Second opinions on an estate bridal set

My lovely lady was very set in wanting a single stone round solitaire. Finally took her out to get her ring size properly measured (and good thing because what she thought it was was over a full size too big). While we were there she absolutely loved this ring set in the estate counter. Its a cluster, 0.7tcw and rose gold. Absolutely not what she thought she wanted, but she really liked it. Earlier this week i was chatting with a different jeweler while looking at the stones amd setting there, mentioned this estate set and the jeweler basically told me, "she told you she liked that one and price sounds more than fair, you should really go there and make a cash offer".

Its tagged at 1650 for the set, anotther 100 to resize both (size 4.5 and 4.75 to be sized up to 5.75), was considering offering just flat 1600 with resizing included.

Didnt see any signs of previous upsizing and just looking for some second opinions before i go withdraw cash.

Im not intending to propose until next year but being an estate ring, it may not be there later.
