看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。

景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
Tetragonal: These crystals kind prisms and double pyramids. The structure is sort of a cubic crystal, other than one axis is more time than another.
C2 [ U ] clear glass of incredibly top quality, generally with its surface Slice into sensitive designs:
They are going to sooner or later produce a great tiny uniform cluster of atoms, this is the whole process of rising crystals. The more they will arrive with each other, the greater of a development will likely be visible into the bare eye. Scientists can ascertain what mineral They're thinking about by how the crystals variety.
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：
Crystals are absolutely nothing greater than an purchased arrangement of molecules or atoms. Crystals are available numerous shapes and sizes, and every one has distinctive features. The things they are created of determines how it'll type.
Among the binary crystals, the best buildings to visualise are These with equivalent numbers of the two kinds of atoms. The framework of sodium chloride relies on a dice. To assemble the lattice, the sodium and chlorine atoms are placed on alternate corners of the cube, along with the structure is recurring (Figure 3B).
[ C/U ] transparent glass of top of the range, typically check here with its area Minimize into patterns that mirror mild
Through the Cambridge English Corpus We are saying the chain topology within the significant w location functions as the proverbial ' scratch-on-theglass ' essential during the natural chemistry laboratory to produce crystals. From your Cambridge English Corpus Frequent-strain and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus As well as these, dust particles happen to be noticed in small-temperature plasmas, like These used in plasma processing and plasma crystals. From your Cambridge English Corpus The final Section of the e-book concentrates on peculiarities of strongly coupled dusty plasmas, like the formation of dust crystals and linked beautiful forces. Through the Cambridge English Corpus Comprehensive characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Major morphologies were not noticed. With the Cambridge English Corpus See all samples of crystal These examples are from corpora and from sources on the internet. Any views from the examples never stand for the feeling with the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
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
水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。
