                Home > About CVD Diamond

                The diameter of our CVD diamond wafer can measure up to 70mm,the thickness canbe 0.3mm – 2.5mm. The CVD diamond wafers also can be cut into different geometrical shapes, and according to the customers' requirment we can do the polish work to achieve mirror-like finishes on single side or double sides.

                The performance parameters of CVD diamond we manufacture being close to the natural diamond Ⅱa.
