Looking for jeweler in Oxford, England

[Vintagedream]

I’m an American living in Oxford for the next 6 months. I’m looking for a good jeweler to take a look at my ring and make sure the stone is secure. As well as discuss a possible reset. I just have a feeling it needs to be checked so I’m not wearing it (which also makes me nervous because I don’t want to lose it!) I’d love to find an excellent jeweler While we are here. Thanks!
