Ok, for all non-Americans who don't know about the double ring...(Jason is extremely confused)...this is what I IM'd him...so enjoy!
ok...a girl wears one of four rings...a purity ring (meaning she's waiting to have *gasp...gonna say it* sex until marriage...a promise ring (meaning she's dating someone and can't quite afford an engagement ring), the diamond, or the engagement ring...and then the wedding band...they can be worn any way also...
the purity ring stands alone, the promise and engagement rings can be worn on the same hand, but the engagement and wedding band definately go on the left hand
