VTG Tiffany & Co. Basics 1837 concave ring sterling silver, size 7.5

Tiffany & Co 1837 Basics sterling silver concave ring w/box, pouch and cleaning card. From my personal collection: purchased originally from the Downtown Portland Tiffany store. Size 7.5 (see picture of ring on Mandrel). Fits more like a 7.25 due to the thickness of the band. No longer fits my finger! Included in the purchase: bracelet, pouch, box, and Tiffany cleaning card. Please see all photos for measurements and condition. The ring shows regular wear and tear for its age, including minor scratching, etc. I wore this daily, until the ring would no longer fit.
