Hexa is a supplier of fine Colombian emeralds, with involvement at each stage of the supply chain. We provide the very finest investment-grade emeralds to high-end jewellers, wholesalers and collectors. The business has a truly international presence with our head office located in London and our manufacturing office in the heart of Bogota’s emerald district, ensuring the constant supply of extra fine quality emeralds for the international market at competitive prices.
We place great importance in working to stringent buying/manufacturing guidelines and export fine stones that meet the quality standards and expectations of our clients. Each Emerald is recorded and certified by up to two, sometimes three laboratories, CDTEC in Colombia and then in Switzerland by the SSEF or Gubelin to verify the provenance, quality and treatment of the stone.
