Fellows Auctions has a heaping handful of beautiful natural blue sapphire rings hitting the auction block this week for their May 15th Antique and Modern Fine Jewelry Auction. ย Their origins vary and so do their treatments, making some much more expensive than others. ย My absolute favorite is the first listed below, which is a natural sapphire originating from Sri Lanka set with a large gold halo accented with old cut diamonds. ย Click through each photo to go to the auction listings. ย Can you guess which sapphire is treated and which is not?
