Selling gold ring (without certificate of authenticity)

Selling a gold and silver ring without certificate of authenticity as I lost it, I'm from Mollerussa and I can't travel, I'm asking 300 but I can negotiate the price, I'm selling the ring because it fell and I ran over it with the car, leaving it somewhat damaged on the sides For any questions or offers, please don't hesitate to contact me, I respond to all questions or offers but it may take at least a few hours to reply
