The Hong Kong Diamond and Gemstones Laboratory EGL Asia has added a new service - the release of reports or certificates for laboratory-created diamonds of jewelry quality, according to a press release from the company.
Joseph Kuzi, General Director of the Laboratory, said that the interest and demand for laboratory stones in the Asian market is growing, which necessitates the appropriate certification of man-made gemstones, which are currently being sold in the retail and consumer markets of Asia.
The laboratory's services are currently used by both suppliers of laboratory diamonds and sellers of natural gemstones. For example, Chow Tai Fook uses EGL Asia reports to confirm the natural origin of all small diamonds used in its products.
"Naturally, reports on laboratory stones differ significantly from reports on natural diamonds," Kuzi said. Nevertheless, like natural diamonds, the laboratory evaluates laboratory stones according to the classical 4C system, taking into account such characteristics as size, proportions, symmetry, faceting and glow.
