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。

⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。

A crystal construction concentrates on how the atoms are organized Within the crystal. However, crystallographers have an interest in the overall form and dimensions in the crystal in addition to its external qualities. To accomplish this, they should know about the crystal procedure.

③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。

《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”

⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。

时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：

如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。

Many crystals behave like butter in that they're challenging at low temperatures but comfortable at larger temperatures. They may be termed solids in any way temperatures below their melting point. A feasible definition of the sound is undoubtedly an item that retains its shape if remaining undisturbed. The pertinent concern is just how long the article retains its condition. A extremely viscous fluid retains its form for one hour but not a yr. A stable should hold its condition lengthier than that.

The definition of the good seems evident; a stable is usually regarded as remaining difficult and company. On inspection, on the other hand, the definition turns into significantly less easy. A cube of butter, such as, is difficult soon after being stored in a fridge and is particularly here Plainly a strong. Following remaining to the kitchen counter for a day, a similar dice results in being quite gentle, and it's unclear In case the butter need to nevertheless be considered a sound.

The basic models of solids are either atoms or atoms that have combined into molecules. The electrons of an atom transfer in orbits that variety a shell composition across the nucleus. The shells are filled in a systematic purchase, with Each individual shell accommodating only a small variety of electrons. Unique atoms have various numbers of electrons, which can be dispersed in the characteristic electronic structure of loaded and partially crammed shells.

There are other minerals and molecules that can variety these crystal lattices. Snowflakes absolutely are a basic example of a around symmetric and geometrically patterned composition from ice crystals, and gemstones of all types are typically crystals.

crystal, any reliable content through which the element atoms are organized in the definite sample and whose area regularity displays its internal symmetry.

This crystal structure is liable for the distinctive Actual physical and chemical Qualities of sodium chloride, like its significant melting place, electrical conductivity, and ability to type ionic bonds very easily.
