Silver ring with emerald stone, initials inside

I lost my silver ring with an emerald centerpiece yesterday around 3pm near the Anchorage Museum on 7th Ave downtown. It's a slim, 6mm band, sterling silver, with a small oval emerald set in a subtle bezel. On the inside there are the initials 'PK' engraved, and there’s a tiny scratch by the setting from a fall last winter. It means a lot to me because it was a gift from my grandmother; it has sentimental value and I really hope to get it back!
