Hand-painted cobalt vase, 10 inches tall

I lost my hand-painted ceramic vase yesterday around 3pm near the Smith College Campus Center on Main Street in Northampton. It's a handmade Riverbend Pottery piece, glazed cobalt blue with tiny gold speckles and a slightly irregular rim. It's about 10 inches tall and 5 inches across at the widest point, and there's a small mark on the base that reads 'A. Rivera.' The glaze has a subtle crackle, and the piece is otherwise in good condition. It was a gift from my grandmother and means a lot to me — I'm really hoping someone picked it up and can help me get it back. If you found it, drop me a note here so I can verify the base mark.
