Engagement ring

A man walks in to a jewelry shop to buy an engagement ring. He comes across a beautiful band with a big rock in its center. "Excuse me sir" he says to the salesman, "How much is this ring?'

The salesman replied " Ah, that's a beautiful piece, it is costs $10,000."

"My God!" the man exclaimed. "That's a lot of money!"

"Yes, but a diamond is forever."

"Perhaps," the gentleman replied, "but my marriage won't last that long!"
