I just purchased a necklace with diamond pendant (.577ct/round/H&A/ideal/VVS2/H/AGS cert). Based on the average prices I dug up here, I seem to have paid my local jewler by ~$700 compared to internet prices. I don't mind paying a little more to my local merchant but this seems excessive (price was $2,700 + necklace + tax).I understand that the net prices are just for the diamond itself, so how much should be factored in for setting the diamond into a pendant? How much should be factored in to support one's local merchant? What I'm trying to figure out is by how much I really overpaid, if at all.Thanks in advance for any information.
