Artificial gemology is a science that involves the use of various techniques to artificially enhance the color, transparency, luster, and durability of natural gemstones to increase their decorative effects and economic value. Gemstone improvement includes the enhancement of color, transparency, luster, density, and the enhancement of physical and chemical stability, as well as optical identification and material determination. The study and application of artificial gemology are of great importance to the jewelry industry and gemstone identification fields, as it not only increases the aesthetic value of gemstones but also promotes gemstone scientific research and industrial applications.
