Silver necklace with heart pendant and sapphire

I lost my silver necklace yesterday around 3pm near the Starbucks at Valley Hills Mall in Hickory. It’s a thin sterling-silver chain, about 18 inches long, with a small heart pendant that has a tiny blue sapphire in the center. The back of the pendant has a faint scratch and the clasp feels a bit worn from daily wear. It’s a gift from my grandmother, so it means a lot to me and I really need it back. If you found it, I’d be incredibly grateful to get it back.
