What is a gemstone?
A precious or semiprecious stone, especially one that has been cut, polished, and used in a piece of jewelry. Source: www.wikianswers.com
How are gemstones mined?
Depends on what the mineral is, and where it is located. Some are mined by conventional surface mining with power shovels, some are mined in underground mines, and some are mined by drilling a shaft, and pumping a solvent (maybe water) into the ground- the mineral is dissolved in the solvent, and pumped back up again. It is then extracted from the solvent. Source: www.wikianswers.com
Can all minerals be gemstones? Explain.
Most minerals are not considered to be of gem worthiness because they are too soft or brittle. Source: www.wikianswers.com
