He is the fourth-generation owner and proprietor of Ruby Jewellers, an age-old gem and jewellery business in Colombo. Ruby Clement comes from a family of mine owners, gem collectors and Jewellers. Ruby’s father, grandfather and great-grandfather were all respected gem merchants in Rathnapura, Balangoda and Colombo. Rathnapura, meaning the “city of gems” and Balangoda are home to a vast majority of gem mines in Sri Lanka. Having his jewellery business established in Colombo, Ruby Clement sources most his gems from Rathnapura and Balangoda regions.

Born in 1956, Ravindrath Perera (Ravi) started his career as a gem cutter at a local gem merchant in Colombo. After learning the gem cutting trade for three years, he worked at a gem mine in Rathnapura to gain hands-on experience in gem mining. There he met a gem merchant from Rakwana who saw Ravi's cutting skills and invited Ravi to work at his Jewellery store where he worked for two years. For ten years since 1986, Ravi worked as an independent gem cutter and freelance lapidarist taking orders from multiple gem merchants and individual clients. In 1996, he left Sri Lanka for Tanzania where he worked as a gem valuer and a professional gem cutter. After gaining valuable experience working in the gem trade in Tanzania, he returned to Sri Lanka in 2001 and re-started his small business of gem cutting, valuation and gem trading in Colombo. While running his small business, he taught gem cutting students at Gem Red School in Beruwala, a scenic coastal town south of Colombo.
Apart from his main profession, Ravi is a talented Singer and a Guitarist who frequently receives invitations to perform at events and parties in the city. Ravi currently works at Ruby Jewellers as the principal gem cutter and a valuation specialist.
