I specialize in restoring, refashioning, and reselling vintage and modern diamonds - maximizing the inherent value of all styles.
If you wish to beautify your own heirloom diamond - or sell it, trade it or make a unique new purchase - you deserve a master cutter's expertise. Please contact me.
The Diamond Wizard™ is your resource for expert information about the fine art of cutting diamonds - please be sure to review all my videos and posts below.
All cutting is done in my workshop.
My signature cut, the American Rose Brilliant, combines two traditional styles to outperform standard rounds - the artistry of a classic rose cut crown with the precision of a highly reflective modern pavilion.
Because rough diamonds are not readily available to individual artisan cutters, my primary source of raw material is old-fashioned cut diamonds that entered the American market in the pre-WWII era.
Sourced, designed, and cut exclusively in the USA.
My name is Maarten de Witte aka The Diamond Wizard™.
I have 50 years' experience as a master diamond cutter in the United States. Formerly the Director of the American School of Diamond Cutting, I'm also a craftsman, innovator and teacher of diamond design, branding, and sales.
I view the world of diamonds through a work-hardened lens. My scope spans from the solitary workbench to the global industry, with primary focus on promoting excellence in the American diamond trade.
