I  have to investigate a topic concerning the mining, processing, and retail marketing of gemstones, and report on what I find.

My topic is .....Specific minerals chosen as gemstones.

Well, gem stones are chosen for their beauty and color and rarity. Other qualities might be considered. For instance, unstable isotopes would not be used, radioactive would not be used, brittle minerals would not be used. Flint although very hard would not be used as it is common. So...that is just a start.
