Understanding there are about as many variables involved as possible, I am trying to figure out if a ring we’ve fallen for to celebrate my 50th is a bad buy or a good one. The main diamond is big (over 4.5 cts) and from what I can tell without seeing it in person (photos and 2 videos, one showing different lighting situations) it looks decently cut, and the form of cut is to my liking (square emerald with big windmills
). It has a GIA certificate, so I am pretty confident about the color and clarity being accurately, as well as the polish.
The thing is if I look at the PS price tables, I don’t think this stone is much below retail. It is a bit hard to know because there aren’t a ton of comps on the price table, and the ones there that can be tracked down have things like visible inclusions even in the VS range, where this one is eye clean.
It leaves me all in a muddle, is it true that the used discount on larger stones gets smaller because it can be just be sold as an unmounted stone? (This is what the vendor told us when we offered a price about 15% off the list).
TIA for your thoughts and much appreciated advise.
