摘要： The invention relates to a single crystal CVD diamond material, wherein the extended defect density as characterized by X-ray topography is less than 400/cm2 over an area of greater than 0.014 cm2. The invention further relates to a method for producing a CVD single crystal diamond material according to any preceding claim comprising the step of selecting a substrate on which to grow the CVD single crystal diamond, wherein the substrate has at least one of a density of extended defects as characterized by X-ray topography of less than 400/cm2 over an area greater than 0.014 cm2; an optical isotropy of less than 1×10-5 over a volume greater than 0.1 mm3; and a FWHM X-ray rocking curve width for the (004) reflection of less than 20 arc seconds.

摘要： An invisible information mark is provided on a facet of a diamond gemstone by applying a plasma resist to the exposed surface of the gemstone, applying an electrically conducting layer of metal to the region where the information mark is to be formed, ablating a selected zone of the metal and resist layers by ultraviolet laser thus forming a mask on the surface of the facet, electrically connecting the metal layer and plasma etching the facet through the mask, thus forming a mark of appropriate depth on the surface of the gemstone.
