I'm wondering where the best place would be to advertise this piece of work for sell and how do I find out its current value. Thank you all in advance :)
Its 700ct hanging in a rosewood frame, about 54" x 35"
Heavy too! :p

How old is it? Do you know the name of the artist? Knowing those things would help in giving you the most helpful answer.

I can't see any artists signature on it, I have a jewel certificate from 1984 that lists it as
$3695.00 but that's about it, thank you for your time :)

Another resource that you might try, would be an auctioneer who maybe auctions off a lot of works of art.
