How to choose natural crystal, which is better, natural crystal stone or crystal

However, the most important thing is to like it, and the methods to identify the authenticity of the crystal when purchasing are roughly as follows:

1) Eye: In the process of formation, natural crystal is often affected by the environment and always contains some impurities, and when observing the sun, you can see a faint uniform fine horizontal stripe or catkins. The fake crystal is mostly smelted with residual crystal slag and glass slag, polished and colored, and there are no uniform stripes and catkins.

2) Tongue licking: Even on dog days in the hot summer, licking the surface of the natural crystal with your tongue gives you a cold and cool feeling. Fake crystals, there is no cooling feeling.

3) Illumination: Natural crystal is placed vertically in the sun, no matter which angle you look at, it can emit a beautiful brilliance. Fake crystals cannot.

4) Hardness: Natural crystal has high hardness, and it will not leave traces if you gently scratch it on the jewelry with crushed stone; If there are streaks, it is a fake crystal.

5) Check with a polarizer: Rotate 360 degrees under the polarizer and have four bright and four dark changes are natural crystals, and those that do not change are fake crystals.

6) Check with dichroism: natural amethyst has dichroism, and false crystal has no dichroism.

7) Check with a magnifying glass: Check with a ten-fold magnifying glass under transmitted light, and the bubbles that can be found can basically be determined as false crystals.

8) Check with a strand of hair: Limited to a perfectly round crystal ball. If a crystal ball is placed on a strand of hair, and the human eye can see the double shadow of the hair through the crystal, it is a crystal ball.

Mainly because crystals are birefringent. However, this cannot distinguish between natural crystal crystals, cultivated crystals and smelted crystals. Only other substances such as glass can be distinguished.

9) Detection with thermal conductivity meter: adjust the thermal conductivity meter to 4 grids of green to test gemstones, natural crystals can rise to 2 grids of yellow, while false crystals do not rise, when the area is large, it rises to one grid of yellow.

You go to Baoding and buy it, I can guarantee that it is true. Shijiazhuang is not familiar. Intercity trains, it's very convenient.

Summary. Dear It must be said that natural crystal is good, natural crystal is a product of nature, and the general natural crystal stone will have the existence of natural imprints such as cotton wool and ice cracks; The artificial crystal is crystal clear and completely free of impurities, which is also the best distinguishing feature of natural crystal and artificial crystal.

Natural crystal is a kind of gemstone that has undergone a long period of geological activities in nature to be formed, because the process is uncontrollable, so there are generally small defects such as cotton wool and ice cracks in the crystal, which is also one of the important characteristics of natural crystal; While the crystal grows, the crystal will continue to absorb the pure energy of nature, so the natural crystal has the magnetic field and energy that the synthetic crystal does not have, which is one of the most unique charms of the natural crystal.

Crystals are spiritual things, and different crystals have different spirituality. However, people often think that natural crystal stones, because they took millions of years to form (much longer than the history of human beings), will contain the aura of heaven and earth, and the spirituality is stronger. The artificial crystal stone is made of post-processing, so the spirituality is much weaker than the natural crystal stone.

The biggest difference between natural crystal and artificial crystal is the color. Because even if it is made like artificial crystal, there are still some aspects that do not meet the standards of natural crystal. For example, the color distribution of natural purple crystal is uneven, irregular flake distribution, and there are gas-liquid inclusions; Synthetic purple crystals are uniform in color and have a daughter crystal nucleus in the center.

In general, the color of natural crystals is unevenly distributed, while the color of artificial crystals is monolithic and unnatural.

Second, there are some flocculent textures in the natural crystal, and the distribution is very uniform, while the artificial crystal does not have these fine textures. Observing against the sun, no matter how high-end the natural crystal jewelry is, you can see the faint and uniform fine horizontal stripes or catkins texture, while the fake crystal jewelry can not see the uniform stripes and catkins texture against the sun.

Difference 3: The applicable occasions of natural crystal and artificial crystal are very different, and the natural crystal stone that reaches the gem level is a very good jewelry, which can be made into all kinds of jewelry, crystal bracelets, crystal pendants and crystal rings; Artificial crystal is different, because it contains lead, it cannot be worn for a long time, and can only be used in electronic processes, optical instruments, etc. Of course, if you buy artificial crystal jewelry, you can only wear it for a short time and through clothing.

Crystals are not all natural, and according to their different types, they are divided into natural and acquired man-made. The formation time of natural crystal is generally relatively long, and it is relatively rare, which is a very precious mineral resource. Synthetic crystals and molten crystals, on the other hand, are artificially made, and their production processes are different.

Some crystals are natural crystals, which are divided into natural crystals, synthetic crystals and molten crystals according to different types, some of which are artificially made and some are naturally formed. Natural crystal is formed under natural conditions, belongs to pure natural minerals, has not been carved, generally grows in the depths of the earth's crust, after complex crustal movement and tempering, is a very rare mineral resources.

Synthetic crystals, also commonly known as recycled crystals, are a single crystal that is artificially created after birth. Regenerated crystals are crystals formed after 1 to 3 months by imitating the growth process of natural crystals, placing pure natural ores and some chemicals in an autoclave to imitate the complex movement of the earth's crust.

Molten crystals are often mistakenly referred to as synthetic crystals, but they are not of the same type and are made differently. The raw material of molten crystal is crystal waste, which is synthesized by reaction at high temperature and high pressure. It is characterized by being very resistant to high temperatures, and can be used to make crystal cups, baking trays, and tea sets, and is very durable.

There are generally two types of natural crystals: crystals and particulate crystals, the shape of crystals is generally hexagonal, and there are many small particles inside the microcrystals, and the shape of the crystals is irregular. The crystals include white crystal, citrine, and amethyst. Particle crystals include hair crystals, rainbow crystals, and rose crystals.

Classified crystals of natural crystals.

Natural crystals are divided into two categories: knotted hollow crystals and microparticle crystals, and the shape of crystals is generally hexagonal, and it is in the shape of crystal pillars. There are many small particles inside the microparticle crystal, the shape is irregular, and the surface of the crystal is very smooth, and there is hydrated silica between the crystals.

Crystals. The types in the crystal body are white crystal, citrine, amethyst, brown citrine, ink crystal, most of these crystals are relatively transparent, and the internal structure is complete, among which amethyst also contains trivalent iron and manganese, ink crystal contains organic matter, citrine contains divalent iron.

Particulate crystals.

The types of microcrystals include hair crystals, rainbow crystals, rose crystals, and smoky crystals, and the structure of these crystals is composed of small crystals. Rainbow crystals contain small bubbles and cracks, and the light is repeatedly refracted in the cracks to form a rainbow color, while smoky quartz is smoky yellow, and the crystals also contain diamond components.

According to the differences in color, morphology and physical properties:

1. White crystal: colorless, transparent crystal like water.

2. Amethyst: purple transparent or translucent (containing ferric iron and manganese) 3. Smoky trine (commonly known as citrine), a smoky yellow or smoky brown transparent crystal.

4. Ink crystal: inky black, containing translucent crystals of organic matter.

5. Citrine: yellow to red-orange-brown transparent crystal (containing divalent iron) 6. Rose crystal (also known as "hibiscus stone"): rose-colored, light rose-colored to dense lumps (containing trace elements such as TI).

7. Hair crystals: those containing hair-like mineral inclusions such as diamond and hornblende.

8. Rainbow crystal: A crystal containing fine bubbles or quenching to fill cracks, which produce a rainbow by interfering light.
