对这类水晶晶簇观赏石的欣赏与评价，主要是强调晶体的完整、品种的名贵（如紫水晶、烟晶、发晶等）、造型奇特、含有名贵晶体（如辰砂、辉锑矿等）伴生等。晶簇产于矿床晶洞中，长相完美的并不多见，要完整无损地采集下来，又比较困难，故而采集起来代价较大，精品晶簇价值也就昂贵了。

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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
Crystalline framework is characterized by a geometric, repeating pattern of symmetric molecular structure. The arrangement of atoms forms these requested, repeating styles.
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。
Crystals glance distinctive from a number of other rocks and minerals, but �?barring a number of Particular cases �?nearly all minerals disguise a crystalline structure underneath the surface area.
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。
Q.four. Exactly what is the distinction between atomic framework and crystal composition? Ans. The principal difference between atomic framework and crystal structure lies inside their definitions: atomic framework refers to how atoms are organized inside of a single molecule or simply a cluster of molecules, whereas crystal structure issues the precise arrangement of atoms inside a stable material.
晶体 Silicon crystals grown inside of a laboratory change light into electrical Strength. 在实验室中长成的硅晶体可将光线转变为电能。
One crystals of metals are tender and website malleable, though polycrystalline metals are more durable and stronger and tend to be more handy industrially. Most polycrystalline elements is usually designed into huge single crystals immediately after extended heat therapy. Previously blacksmiths would warmth a bit of metal to really make it malleable: warmth will make several grains mature huge by incorporating lesser types. The smiths would bend the softened metallic into shape and after that pound it awhile; the pounding would make it polycrystalline once again, increasing its power.
There are actually other minerals and molecules that can form these crystal lattices. Snowflakes certainly are a typical example of a approximately symmetric and geometrically patterned structure from ice crystals, and gemstones of all versions are usually crystals.
