A sapphire crystal growth method includes a first step of grinding, a second step of purification, a third step of spraying and drying particles, a fourth step of adding organic bonding agent, a fifth step of press molding, and a sixth step of crystal growth. Thus, the sapphire crystal growth method has a shorter crystal growth time than that of the conventional crystal growth method. In addition, the sapphire crystal growth method has a lower price, has crystals whose mass and size are unlimited, and has a higher quality.
