Not sure this is really going to help but, there is a little jewlery shop in Fidos that the lady will custom make jewlery for you. I saw what could be used as wedding bands there, and perhaps if you and your fiance talked with her, she could make something special for you. There is a band that plays there all the time called Barefoot Skinny, and I believe the lady who owns the shop is Barefoots wife. I may be wrong, so don't hold me to this. At the very least, you could talk to her, and she could maybe point you in the right direction if this is not something she can do. Good Luck and congratulations. How about a wedding in Belize?
