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。
A different fun, and delicious, experiment would be to variety huge crystals employing sugar. By heating sugar with drinking water after which letting this Alternative evaporate on sticks, you can form rock sweet from sugar crystals!
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。
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
. These 4 structures comprise many of the binary crystals with equivalent figures of cations and anions.
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

Within the Cambridge English Corpus We say the chain topology inside the substantial w area functions as being the proverbial ' scratch-on-theglass ' wanted within the natural chemistry laboratory to produce crystals. In the Cambridge English Corpus Consistent-tension and temperature molecular-dynamics simulations of crystals of the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. In the Cambridge English Corpus In combination with these, dust here particles have already been observed in small-temperature plasmas, like All those used in plasma processing and plasma crystals. From the Cambridge English Corpus The final Component of the reserve concentrates on peculiarities of strongly coupled dusty plasmas, like the formation of dust crystals and connected appealing forces.

The arrangement of an atom’s electrons decides its chemical Houses. The properties of solids usually are predictable with the Houses in their constituent atoms and molecules, and different shell structures of atoms are for that reason responsible for the diversity of solids.
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
