John Le Parc – Gemmologist & buyer

John was born in the South of France, from Colombian parents. John’s parents instilled in him the cultural values of Colombia and cultivated his interest in the rare emerald gemstone, which is found in the heart of Colombia and worshipped by the indigenous peoples. John became passionate about emeralds when he was 10, during a trip in Colombia when he saw for the first time the gemstone in the hands of a dealer. From that moment on he decided that his life would gravitate around gems. He decided to study International Business in France and then moved to London to follow a course at the Gem-A Gemmological Institute to become a gemmologist, whilst at the same time working in the jewellery and gemstone industry.

Orlando Cifuentes – Gem grader – Colombia

Orlando is a Colombian with a passion for emeralds. Based in Bogotá, Orlando has over 30 years’ experience grading, cutting, polishing and exporting the finest Colombian emeralds. In a market that is highly opaque and notoriously difficult to navigate, specialists with decades of practice and technical knowledge of the first degree are essential to buying the right stones at the right price. Orlando can instinctively sort a highly valuable emerald from one that is a fraction of its quality in seconds, a skill that enables the best loose stones to be selected for onward distribution and export. Once Orlando has directed the cream of the ‘crop,’ these stones are then sent for laboratory testing to provide indisputable black and white evidence of their provenance and true market value.
