These crystals ended up formed above one million decades in the past In the Earth's crust. They take place if the liquid within the Earth consolidates and also the temperature chills. Other crystals variety when the liquid would make its way from the clefts and dispense minerals to the clefts.
12He tried using yet again in numerous other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。
Encyclopaedia Britannica's editors oversee topic areas where they've got in depth understanding, regardless of whether from many years of expertise received by working on that material or via review for an advanced degree. They produce new content and confirm and edit written content obtained from contributors.
You will discover a number of crystals depending on geometric constructions, crystal expansion, and product. There might be preparations of hexagonal carbon atoms or amethyst that makes hexagonal pyramid buildings.
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
Ionic Crystals: Electrostatic forces variety ionic bonds. A vintage case in point is usually a halite or salt crystal.
Among the binary crystals, the simplest constructions to visualize are These with equivalent figures of The 2 forms of atoms. The framework of sodium chloride is based on the dice. To build the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, plus the composition is repeated (Figure 3B).
Crystals with noticeable flat faces are identified as euhedral crystals, although All those lacking outlined faces are referred to as anhedral crystals. Crystals consisting of ordered arrays of atoms that are not usually periodic are known as more info quasicrystals.

Crystals are not simply renowned for their Bodily visual appearance, but different crystals of different elements and formations can result in an enormous selection of employs and physical Houses.
crystal, any solid materials in which the element atoms are arranged inside of a definite pattern and whose area regularity demonstrates its internal symmetry.
This crystal structure is answerable for the unique physical and chemical properties of sodium chloride, like its higher melting stage, electrical conductivity, and talent to kind ionic bonds quickly.
