Gemstone and Jewelry Presentation Script

I need someone to write several short scripts about gemstones and jewelry that include interesting facts about where gemstones are mined, celebrities who have worn them, and stories/legends associated with them. The person working on this will need to be comfortable with using the Internet to research specific gemstones in order to find the information to use to write this script. The finished product will be a Word Document with a 450-600 word "script" about each of the following topics: White Diamonds, Colored Diamonds, Tanzanite, Rubies, Emeralds, Sapphires, Difference between Natural, Synthetic and Imitation gemstones, typical steps followed from the mining of a gemstone until it is set into a piece of jewelry. The "tone" of the scripts should be conversational, yet educated. Sources will need to be cited at the end of the document.
