Want to make you wife/girlfriend happy?
When I was doing the jewerly gig we had folks asking me to mount big cubic zirconias in convincing mountings all of the time. I can spot a fake a mile away but most folks could not tell the diff between a diamond and a cz till they get to the cash register. An avarage 1ct stone of superior quality would cost us around 3k wholesale. The same size cz, and I am NOT making this up, under 10 bucks. Needless to say which one I prefer.
I'd rather spend the money on my Duster; still less expensive than a woman! -LY
