the more spectacular specimens of this somewhat rare sulfide mineral. These specimens can not help but be compared to specimens of stibnite. It is difficult to distinguish from the similar looking and closely related antimony sulfide. Bismuthinite is heavier than stibnite and on closer inspection of the crystals, there exists a noticeable difference with bismuthinite’s having straighter, flatter faces. In massive form the confusion is even more pronounced, but bismuthinite is not associated with the typical antimony or arsenic minerals to which stibnite is so commonly allied.

D.R. Congo, Africa.Carrollite was discovered in Carroll County, Maryland, and recognized as a mineral species in 1852. Carrollite is collected for its mineralogical rarity, rarity of sizeable crystals, unusual chemical composition (relatively few cobalt-bearing minerals). Also it’s high degree of cubic-crystal development, and associations in composite specimens with such minerals as quartz and calcite.

Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Chalcedony is a variety of Quartz. A general term for all varieties of quartz that are made of microcrystalline varieties of quartz. Examples are the different types of agate, jasper, chert, chrysoprase, onyx, pietersite, etc.
Mentioned by Agricola (1546) of a stone named for the town of Chalcedon, and is a district within the city of Istanbul, Turkey.
MANGANESE
MnManganese is named from a corruption of the latin word for magnestism; magnes, in allusion to its prinicple ore’s magnetic properties. Manganese crystals have yet to be found in nature, therefore it is technically not a mineral. Laboratory grown specimens can look like a natural stone.
The element manganese is an essential element in people’s daily food consumption and has several industrial uses. Manganese is used in steel alloys to increase many favorable characteristics such as strength, hardness and durability. In fact steel can not be produced without manganese; it is an essential ingredient in the process. Manganese is also used to colour glass an amethyst colour. That is not so surprising since manganese is the trace element responsible for quartz’s purple variety, amethyst.
Manganese colouring ability in minerals is well known and appreciated. Manganese is chiefly responsible for the wonderful colours in rhodochrosite, purpurite, rhodonite, serandite and spessartine to name a few. Unfortunately most manganese oxide minerals tend to be black. Manganese is extracted from the ore minerals of pyrolusite and rhodochrosite. Manganese nodules on the sea floor may one day provide an economic ore source.
