Our Story


SJ Gems was established in 2018 by Joe Liebenberg when he saw a gap in the market for a reliable coloured gemstone supply company. SJ Gems is run by Joe himself, ensuring only the best in quality and service available.


Who is SJ Gems? Joe Liebenberg grew up in Kimberley, South Africa. Being a historical mining town, he has always been exposed to gems and diamonds. In 1998, Joe obtained his rough diamond qualification from the Harry Oppenheimer Diamond School in Johannesburg. Later, Joe continued his educational path by obtaining gemmology qualifications from the Gemmological Institute of America.  Further experience was gained by working for Diamond and Gemstone companies across Africa and the East.


The popularity of semi-precious gemstones has increased enormously in South Africa over the past few years.   They offer a fascinating world of colour, emotion and eye-catching vibrancy.  When you purchase from SJ Gems, you will own a unique stone!   Coloured gemstones often have visible inclusions that tells you a “story” about the stone.   So, if you are looking for that Peachy Pink Morganite for your engagement ring OR a natural Ruby to bring you good luck, SJ Gems will help you find one.   We offer a safe, on-line purchase environment with high quality images to accurately represent the stone’s colour and clarity.   What you see is what you will get.  We also provide the option to have your gemstone certified with EGL Laboratories. SJ Gems aim to be your local supplier of ethically sourced gemstones.


SJ Gems collaborates with one of the most trusted jewellery manufacturers in SA. They are responsible for many well-known brands in the South African market. Technology has certainly changed over the past years and gone are the days of old fashioned “bench jewellers”. Simply put, they cannot compete with new manufacturing processes. If you are concerned about quality, we can assure you that there is no difference. Our jewellery pieces go through stringent quality checks and are accompanied by a lifetime warranty against defects.
