YC London

If you want bright & shiny this is the place, they have a vast selection of jewellery. The staff are very knowledgeable (so be careful what jewellery you walk in wearing!!)
As with most jewellers they stock rings, chains, earrings, bracelets, watches and so the long list goes on. The reason I went here is that they can create custom jewellery to your specifications, and most importantly work to your budget.
They were able to show me a good selection of items they had hand made for other customers and took me through the process of how they would make it. They have a few stories they throw in for good measures, which did make the whole process a little less painful. They provided me with good advice on my requirements and were able to give me a very good price for the item I wanted.
They have several photos on the wall of what I can only suggest are their celebrity customers, which is not a bad thing I guess. Do not worry though they do have many items which are what I would call normal prices alongside other items which, for my personal taste, are far to shiny.
If you like jewellery whether that be simple or that which is more on the bling side of things then this is the shop for you. It is definitely not your run of the mill jewellery shop, this has all the bling you could ever need.
