A little story about the cruise pier jewelry shops. My MIL was with us in Coz and we were at one of the cheaper upstairs shops and she just loved what they told her was a real sapphire. I warned her it wasn't, sapphires that big are rare and EXPENSIVE and they wanted $400 for this ring. I walked out of the shop and looked for it at some others, there it was...went back in and warned her again not to buy that all the other shops had this ring (NOT a genuine sapphire obviously). She argued that she just loved it and bought it. Months later she had it checked at the jewelers and sure enough, simulated. That ring wasn't worth $100 much less 4. So be careful with shops at the pier.
