轴性、光性：一轴晶正光性。正交偏光下所看到的一轴晶干涉图是独特的，其黑十字臂未达中心，形成中空的图案，俗称牛眼干涉图。中心部分通常为淡绿色或淡粉色。
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。
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。
If you would like see how crystals are shaped, you are able to perform a little task with your really very own kitchen area and find out the development of the crystals occur together with your personal eyes . This may be completed by Placing a little number of table salt into some normal faucet drinking water, hold out 24 hours, and you may see wonderful cubed formations. This occurs since the water is evaporating, which brings about the atoms that make up the salt (the mineral) plus the drinking water to come back nearer jointly.
You can also find lots of supplies that resemble crystals but are literally polycrystals. Polycrystals sort when microscopic crystals fuse together to variety a reliable. These components tend not to consist of requested lattices.
Learn the way The form on the crystals determine different minerals into familiesMinerals crystallize In keeping with amongst 7 motifs, often called crystal units.
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：
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
24I intend to make my which means crystal distinct.我想把我的意思解释得清清楚楚。《牛津词典》
[ C/U ] transparent glass of top of the range, generally with its floor cut into designs that reflect mild
Solitary crystals of metals are soft and malleable, although polycrystalline metals are more difficult and more robust and tend to be more valuable industrially. Most polycrystalline here resources may be built into significant solitary crystals after extended warmth treatment method. Up to now blacksmiths would warmth a bit of metal to make it malleable: heat will make a couple of grains develop large by incorporating scaled-down ones. The smiths would bend the softened metallic into shape and after that pound it awhile; the pounding would enable it to be polycrystalline once again, growing its toughness.
You'll find only some various device-cell designs, so a number of crystals share a single device-mobile kind. An essential attribute of a unit mobile is the amount of atoms it has. The entire amount of atoms in your complete crystal may be the number in Each and every mobile multiplied by the volume of device cells. Copper and aluminum (Al) Just about every have one atom for every unit cell, whilst zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per unit mobile, but there are numerous exceptions. Crystals of polymers, such as, have A huge number of atoms in Every device mobile.
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
