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 view in videos and posts below.
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.
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.
My view of the diamond world comes through a work-hardened lens. Its scope spans from the solitary workbench to the global diamond industry, with primary focus on promoting excellence.
DIAMOND WIZARD® provides information related to diamond cutting.
