Tiffany & Co. Sterling Silver 925 Double Heart Tag Necklace

Tiffany & Co. Sterling Silver 925 Double Heart Tag Necklace, with Tiffany pouch. Engraving on one heart says “Please Return to Tiffany & Co New York 925”. My lighting is horrible and the necklace needs to be cleaned, but it is silver, one pic of the mark has been included. Pre-owned, again, needs to good cleaning. Very sweet, delicate necklace. I have had it in my jewelry box for years, never wear it, the clasp is incredibly small, I can no longer take it on and off myself.
