Bought back in 2016 I believe. I no longer have the paperwork from my ex unfortunately so you're going to have to take my word here. You might be able to look up additional info at Zales if I give you his name? Unsure but he bought the ring for $2,500. Obviously it isn't worth that currently, so priced at $400. 

The ring really needs to be serviced and a deep clean. I'm just trying to get rid of it so it no longer sits in the bottom of a drawer.
