If so, how was your experience? Did you use best offer?
I've had my eye on a ring mount for an OEC that I've had sitting around for several years waiting for a home, but feel it is way over priced and don't want to offer a ridiculously low price and offend them.
I bought a gorgeous band with french cuts from them for Christmas last year. It wasn't a steal by any means, but it's hard for me to find antique rings in my size (4) and I really loved it so I went for it anyway. They are not (or weren't with me) very flexible on price- I offered 20% less than what the price was originally, and they rejected that and we settled on around 10% I think eventually. HTH!
