So what do you say to the guy who just bought a 20,000 dollar Rolex,or the guy/gal who blew 50 large,on a new Lexus.Should I tell my future son in law not to spend serious bucks on an engagement ring,for my daughter?Diamond pricing IS controlled by a cartel,and even they are a rip-off!If I opened my mouth,in that scenario,I would not have a home(would be kicked out by wife AND daughter)to house my rather cheap 3800 dollar cartridge,that I just got(large discount,of course)!!
