⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。

The C60 molecules, also known as buckyballs, are very solid and Virtually incompressible. Crystals are formed this sort of that the balls are organized in an fcc lattice having a one particular-nanometre spacing between the centres of adjacent balls. The similar C70 molecule has the shape of a rugby ball; C70 molecules also form an fcc crystal when stacked with each other. The sound fullerenes type molecular crystals, with weak binding—supplied by van der Waals interactions—amongst the molecules.
