How can I lean to tell the difference between cubic zirconia, diamond, and other stones? According to my internet research, cubic zirconia has more "dispersiveness" and "fire" than diamond, but diamonds have more "brilliance" than cubic zirconia. Can I train my eye to tell the stones apart with those properties? What does the "brilliance" look like, and how does that differ from "dispersiveness" and "fire"? Any other tips for differentiating stones used in jewelry would also be welcome. For example, if you have tips related to rubies, emeralds, or pearls, please share!

I recently purchased some loose gems and now I would like to make them into jewelry. How much does this kind of thing usually cost? Will just any jeweler do this or do I need to find a specific type of jeweler? Do I need to insure them before bringing them to the Jeweler? I'm not really into the bling, so this is all new to me.
