What applied diamond does

Applied Diamond, Inc. is a privately held specialty industrial materials company founded in 1986 and headquartered in Wilmington, Delaware. The company designs and fabricates chemical vapor deposition (CVD) diamond materials, components, and tools for use in aerospace and defense, high-power electronics, lasers and optics, and materials/physics research. Its core technology is microwave plasma CVD diamond synthesis, with capital equipment acquired from ASTeX in 1999 forming the backbone of its production capability.

The company operates a direct B2B sales model with custom quote-based pricing for engineered components and unit pricing for repair services. Its customer base spans the Americas, Europe, and Asia, and the company has been awarded multiple Small Business Innovation Research (SBIR) grants from the U.S. Department of Energy, indicating ongoing government-funded R&D activity. A sub-brand, DDK (Diamond Distributing Company), markets diamond knives, cleavers, and microscopy consumables, extending the company into life-sciences and materials-preparation tooling. Victor Tabeling serves as President and Owner.
