If I'm sure I'm buying a diamond & the (pro) seller thinks I'm buying glass , I keep my mouth shut (or ask 'stupid' questions) .
If I'm selling , I'll tell the buyer everything that I know to be true about the item (that makes only one simple true story to remember) ; does not matter to me if it's in print , media or simply words .
When selling , I think it's easier to call it like it is , in all cases , esp so if doing otherwise would be intentionaly deceptive .
I personally remember (& do repeated business with) honest sellers way better than all others , where ever they're found .
Goes to show that I'm fond of rare things ....
I save the duplicity , if useful , for when I'm buying .
I think I'd rather be known as an honest seller , v.s. a crafty buyer , though .
But then again , crafty buyers really don't want to be known as such ...
My personal model is that : the real $ is to be made in the buy , not the sale :
the real reputation comes from an honest sale .
