水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

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。

Crystalline construction is characterized by a geometrical, repeating pattern of symmetric molecular framework. The arrangement of atoms kinds these purchased, repeating styles.

The weather are discovered in a number of crystal packing preparations. The commonest lattice constructions for metals are People attained by stacking the atomic spheres into quite possibly the most compact arrangement.
Crystals are often seen as a thing of huge elegance, plus they are commonly applied with diamonds or other stones to generate parts of jewelry. Nearly all crystals now are man-made in laboratories.

The basic units of solids are either atoms or atoms which have blended into molecules. The electrons of the atom move in orbits that type a shell framework within the nucleus. The shells are crammed in a systematic purchase, with Each individual shell accommodating only a little quantity of electrons. Distinctive atoms have distinctive quantities of electrons, that happen to be dispersed in the attribute Digital construction of filled and partly loaded shells.
The sodium chloride crystal lattice is characterized because of the close packing on the beneficial sodium ions and adverse chloride ions. Every single sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions, developing a extremely secure and symmetrical framework.
crystal, any reliable substance during which the component atoms are organized within a definite sample and whose floor regularity displays its interior symmetry.
