I sent my 2.53ct sapphire and diamond Tiffany ring to be resized, unfortunately they scratched the sapphire,and have replaced it with a 2.83ct sapphire of "similar" quality (so I''m informed). Tiffanys now want to send the ring back to me, however I''m unsure if I should just accept this. The ring had a recent appraisal for $16,000 and was bought in 1998 from Tiffanys in New York.
Advice please.
