Through continued innovation and ambition to be a leader in the industry the company has kept its place at the top of the market place. To ensure continued guaranteed value to clients Monnickendam decided relinquish being a sightholder in 2003, having been one since 1929. This move provided Monnickendam the greater flexibility to source rough diamonds from a larger range of mines. Greater choice enables Monnickendam to always purchase at competitive prices and select according to the personal requirements of our clients'.

It is worth remembering that for all polished diamonds supplied by Monnickendam, the rough has been sourced in strict adherence to the Kimberly Process. Thereby, adding to the reassurance our clients receive, in purchasing diamonds of excellent quality and value, they have been sourced with impeccable ethics.
