A reliable is crystalline if it's got lengthy-vary buy. As soon as the positions of the atom and its neighbours are recognised at just one stage, the put of each atom is thought exactly throughout the crystal. Most liquids absence extensive-assortment buy, Even though several have quick-range purchase. Small array is outlined as the main- or next-nearest neighbours of an atom. In many liquids the initial-neighbour atoms are arranged in a similar framework as inside the corresponding reliable phase.
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。
晶及其石英岩类玉石是中低档宝玉石,虽比不上钻石、红蓝宝石的高贵,但在加工中如果构思巧妙而且加工精细,同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
Fig. seven: A template-directed method can Handle the placement of creating blocks over a surface area while in the here formation of elaborate structures.
C2 [ U ] transparent glass of extremely good quality, normally with its surface cut into delicate patterns:
⑧、雕刻:立体感强,工艺高,做工精细,成本高。分手工雕刻图形、机器雕刻文字。
Include to term list Add to term listing [ C/U ] transparent rock that appears like ice, or even a piece of it
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。
The definition of the solid appears evident; a stable is mostly regarded as getting hard and business. Upon inspection, however, the definition gets significantly less straightforward. A cube of butter, by way of example, is difficult after staying stored in the refrigerator and is Obviously a stable. Just after remaining about the kitchen area counter for daily, a similar cube results in being very soft, and it can be unclear If your butter should still be considered a good.
被主体水晶所捕获的包裹体。原生包裹体通常为固相,形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等,也会见到岩石碎屑或集合体。
Orthorhombic: They're rhombic prisms and dipyramids that resemble tetragons but without square cross-sections.
在透明的水晶中,隐裂纹呈亮晶晶的片状,有时还会有晕彩效应。这些裂纹是水晶在生长过程中,遇到外力挤压而在内部产生的一些隐形裂纹,隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充,形成愈合的裂纹,也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
