The invention discloses artificial stone comprising the following raw materials in percentage by weight: 50-60% of silicon dioxide, 25-35% of aluminum oxide, 6-10% of potassium oxide, 0.2-0.4% of calcium oxide, 0-0.5% of magnesium oxide, 0.03-0.05% of ferric oxide, 2-5% of novel crystal nucleus materials and graphene accounting for 1-3% of the weight of the silicon dioxide. A preparation process of the artificial stone comprises the following steps of weighing all components according to the ratio; mixing, namely uniformly mixing all the components in a stirring tank at the frequency of 800-1000r/min for 10-25 minutes; and carrying out compression molding, sintering and cooling to obtain the artificial stone, wherein the sintering temperature ranges from 1100 DEG C to 1300 DEG C, and the compression molding pressure is at least 500MPa. Due to the addition of the components in the ratio and the novel crystal nucleus materials in the artificial stone disclosed by the invention, the strength and wear resistance of the artificial stone are effectively improved; and the artificial stone has slight light transparency and is easy to machine and low in production cost.
