I'm cruising this spring and just remember hearing ALL about Tanzanite on our eastern caribbean cruise last fall. "It's so rare, but we still have a few for you to purchase though". The stuff was EVERYWHERE in St. Thomas and just wanted to know the REAL scoop vs the store paid (non-DCL employee) shopping consultants. It's pretty, but I'm concerned it's just overpriced CZ in different colors. Thoughts? I don't really have a trusted jeweler here locally so aside from shopping the chain stores and getting a sales pitch, I don't really have a go to person here.
