I want to thank Clare Appleyard and Katannuta Diamonds for their excellent service and product quality. My ring looks fantastic and was made exactly the way that I wanted it. I will pass your details on to friends and family as I believe everyone should find the same pleasure that I experienced in my engagement process.

I bought a diamond and platinum ring from Katannuta Diamonds from overseas and was very impressed with the service. Clare Appleyard was professional, friendly and helpful over our email and Skype communication. I arrived in South Africa on a visit from Western Australia (where I live), and when I received the ring, I was delighted at the beauty and quality of the design and its workmanship. It was not at all what I had imagined – it was far more beautiful! I can certainly recommend Katannuta Diamonds for their professional service tailored to individual taste and requests.

Buying a diamond engagement ring can be a nerve racking experience, but Clare Appleyard of Katannuta Diamonds made everything simple and easy for me. They gave great advice on diamonds and engagement rings and went out of their way to fit in with what I wanted. When I gave then really tight deadlines, they delivered. I would recommend them to any of my friends.
