Natural crystal is the product of nature, in the earth's crust after tens of millions and even millions of years of refining, has condensed and formed and spread out a unique energy.Artificial crystal, also known as artificial piezoelectric crystal, high lead glass, because of its lead, should not be worn for a long time.Artificial crystal is a laboratory or workshop product, the formation time is short, variety is single, the inclusion body is monotonous, can not be compared with nature myriad.The following are several common artificial crystal and natural crystal identification methods.
First, natural crystal and synthetic crystal naked eye difference:
1. Synthetic crystal has uniform color or parallel color bands.Synthetic crystals have an even, dull color that usually gives a gaudy impression.Natural crystals have uneven color distribution and often carry naturally formed marks such as sponges and ice cracks.
2 Synthetic crystals have seed crystal characteristics.Before processing, the synthetic crystal has a flat sheet seed crystal plate in the center of the crystal, and the crystal development will have the corresponding characteristics.Natural crystals do not.
3 Synthetic crystal crystals are pure and flawless.Synthetic crystals are usually pure and flawless, and some have round bubbles and syrup-like structures. Solid inclusions are often fine breadcrumbs, which are undissolved raw materials.Natural crystal can be seen a wide variety of various forms of inclusion, cotton, ice crack, inclusion mainly rutile, tourmaline and other natural minerals as well as liquid water.
Two, natural crystal and melting crystal naked eye difference:
Smelting crystal is also called quartz glass, crystal or glass ballast as raw material, heating to melt the crystal, cooling is melting crystal, and natural crystal in the appearance is very similar.
1. The hardness.Natural crystals have a Mohs hardness of 7, and natural white crystals can be carved into ordinary glass.The hardness of melted crystal is less than that of natural crystal, and when carved with ordinary glass, it will leave an impression.
2. Inclusion shape.The inclusion form of natural crystals is rich and natural.The inclusion of melted crystal is usually white cloud, if the color chemical agent is added during melting, it will cause the inclusion color to be all a certain color, such as red, etc.
3 Touch and feel.Natural crystal has a cold feeling, melting crystal cold feeling is not obvious or warm feeling.Holding natural crystal will feel cold into the heart, wear - later and body temperature synchronization, melting crystal has a warm feeling.
Three, the difference between natural crystal and color crystal:
Changing color crystal, is on the basis of natural crystal, through certain methods, change the color of natural crystal or its inclusion, in order to achieve the purpose of beautification.In jewelry, some color modification methods are recognized and defined as "optimization", which can be regarded as natural products, such as agate, etc.;And in the collection circle or pay attention to crystal spirituality, it is not recognized color crystal.The reason is that crystal in the process of being changed color, inevitably will be hurt, resulting in the loss of energy.In addition, because the color is changed artificially, it may be used incorrectly.
To distinguish between natural crystal and modified crystal, you need to have a gradual understanding of the endless fake means, and continue to pay attention to and accumulate market experience.If there is no relevant experience, then generally use the intuitive method, that is, when you feel wrong and unhappy, don't buy.
