I specialize in restoring, refashioning and reselling antique, 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 and touch. Please contact me.
All cutting is done in my workshop.
My signature cut is the American Rose Brilliant. It combines two traditional styles - the artistry of a classic rose cut crown, and the precision of a highly reflective modern pavilion - outperforming standard rounds.
Rough diamonds are not readily available to artisan cutters. For this reason, "estate" diamonds are my basic raw material. These Old Mine and European Cut diamonds entered the American marketplace in the pre-WWII era.
Sourced, designed, and cut exclusively in the USA.
My name is Maarten de Witte, aka the Diamond Wizard. With 45 years experience as a master diamond cutter in the USA, I am former Director of the American School of Diamond Cutting. I'm a craftsman, innovator and teacher of - cutting, design, branding, sales, research and development.
I view the world of diamonds through a work-hardened lens. My scope spans from the solitary workbench to the global industry, with a primary focus on preserving excellence in the American diamond trade.
