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。

杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。

发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。

Crystals are frequently viewed as anything of enormous attractiveness, and they are commonly utilized with diamonds or other stones to create parts of jewelry. The majority of crystals now are man-built in laboratories.

晶体 Silicon crystals grown inside of a laboratory change light into electrical Power. 在实验室中长成的硅晶体可将光线转变为电能。

Solitary crystals of metals are smooth and malleable, though polycrystalline metals are harder and stronger and tend to be more useful industrially. Crystal Most polycrystalline products is usually made into massive one crystals just after extended heat treatment. In past times blacksmiths would heat a bit of steel to make it malleable: warmth helps make a couple of grains improve massive by incorporating scaled-down types. The smiths would bend the softened steel into condition after which pound it awhile; the pounding would make it polycrystalline once again, raising its toughness.

Molecular Crystals: Overall molecules are bonded to each other in an organized way. A superb case in point is often a sugar crystal, which includes sucrose molecules.

crystal, any sound materials wherein the component atoms are arranged in the definite pattern and whose floor regularity displays its inside symmetry.
