Lost blue bag with contents including ring

I lost a blue plastic bag with a white logo of the Dutch store Albert Heijn on it, around the Victoria Coach Station. Inside there was a pair of Hoka running shoes, a pair of red gloves, a daylight-lamp, a Dutch book in a paper bag and a silver coloured ring with a turtle on it. I might be forgetting something. The ring has a lot of sentimental value, it would mean so much to me if someone is able to return it to me.
