EBAY SELLER PROTECTION IS GARBAGE!
I sold a stone with a validated certificate stating about the stone as well as photos of the item. The buyer opened a claim saying its not as described and so I must issue a refund because ebay says in 'item not as described' cases they side with the buyer regardless of your documentation!
WHATEVER YOU DO, DO NOT SELL ON EBAY!
IT WAS MY FIRST TIME AND *******% MY LAST TIME.
