How do CVD diamonds compare to natural Diamond?
CVD diamonds have the same physical, chemical and optical properties as mined diamonds. The only difference between lab-grown and earth-mined diamonds is their origin. CVD diamonds are faceted and polished by the same highly skilled diamond cutters who facet and polish mined diamonds.
Natural diamonds show a wider range of properties. A sophisticated system for the categorization of natural diamond stones with respect to color, clarity, defects and so on has been established. High-quality polycrystalline CVD diamond does have similar properties like perfect natural stones.
