We will need to personally inspect the diamond before we can make an offer, but can give you a range, if you provide us the copy of your GIA certificate. We do not buy any gold, jewelry, or small side diamonds, only single diamonds over .70 carats. We do all of our diamond buying by GIA trained gemologist and have offices in CA and beyond.
