Is it like Marilyn sang ..."diamonds are a girl's best friend!"
or
her B.O.B. (battery operated boyfriend)?
I think until we can get our Mr. Johnson to vibrate at 1000 times a second like her B.O.B., we know what the answer is :-(
Diamonds are overrated and BOB's are nice, but nothing beats the real thing.
I'm an emerald gal myself.
