Silver necklace with star pendant, Las Vegas

I lost my silver necklace yesterday around 3pm near the Bellagio fountains on the Las Vegas Strip. It's an 18-inch sterling silver chain with a small star-shaped pendant that has a tiny blue sapphire in the center. On the back of the star, there's an engraved initials 'M.K.' and the clasp shows a bit of tarnish from daily wear. It's sentimental to me - it's a gift from my grandmother and I wear it every day. If anyone found it, I'd really appreciate getting it back.
