What is a crystal? Is it true that what is sold on the street? How to recognize?

What is sold on the street is generally not real, and many are plexiglass.

1) See: 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 scratch it lightly with gravel; 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.

Crystals are silica. The easiest way is to add hydrochloric acid to dissolve.

Summary. Hello, dear, you can distinguish the authenticity of the crystal by the following methods: 1. Observe the appearance:

1. Look at the appearance of the crystal, the appearance of the real crystal is crystal clear, shiny, colorful, textured, and textured, while the appearance of the fake crystal is dull, no color, no texture, and no texture. 2. Look at the edge of the crystal, the real crystal edge is relatively smooth and there is no obvious notch, while the edge of the fake crystal is not smooth and has obvious notch. Second, observe the weight:

1. Real crystals weigh heavier, while fake crystals weigh less. 2. Real crystals weigh much heavier than fake crystals because real crystals contain more minerals, while fake crystals are made of plastic or other materials and weigh less.

2. Look at the edge of the crystal, the real crystal edge is relatively smooth and there is no obvious notch, while the edge of the fake crystal is not smooth and has obvious notch. 2. Observation weight: 1. The weight of the crystal of the true circle Wang Zheng is heavier, while the weight of the false crystal is lighter.

Hello dear, there is no way to judge through **, you can judge according to the method given by the teacher.

It has a lot of that kind of tiny cracks in it.

Hello, the small cracks in the crystal bucket are often called "cracks" or "internal cracks" by the demolition. These cracks can be due to the crystal's influence on pressure or temperature changes during the formation process. In addition, cracks in the crystal can also be formed due to damage or wear and tear on the crystal during transportation or processing.

While these cracks usually do not affect the aesthetics of the crystal, they may affect the strength and durability of the crystal.

I'm so afraid that it's glass, it's very smooth and transparent when it comes into water, and I didn't say that the small droplets of water got on it.

Hello, dear, crystal and glass can be distinguished by the following aspects:1Color:

The color of crystal is usually purer and more transparent than glass because it is made from natural minerals. 2.Refractive index:

Crystal has a higher refractive index than glass, so it produces a brighter sparkle effect in sunlight. 3.Weight:

Hydrotanite is heavier than glass of the same size. 4.Sound:

Striking the crystal and the glass will make different sounds. Crystals make a crisp sound, while glass makes a dull sound. 5.

Hardness: Crystal is harder than glass, making it more wear-resistant. It is important to note that some glass products may also be painted with color or specially treated to make them look like wide-eyed tung crystals, so it is best to judge them in a variety of ways.

Summary. Dear, hello, I am happy to serve you, through the official query shows, how to check that you buy real crystal: 1, look inside the crystal under the sun to observe, the real crystal will have evenly distributed fine horizontal stripes or catkins inside, and the fake crystal inside is mostly crystal slag and glass slag.

2. Test the temperature of natural crystals are cool and cool, and they will be much cooler than fake crystals, so you can put 2 crystals in your hands to feel it, and after touching, the crystal that feels cold is a real crystal. 3. Look at the refraction Put the crystal under the polarizer for observation, the real crystal will show light and dark changes, you can also put the hair under the crystal to observe, if you can see the double shadow of the hair through the crystal, it proves to be true. 4. Listen to the sound Gently tap the crystal with your fingers or other objects, the real crystal sound is crisp and has a metallic sound, while the fake crystal sound is very dull.

Dear, hello, I'm happy to serve you, through the official query of Hail, how to check that you bought a real crystal: 1, look at this inside Put the crystal in the sun for observation, the real crystal will have evenly distributed fine horizontal stripes or catkins inside, and the fake crystal inside is mostly crystal slag and Sen pin code glass slag. 2. Test the temperature of natural crystals are cool and cool, and they will be much cooler than fake crystals, so you can put 2 crystals in your hands to feel it, and after touching, the crystal that feels cold is a real crystal.

3. Look at the refraction Put the crystal under the polarizer for observation, the real crystal will show light and dark changes, you can also put the hair under the crystal to observe, if you can see the double shadow of the hair through the crystal, it proves to be true. 4. Listen to the sound Gently tap the crystal with your fingers or other objects, the real crystal sound is crisp and has a metallic sound, while the fake crystal sound is very dull.

1. Impurities are naturally formed, and will be affected by the environment during their growth, and their internal medium-sized sources will contain certain impurities. 2. Luster Most of the surface of real crystal shows a relatively rigid glass luster, no matter from which angle it is observed, it can show obvious shining brilliance, while fake crystal does not have these, the luster is relatively dull, and the surface is relatively dry. 3. Hardness The internal structure of real crystal is dense and hard, hard, the use of sharper items on the surface of a few strokes, generally will not leave traces on the surface, and most of the fake crystals are synthetic, the hardness is small, after the use of hard items crossed, will be rented on the surface to leave obvious traces.

Summary. Hello, crystal cheap is not fake, crystal to be divided into many kinds, there are low, low and high-end, amethyst white crystal is very cheap dozens of dollars can buy moonstone gram price compared to amethyst, white crystal is more expensive, mainly look at the body is not transparent, blue light is not strong, and then the big beads must be more expensive and good-looking, in general, moonstone cheap within 100 can also be bought, good quality thousands are also possible.

Is crystal cheap fake.

Hello, crystal cheap is not fake, crystal to be divided into many kinds, there are low, low and high-end, amethyst white crystal is very cheap dozens of dollars can buy moonstone gram price compared to amethyst, white crystal is more expensive, mainly look at the body is not transparent, blue light is not strong, and then the big beads must be more expensive and good-looking, in general, moonstone cheap within 100 can also be bought, good quality thousands are also possible.

You've done a great job! Can you elaborate on that?

The method of identifying the authenticity of the crystal can be distributed from the following three aspects: 1. Impurities, there are catkins in the inside of the real crystal, and the inside of the fake crystal is crystal clear; 2. Luster, the real crystal is glass luster, the luster of the fake crystal is dim, and the surface is relatively dry; 3. Hardness, use hard items to scratch, real crystals will not leave traces, fake crystals will leave obvious traces.
