I recently bought an emerald cut diamond from Quality Diamond dealing with Paul and Daniel. I was very impressed by their approach, offering advice on things to look for including and beyond the four Cs, like ratio, symetry, polish and diamond score. The result was a beautiful diamond that ticks all the boxes. The stone was delivered on time, beautifully packaged and including all the relevant certification for the stone and an insurance valuation. You can feel safe in their hands, these people have a great work ethic and integrity in business, and they exemplifiy excellence in customer service.
