A gemstone (also called a fine gem, jewel, precious stone, or semiprecious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. A fascinating sub-suite in Nobles collection is a group of minerals from the Mark Chance Bandy collection that he acquired years ago from one of Bandys nephews. The mineral group tantalite [TaO] is the primary source of the chemical element tantalum. By Class Carbonates Elements Halides The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. Coltan (short for columbitetantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The mineral name is derived from the term Cassiterides which was applied 'islands off the western coast of Europe' in pre-Roman times (the exact location of these 'islands' has been hotly debated over the years, current thought is that the source was probably mainland Spain and that even 2000 years ago, traders had a habit of providing misleading locality information to protect Cassiterite has been an important ore of tin for eons and is still the greatest source of tin today.
