GIN is a Get It Now option U can add by clicking the 'Edit' button at the top of ur auction page, scroll down & click on the 'Advanced Options' bar U see on the left. Then U can put in the maximum amount U are willing to take for the ring so a winner can skip the bidding & get the ring for ur asking amount. However, Listia takes 50 credits for using this option, non returnable if GIN is not used, & returned if GIN is used but then Listia takes a percentage of ur GIN credits. While ur editing in this section, U can also extend the days of this auction if U wish, in case U don't want to do a GIN or no one uses it, then there is more time for searchers to find ur auction & u'll get higher bids.
The inside of the band has markings but too small to make out. I've tried !!! I'm thinking it's gold filled because the diamonds are pretty but not real.....
