In the category of synthetic and treated stones, 'synthetic jadeite' is not commonly found in the market because the complex structure and formation conditions of jadeite make its synthesis extremely difficult, with costs far exceeding natural jadeite. Therefore, what is often referred to as 'synthetic jadeite' in the market usually pertains to optimized and treated natural jadeite (such as B-grade, C-grade) or imitations made of glass, plastic, etc. However, if true 'synthetic jadeite' theoretically existed, its fundamental difference from natural jadeite would lie in its formation process. Natural jadeite is an aggregate of silicate minerals formed deep within the earth's crust under high temperature and pressure over millions of years of geological activity, possessing a unique interwoven fibrous structure. 'Synthetic jadeite,' on the other hand, would be crystallized in a laboratory under artificially controlled conditions through chemical or physical methods, resulting in significant differences in its internal structure, mineral composition, and trace element content compared to natural jadeite. Preliminary distinguishing methods include: First, observing the luster—natural jadeite typically exhibits a vitreous luster, while imitations may show a resinous or waxy luster. Second, tactile sensation—natural jadeite has a higher density, feeling heavy in the hand, and is cool to the touch; imitations may feel lighter or warmer. Third, observing the internal structure with a magnifying glass—natural jadeite shows an interwoven fibrous or granular structure, while glass imitations may reveal bubbles or swirl patterns, and plastic imitations may show flow structures. Finally, without damaging the item, tapping it and listening to the sound—natural jadeite produces a crisp, pleasant sound, while imitations yield a duller sound. These methods are for preliminary assessment only; accurate identification requires professional instruments and appraisal institutions.
