According to the molecular composition of jadeite, raw materials were prepared and calcined at a high temperature of 1350–1550 °C, then quenched to room temperature to obtain a glass with a jadeite composition. Crystallization was carried out at 1450 °C under a pressure of 5.00 Pa, resulting in the synthesis of gem-quality jadeite with dimensions up to approximately 12 mm × 6 mm. Differential thermal analysis and high-pressure thermal analysis were used to study the melting point variation of jadeite under both ambient and high-pressure conditions. The thermal stability of synthetic jadeite gemstones was further investigated through quenching, annealing, and aging experiments. The results show that the thermal stability of the synthetic jadeite gemstones is comparable to that of natural jadeite.
