Gold-tone crescent necklace with sapphire charm

I lost my gold-tone crescent necklace yesterday around 3pm near the Anchorage Museum at Rasmuson Center on 625 C St. It's a slim curb chain about 20 inches long, with a small crescent moon pendant that has a tiny sapphire set at the tip. The back is engraved with a single initial 'A'. The chain looks slightly worn but still in good condition. It has sentimental value; my late grandmother gave it to me, and I've worn it almost every day since. If anyone found it, please let me know; it means a lot to me.
