I found something interesting from thegemtrader, they called it ruby/blue sapphire

is it just me or the stone looks pink-blue rather than red-blue. Correct me if I'm wrong, pink corrondum is called pink sapphire instead of ruby. I found this stone after hitting the "Click Here for Our Latest Round of eBay Auctions!" button in thegemtrader website.
