About our diamond experts


Worldwide Diamond Group’s highly qualified diamond experts are passionate about helping individuals and investors locate exquisite jewels that will increase in value. We have deep knowledge of the diamond industry and understand how natural fancy colored diamonds are valued, allowing us to deliver some of the finest investment-quality diamonds in the world to our clients.

Through our world-wide network, we will help you with each step of the process of sourcing your perfect natural color diamonds from sight holders, manufacturers, and private estates at unparalleled value. We can also arrange to showcase your diamonds in one-of-a-kind handcrafted pieces of jewelry.

Strategically investing in rare natural fancy colored diamonds have and continue to offer solid returns. The best strategy is to obtain colored diamonds today at our most competitive prices and hold onto them for a minimum period of three to five years. Due to the closure of Australia’s Argyle Mine in 2020, which was the world’s biggest supplier of natural fancy colored diamonds, astute investors have a distinct advantage in a time of high demand and very little supply.
