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.

My sister had organized an appointment with Clare Appleyard and Katannuta Diamonds regarding a tanzanite pendant and I joined them or the appointment. With Clare's professional knowledge and advice and after looking through some catalogues we created a ring. The final product arrived it took my breath away, it was so much more than I had imagined. Thank you Katannuta Diamonds, I wear my ring with pride. I have also received many compliments. You will be seeing me again in the future.
