Tiffany & Co. 18K rose gold stackable diamond solitaire ring.

Tiffany & Co. 18K stackable diamond solitaire ring in rose gold, size 5.75. The diamond is .18 carat and it is set in a platinum shank. I've had it for a long time, it was too big & I had it resized at Tiffany & Co. in New York. I don't have the original receipt, but I have the receipt from when I took it to the store where they test & check it in front of you before accepting it for resizing. Comes with Tiffany & Co box.
