London Diamond Bourse Launches Competition to Win Four Places in New Coloured Gemstone Course

The London Diamond Bourse is delighted to announce the launch of its new Coloured Gemstone Course, expanding its portfolio of professional education programmes for the jewellery industry. 

Building on the success of the Practical Diamond Knowledge Course and the Diamond Manufacturing Course, the new one-day course has been developed to give jewellery retailers, sales professionals and others working within the industry who want to build their practical knowledge and confidence when selling coloured gemstones. 

To celebrate the launch, the London Diamond Bourse is offering four complimentary places, each worth £300, on the inaugural course taking place on Monday 3 August 2026. 

Participants will gain practical, hands-on insight into coloured gemstones while learning from experienced industry professionals in the heart of Hatton Garden. The course is designed to help those working in sales speak about coloured gemstones with greater confidence, answer customer questions and develop the knowledge and skills to turn conversations into successful sales. Charlotte Rose, President of the London Diamond Bourse, said: “Coloured gemstones are as much an integral part of the London Diamond Bourse as diamonds. Education is at the heart of everything we do, so we’re delighted to expand our education programme with the introduction of our new Coloured Gemstone Course – a one-day course that gives professionals an introduction to the fascinating world of gemstones and the practical knowledge and confidence to sell them with expertise.
