How to distinguish between natural crystals and synthetic crystals?

1. 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 jewelry is mostly smelted with residual canopy slag and glass slag, which is polished and colored, and there are no uniform stripes and catkins.

2. 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. If it is fake, there is no cool sense.

3. Natural crystal is a product of nature, in addition to the top chain of natural crystal transparent and flawless, bright and clean, the general natural crystal will have the existence of natural imprints such as cotton wool and ice cracks, and the artificial crystal is crystal clear, completely free of impurities, which is also the best distinguishing characteristics of natural crystal and artificial crystal.

4. In natural crystals, there are often inclusions and cotton, while synthetic crystals are crystal clear, and some have bubbles or solid impurities. Recently, some synthetic crystals often have some triangular long tubular pores in these pores, and there are green or red powders in these pores. This kind of long tube is characterized by a parallel arrangement in one direction, the section is triangular, and there are often uneven green or red powders distributed along the wall, the middle is often empty, and the end of the long tube has a tendency to become sharp.

And the real natural crystal is the crystal containing actinolite, rutile and other minerals, each of which has its own crystal form. They are encased in crystals, arranged at will without direction, with varying thicknesses, lengths, and lengths, and are often accompanied by inclusions and cotton inherent in natural crystals.

5. Synthetic crystals, especially colored synthetic crystals, are characterized by absolute uniformity of color. Natural crystal, on the other hand, cannot be uniform in color in every part, and it is born with color difference. This is especially evident in citrine, whose yellow color is actually a single piece of color radiating to the whole crystal, rather than the whole piece being yellow.

1. The chemical composition of artificial crystal and natural crystal is silica, and high-purity silica is called "crystal". Natural crystal is a kind of transparent quartz crystal, hexagonal columnar crystal, it is very hard, reflective (commonly known as colorful light) is extremely strong.

2. Pure crystals are colorless transparent crystals, and natural crystals without impurities can hardly be found, most natural crystals contain bubbles, impurities, and crystal corrosion.

3. Artificial crystal is made of raw quartz sand after a series of processes, and then made by fine cutting technology and flawless polishing, the crystal is pure and transparent, making up for the shortcomings of natural crystal.

4. The addition of artificial crystals to metal elements such as lead can enhance the dispersal of light and show the nobility of crystal. Due to the complicated process and superb craftsmanship of artificial crystal, some prices are even more expensive than natural crystal.

5. Artificial crystal is high-lead glass, or lead-crystalline glass, that is, adding 24% lead oxide to ordinary glass (composition is silica) will give artificial crystal similar to natural crystal in brightness and transparency.

(1) Look: natural crystal in the formation process, often affected by the environment always contains some impurities, when observing the sun, you can see a faint uniform fine horizontal stripe or catkins like substance. 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 hair strand: Put the crystal on a hair strand, and the human eye can see the double shadow of the hair through the crystal, it is a natural crystal, mainly because the crystal has birefringence.

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.

Identification of natural and synthetic crystals.

Another characteristic that distinguishes natural crystal from synthetic crystal is crystal luster, the surface of natural crystal jewelry shows grease luster, but the synthetic crystal jewelry table presents glass luster, and there is no synthetic crystal with Shantou luster.

Crystal, although not a precious gemstone, is increasingly popular among men, women and children all over the world for its unparalleled medical effects and low price.

The effect is not the same!

How is it made? Recycled crystals currently produced in Japan are artificially cultivated using a method known as the hydrothermal method. The basic principle is the same as that of natural crystals, which is in one or two.

A large amount of "anhydrous silicic acid" is injected into the three-storey sturdy blast furnace cylinder, silicon ditrophic acid is added, the bottom part is heated to about degrees Celsius, and the upper layer is kept at about degrees Celsius. The crystal nucleus is a bit like a transparent ruler of about a centimeter, and the crystal is attached to both sides of the crystal nucleus to crystallize, and the original "ruler" is caught by the regenerated crystal bag.

Natural crystal and crystal have the same constituent elements, the same growth direction, hardness, specific gravity, refractive index, and even birefringence, so can it replace natural crystal? From the perspective of electronic parts, it is indeed much cheaper than natural crystals, easier to obtain, more stable in quality, and standardized in size, so it has indeed replaced natural crystals.

Why don't you buy Yangjing? If you are pursuing crystals to be healthy and wealthy, or to ward off evil spirits, good luck, and adjust feng shui, of course, raising crystals does not have this effect! Natural crystal has been bred in nature for tens of millions of years, even hundreds of millions of years, and everyone believes that it has its magnetic field, which helps to improve the qi of the human body, so people are so reluctant to raise crystals!

However, it costs thousands of yuan to buy Yangjing in a department store, which is really unreasonable! In any case, the crystal is less than the natural crystal from the spirituality of nature, think about it, the chicken and the feed chicken are not the same, why some doctors will still recommend that it is better to eat the chicken tonic? Crystals are the same, but in a different form of supplementation!

Generally, natural amethyst bracelets range from tens of yuan to about two hundred yuan.

Synthetic crystals don't have any effect, because synthetic crystals are more beautiful than crystal roughs, so many of them are synthetic!

Of course it's different, synthetic crystals don't have any effect, and it's not good to wear them for a long time.

The two are completely different, and the efficacy is completely different, crystal is a natural substance formed naturally in an instant under high temperature and high pressure, but synthetic crystal is an artificially made glass material; I wish you happiness.
