A crystal construction focuses on how the atoms are arranged Within the crystal. Nonetheless, crystallographers have an interest in the general condition and sizing from the crystal in addition to its external features. To accomplish this, they need to understand about the crystal process.

看原料:选料精良的水晶制品,应看不到胶口及棉絮;质地纯净、光润、晶莹为好。
