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。

23Sometimes, however, the crystal form of the silicate inclusions is observed to resemble much more closely The interior construction of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。

天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。

Substantial crystals of diamond are valuable gemstones. The crystal has other interesting Homes; it has the very best audio velocity of any stable and is the best conductor of heat. Other than diamond, the opposite typical method of carbon is graphite, which happens to be a layered material. Each individual carbon atom has a few coplanar in close proximity to neighbours, forming an arrangement known as the honeycomb lattice. Three-dimensional graphite crystals are received by stacking comparable levels.

How Crystals Kind The entire process of forming a crystal is called crystallization. Crystallization normally happens any time a sound crystal grows from the liquid or Resolution.

Find out how The form with the crystals establish the various minerals into familiesMinerals crystallize Based on among 7 motifs, known as crystal programs.

水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。

Hexagonal �?Characterized by four axes, 3 of which are equivalent in length and intersect at a hundred and twenty degrees, that has a fourth axis perpendicular to the opposite a few.

24I want to make my meaning crystal apparent.我想把我的意思解释得清清楚楚。《牛津词典》

The definition of the reliable seems apparent; a solid is normally regarded check here as being hard and firm. Upon inspection, however, the definition gets fewer clear-cut. A cube of butter, such as, is hard following remaining saved inside a refrigerator and is also Plainly a solid. Soon after remaining around the kitchen counter for each day, the same cube results in being really gentle, and it's unclear if the butter should still be regarded a sound.

看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。

There are actually other minerals and molecules that will type these crystal lattices. Snowflakes undoubtedly are a typical example of a roughly symmetric and geometrically patterned framework from ice crystals, and gemstones of all versions are typically crystals.

The framework in the sodium atoms alone, or the chlorine atoms alone, is fcc and defines the device mobile. The sodium chloride construction thus is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is predicated on the bcc framework; each other atom is cesium or chlorine. In such cases, the device cell is actually a cube. The 3rd significant structure for AB

⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
