In partnership with Jochen Leën, Interpropsekt Group has established a vast network in the gem industry, allowing for a cohesive in-house process from the source to the market. This allows the company to ensure a socially responsible and sustainable origin of each individual stone, straight from the source. Along with a bespoke selection of high quality and rare gemstones, Interprospekt offers a wide repertoire of unique and precious stones.
