Silver-tone necklace with heart pendant and initials

I lost my silver-tone necklace yesterday around 3pm near the Target on McHenry Avenue in Modesto. It's an 18-inch snake chain with a small circular heart pendant; the pendant is brushed silver with a tiny blue sapphire in the center and has my initials 'A.B.' engraved inside the clasp. The chain has a few scratches from daily wear, but everything else is intact. It means a lot to me—it was a gift from my grandmother and it helps me feel close to her. If anyone found it, I’d really appreciate returning it; I can meet up or pick it up wherever convenient.
