What We Provide
Precision-Engineered Diamonds for High-Tech & Luxury Need
At Supreme Green, we specialize in advanced lab-grown diamond solutions—combining unmatched purity, cutting-edge engineering, and sustainable innovation. Whether you need ultra-pure quantum substrates, high-performance thermal management, optical-grade precision, or exquisite gem-quality diamonds, our products are designed to exceed industry standards.
Optical Grade
We synthesize ultra-pure, single-crystal diamond substrates with >80% broadband transparency (UV to IR) – delivering near-theoretical optical performance for systems where material limits define…
Quantum Grade Diamonds
At the heart of quantum technology lies an extraordinary material—diamond, enhanced by engineered atomic defects. Nitrogen-vacancy (NV) centres in diamond serve as ultra-sensitive quantum sensors…
Thermal Grade
Deploy the world’s highest thermal conductivity material (2000+ W/mK) in scalable formats – from precision single-crystal heat spreaders to 4-inch polycrystalline wafers – solving thermal bottlenecks in power electronics…
Electronic Grade
We pioneer electronic-grade diamond with atomically controlled doping (Boron/Phosphorus), buried heterostructures, and epitaxial integration – unlocking diamond’s…
Mechanical Applications
We deliver single-crystal diamond components with sub-micron tolerances, crystal-orientation control, and <5 nm surface roughness – engineered to outperform in cutting tools, nano-indentation, and...
Gem Quality
At Supreme Green, we craft flawless lab-grown diamonds that rival nature’s finest—offering D-F color, VVS+ clarity, and precision cutting for unmatched brilliance. Our ethically created, sustainable diamonds…
