Member of the Antwerp diamond exchange
We enhanced the color of natural diamonds There is nothing artificial added and the color is permanent.

Henri Keesje, a diamond trader and member of the Diamond Exchange of Antwerp Belgium. I am the fifth generation of my family Keesje already in the diamond sector; started in Amsterdam in the Netherlands. As a trader, my objective is to offer a wide range of superior quality diamonds in all shapes imaginable. Besides the typical conventional diamond trading in which our company excels in, we also supply non conventional shaped diamonds, enh

anced colored diamonds, and exquisite custom made jewelry designs with invisible settings which are an answer to the increasing demands of today's market. Our fancy color enhancement process replaces heat and time below the earth with an accelerated electron beam to replace some of the carbon atoms, rearranging the crystal structure. The process does not use radiation so also no residual radioactivity and it complies with all European federal regulations. Please do not hesitate to contact me for any information. see:
