I have just purchased 2 rings from Jason (actually Gemma) and what an incredible experience! Gemma was fantastic and very easy to deal with. Jason was operating in the background (we didn't see him although he was involved in the process). I have picked up ring one and one to go as it is getting changed from white gold to yellow and, from my experience so far, I couldn't recommend them highly enough, apart from the service, the quality of the ring I have picked up is top grade.
