I've really not been having good luck with eBay lately...I'm completely ready to give up! Around 6 weeks ago I purchased what I thought to be a white sapphire ring from eBay for £315. The seller specialises in estate jewellery, and I had complete confidence the item was as described. It arrived in the mail several days later, and was even more gorgeous than in the photos. Fast forward to last week, and I took the ring into a very reputable jeweller to get a valuation. They called me today to tell me that the stones were actually cubic zirconia, and therefore not really worth carrying out a valuation on I've immediately contacted the seller, but I've just had a thought...what if he thinks I've done a bait and switch? I have no way of proving that the stones weren't white sapphires when he posted the ring. I've also already left good feedback for the seller. Is there any hope I might get my money back?
