In the early 90s, Riki travelled to India and was inspired by the jewellery manufacture and gemstone cutting in the Pink City, Jaipur.
On returning to South Africa, he began to apprentice as a diamond cutter and goldsmith before he decided to form his own company, built upon his vision of a unique, wholly South African product.
