A strong is crystalline if it's got extended-assortment order. When the positions of the atom and its neighbours are acknowledged at one particular place, the position of each and every atom is thought specifically through the entire crystal. Most liquids absence lengthy-assortment get, Whilst a lot of have quick-range order. Brief array is described as the 1st- or 2nd-nearest neighbours of an atom. In many liquids the very first-neighbour atoms are organized in a similar framework as within the corresponding sound phase.

一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
