Sterling silver ring with blue gem

I lost my sterling silver ring yesterday around 3pm near the Walmart on Pioneer Way in Moses Lake. It's a size 6 plain band with a small blue gemstone set in a simple bezel. The outer band has a delicate crescent moon engraving, and the inside is etched with the initials 'MB'. It’s worn and has sentimental value—my grandmother gave it to me and it’s all I have left of her. If anyone found it, I’d really appreciate getting it back.
