I went on a Carnival Cruise in Sept 2010, My husband purchased a 24 stone diamond ring paid 5000.00. Two months and 2 days later I looked down and a diamond was missing. I called diamond international and they said we only had a 30 day warranty. I was haeart broke. I ask if I could buy an extended warranty and they said we don't sell one. This is a crock. Carnival shouldn't promote company's that don't stand behind there product . This is a lot money to spend and then two months later have to do repairs. If any one knows of a company that I can buy insurance on my ring that will cover repairs incase another diamond falls out. read full review »
