Cobalt blue vase with gold lotus motif

I lost my cobalt blue ceramic vase yesterday around 3pm in the Las Vegas Arts District. It's a 12-inch tall handmade piece with a glossy cobalt glaze and a slender neck, decorated with a gold lotus motif. The base is signed 'L. Chen' and there's a tiny chip on the rim at the left edge—easy to spot if you know what to look for. I had it in a light gray felt sleeve inside a clear display box while I was setting up at the Art Square courtyard off Main Street. It was a gift from my grandmother and means a lot to me, so I’d be incredibly grateful to have it back; I can bring photos and offer a reward.
