This concept applies equally in one, two, and a few-dimensional spaces. All the crystal lattice is usually produced by frequently reproducing the sample of your unit cell in all Instructions.

A fundamental notion in crystal buildings will be the unit cell. It is the smallest device of volume that allows identical cells to generally be stacked collectively to fill all Area. By repeating the pattern of your device cell again and again in all directions, the entire crystal lattice is often built. A dice is the simplest illustration of a device mobile. Two other examples are proven in Determine one. The primary would be the device cell for a face-centred cubic lattice, and the next is for your human body-centred cubic lattice. These buildings are spelled out in the following paragraphs.
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Fig. four: Constructing blocks with diverse designs and surface area chemistries direct the development of unique crystal symmetries.
Lattices may have just one click here lattice position for every cell or multiple, yielding a complete of fourteen Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array produced by a set of discrete details.

损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
Crystals with obvious flat faces are named euhedral crystals, whilst those missing described faces are called anhedral crystals. Crystals consisting of ordered arrays of atoms that are not constantly periodic are referred to as quasicrystals.
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。

⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
