Physical properties of gemstones called "quartz emerald", "quartz ruby" and "quartz sapphire" were examined. The properties were identical with those of quartz and it was concluded that they were dyed "crackled" quartz crystals. Measurements of transmission curves of gemstones and absorption spectra of dyes extracted from them were carried out. As the result, they showed remarkable differences in comparison with natural stones.
