Hello everyone !! I accidentally posted wrong the first time so hopefully I do it right this time...
I was wondering if anyone has ever come across a Tiffany & Co. platinum with diamonds eternity band that happened to have a four digit number inside? Long story short, I just inherited a Tiffany & Co. platinum eternity band but have not actually seen it first hand. The reading of the will was this past week and I only got to see the GIA report for insurance purposes because the ring is still in the safety deposit box and will not be delivered to me until next week or so along with the other items that I had inherited. On the GIA report that I received it stated that the hallmarks on the inside were the copyright symbol Tiffany & Co. PT950 and then the four digit number. Originally I had only thought that Tiffany used serial numbers on their engagement rings but while browsing ebay I saw other vintage Tiffany platinum and diamond eternity bands that also had four digit numbers after the typical copyright signature. Obviously I hope that this is an authentic piece of jewelry but like I stated before I have no idea. Please let me know what you think since I honestly have no experience on this topic.
I think with a piece like this, your best option is to take it to a good appraiser and get a professional opinion.
