Hair blazers green

Does any know how much I could sell this ring for? - how much does a gold ak weight

My ex-finance me this ring, and I intend to sell them and asked what you think it works. I think the band is 14 carat gold and instant messaging are not sure how many carats of diamonds.

I have a photo reference.
