What they say
I have a four carat Victorian ring which I purchased a few years ago. It’s always been my dream to own a large solitaire diamond, I was elated with the ring Peter sourced for me as I was very specific about what I wanted. The stone is high quality and was certified by the GIA. I was also given a valuation certificate for insurance purposes. The ring was excellent value and the service I received was exemplary. I still use this company to check the setting every couple of years as I trust them completely. I also part exchanged a smaller ring for a very good price. I wouldn’t hesitate to buy from Peter again in the future
Peter found me the perfect engagement ring. Great friendly service.
