看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
The essential units of solids are either atoms or atoms that have combined into molecules. The electrons of an atom go in orbits that form a shell click here construction throughout the nucleus. The shells are crammed in a systematic order, with Every shell accommodating only a little amount of electrons. Different atoms have diverse numbers of electrons, which happen to be distributed in a very attribute electronic construction of filled and partially loaded shells.
Crystal Lattices There are seven units of crystal constructions, that happen to be also known as lattices or Place lattices:
