Diamonds of Africa
40 Years Experience in the Diamond and Jewellery Business


Peter Winhall and Sean de Stadler are highly regarded within the industry for their uncompromising ethical standards, and between them they have more than 40 years experience in the diamond jewellery business. Peter Winhall's contribution to the industry was recognised more than ten years ago when he was invited to become a member of the prestigious Be Beers Carat Club. Both partners have always believed in the importance of product knowledge in this specialist industry, and this led to an involvement as expert witness in litigation matters. Their qualifications are extensive and besides the Retail Jewellers Diploma, and diploma in antique jewellery, they include the following:

  • Gemological Institute of America (GIA) Diamond Certificate
  • Gemological Institute of America (GIA) Coloured Stone Certificate
  • Certified Master Valuator (Master Valuator Program) USA
  • Certified Evaluator (Gemmological Association of South Africa)
  • Rough Diamond Evaluation (Diamond Education College)

All staff are highly trained and have all had internal and external jewellery, diamond and gemmological training.
