Romper el diamante

De InfoDiamond:

The mechanical resistance impact is, in general, the opposite to the hardness of the stone. In other words, a stone of high hardness is more fragile to shocks. A diamond will be thus relatively fragile to shocks. Diamond has also a very strong elasticity which makes it rebound as a ball when it strikes a hard surface. A shock which could be insufficient to break a gem can cause dammages if applied repetively. A rock crystal hitting a diamond could often have less dammage than the diamond itself. The heat treatments used to improve the color of the gems weaken them by modifying their internal structure. A gem having a plan of perfect cleavage will be able to break easily according to this direction after the shock of a blade. For example, for diamond, we use this method to separate two pieces of rough diamonds, this operation is called: cleavage.

Los diamantes son de los materiales mas resistentes de la tierra, solo pueden ser rotos con otro diamante o con un láser potente.
