A friend of mine mentioned something about rhenium (sp?) and their site mentions Dysprosium (Dy). Are these safe? Will they break easily?

I'm getting married next year and wanted something unique for a ring. I read on SlashDot last week that I could get an iridium ring from this company: http://www.americanelements.com. Has anyone ever bought one of these? Are they safe? Do they last? Can anyone suggest any other cool or exotic elements for wedding rings?
