⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
Chemical Bonds The categories of chemical bonds formed concerning atoms or groups of atoms in crystals count on their sizing and electronegativity. You can find 4 groups of crystals as grouped by their bonding:
Tetragonal: These crystals kind prisms and double pyramids. The structure is like a cubic crystal, apart from one axis is lengthier than one other.
. These four structures comprise a lot of the binary crystals with equivalent quantities of cations and anions.
Lattices can have 1 lattice issue for each cell or multiple, yielding a complete of 14 Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array produced by a set of discrete factors.
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
16I opened the box and saw a bit of crystal snowflake as well as a greeting card with click here "Pleased Birthday" during the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
crystal, any stable content during which the element atoms are organized in the definite sample and whose area regularity displays its inside symmetry.
21You all know the way once you have a crystal prism and pass a beam of daylight as a result of it, you will get a spectrum, which seems like a constant band of rainbow colors.
