第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。

Solitary crystals of metals are soft and malleable, whilst polycrystalline metals are tougher and stronger and tend to be more practical industrially. Most polycrystalline materials is usually created into huge solitary crystals soon after extended warmth treatment. Prior to now blacksmiths would warmth a piece of metallic to make it malleable: warmth helps make a number of grains expand big by incorporating smaller sized kinds. The smiths would bend the softened metal into condition and afterwards pound it awhile; the pounding would ensure it is polycrystalline again, rising its strength.
