Zusammenfassung:A synthetic crystal and a manufacture method thereof are provided to manufacture high-gloss black synthetic crystal as an accessory and the like by using pozzolan, which turns its color into black when fused. A method for manufacturing synthetic crystal comprises: a first mixing step of mixing 50-67wt% of raw material for crystal and 33-50wt% of pozzolan powder in 300mesh size; a second fusing step of fusing the mixed materials at the temperature of 1400-1500°C; a third molding step of putting the fused materials in a mold and molding the materials; a fourth cooling step of cooling the molded materials at the temperature of 500-550°C for certain time; and a fifth re-cooling step of re-cooling the cooled materials down to room temperature.
