SPECIAL DIAMOND PRODUCTS
Diamond Anvil
Our high-performance diamond anvils allow scientists to simulate & recreate the extreme pressure conditions found deep inside planets and distant celestial bodies. Leveraging the unmatched strength, transparency, and heat resistance of diamond, these anvils can compress microscopic samples to a pressure of the order of 400 GPa (approx.)—more than four million times Earth’s atm. pressure. Designed for cutting-edge research, our diamond anvils enable breakthroughs in material discovery, planetary science, and fundamental physics. Renowned universities and research institutions worldwide trust our anvils for their exceptional precision, reliability, and optical clarity—making them the cornerstone of high-pressure studies and experimental research.

Design variants
We offer a wide selection of anvil designs, each optimized for your different experimental requirements:
Each anvil is custom-made with culet sizes from 500 µm to 10 µm, precision-cut in the (100) orientation, and polished to atomic smoothness for maximum performance.
Our commitment to scientific integrity is reflected in the way we validate every anvil we produce. Using advanced characterization techniques such as polarized light microscopy, FTIR spectroscopy, and Raman analysis, we ensure each diamond anvil meets the highest standards of purity, crystallinity, and stress-free operation. These quality checks guarantee that our products not only perform exceptionally under high-pressure conditions but also deliver consistent and reproducible results.
