Some time ago a diamond dealer was cleaning out his desk (it must have been VERY dirty). He found an old wholesale price list for diamond. He sent it over to me via fax, so I’m posting it here for those who might find it interesting. This price list is from before the current GIA diamond grading scale was used.
Looks like you could buy a 1.5ct diamond, D color, Flawless clarity for $730 per carat… you will not get deals like that these days!
