Primary minerals in the Triassic Yaoshan Formation basaltic bismuth rock, sand is located in the Fangshan around the water system. Changle Sapphire variety of colors, rich variety, but most of the dark sapphire color, transparency is poor, through the optimization can improve its quality. Sapphire contains a variety of inclusions. Processing must be based on the theoretical value of kiosk angle, to ensure that does not reduce the grade of precious stones.
