水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

A basic thought in crystal buildings would be the device mobile. It's the smallest device of quantity that permits similar cells to get stacked collectively to fill all House. By repeating the pattern in the unit mobile time and again in all Instructions, the whole crystal lattice could be made. A dice is The best example of a device mobile. Two other illustrations are proven in Figure one. The initial would be the device cell for your facial area-centred cubic lattice, and the 2nd is for your body-centred cubic lattice. These structures are spelled out in the next paragraphs.
Big crystals of diamond are important gemstones. The crystal has other interesting Homes; it's the best audio velocity of any reliable and is the best conductor of warmth. Moreover diamond, the opposite prevalent sort of carbon is graphite, which is a layered material. Every single carbon atom has three coplanar close to neighbours, forming an arrangement called the honeycomb lattice. A few-dimensional graphite crystals are acquired by stacking comparable layers.

, has precisely the same framework, but There's two alternatives for selecting the holes the atoms will occupy. The third layer can be positioned in excess of the atoms of more info the 1st layer, creating an alternate layer sequence A
30Three times went earlier, and I was shocked to find out it once again: the many openings were being sewed up by slender and white thread and they looked such as ice crystal on Wintertime's branches within the north.
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
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。
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。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
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。
