Distinguish between agate and crystal, the difference between agate and crystal

1 The top grade of agate is imported from Brazil, China's agate is mainly produced in the Northeast, its quality is not as good as Brazil's, because the agate bracelet handicrafts are very cheap, so the market is generally not fake.

2 Crystal bracelets are generally synthetic crystals or glass products.

3 Because the texture of agate and crystal is harder than glass, it will leave scratches on the glass and the bracelet is intact. The two single objects of agate (crystal) are gently rubbed against each other, and the smooth one is true, and the astringent one is not real.

Jadeite is pure, uniform, rich emerald green and delicate in texture, warm and transparent. Premium jadeite, the value can be comparable to emerald. Green but slightly transparent or translucent emerald veined jadeite is commercial grade, and there is a kind of green and light gray opaque that is called ordinary grade.

Buying jadeite A-grade products in regular shopping malls are given appraisal certificates and quality inspection certificates. Grade B products generally do not have an appraisal certificate.

Agate: There are many origins in China, and the natural color is called natural color, and red agate has dark red and bright red. Blue agate has a sapphire blue color, and there is a phenomenon of winding silk with different shades.

Green agate, water urchin agate, etc., these agates are rare in nature. The agate pattern is required to be clear, and the finer the band, the more precious. The products sold in the market are generally heat-treated, chemically dyed and irradiated, and they can change the color of the agate differently to make it more vivid and eye-catching.

You can read books on gemstones.

1. Crystal is a colorless and transparent large quartz crystal mineral. Its main chemical component is silica, which is a substance that "comes out of the same womb" as ordinary sand.

2. When the silica crystalline is perfect, it is crystal; After silica gelatinization and dehydration, it is the primary crystal mine, and the golden crystal variety is Nao; The aqueous colloids of silica become opal when solidified; When the silica grains are less than a few microns, chalcedony, flint, and secondary quartzite are formed.

3. Jade is divided into nephrite and jadeite, nephrite generally refers to white jade, green jade, jasper and Northeast Xiuyu produced in Xinjiang, China, and jadeite refers to jadeite produced in Myanmar. Whether it is nephrite or jadeite, their texture is very hard and the color is very bright, so they are known as the "king of stones".

4. Agate is also known as agate, agate, horse brain, etc., which is a kind of chalcedony minerals, often mixed with opal and cryptocrystalline quartz, with hardness, specific gravity, and color quite layered. There are translucent or opaque.

The difference between agate and crystal lies in the composition, color center, and formation process, the main component of crystal is silica quartz crystal, the common color center is yellow, purple, pink, which needs to be formed by the movement of the earth's crust in the natural environment, agate belongs to polycrystalline aggregates, with red, yellow, green and other colors being the most common, and the formation time is long and complex.

1. The composition is different crystals.

The main component of the crystal is silica, which is mostly colorless and transparent crystals, but when it is integrated into trace elements such as AI and Fe, it will appear purple, pink, brown, yellow, etc., agate is a polycrystalline aggregate, which is composed of countless tiny silica crystals.

2. The color center is different from agate.

Crystals are irradiated with trace elements to form different types of color centers, resulting in a variety of colors, such as purple, yellow, pink, etc., agate has a variety of colors, taking chalcedony as an example, there are usually red, green, yellow, brown, white and other colors, and there is a great difference with crystal.

3. The formation process is different crystals.

Natural crystals need to be produced in the natural environment, exist in the depths of the earth's crust, usually need to go through volcanoes and ** and other violent crustal movements to form, very rare, the history of agate is very long, the underground magma in the crust erupts in large quantities, the lava cools down and forms bubbles with other gases, and the later Piye period is cooled into the silica component, and finally forms agate.

1. The composition is different crystals.

The main component of the crystal is silicon dioxide, which is mostly colorless and transparent crystal, but when it is integrated into trace elements such as AI and FE, it will appear purple, pink, brown, yellow, etc., and the agate belongs to the multi-auspicious crystal aggregate, which is composed of countless tiny silicon crystals of the dioxide car.

2. The color center is different from agate.

Crystal irradiated trace elements to form different types of color centers, resulting in a variety of colors, such as purple, yellow, pink, etc., agate colors are diverse, taking chalcedony as an example, there are usually red, green, yellow, brown, white and other colors, and crystal is very different.

3. The formation process is different crystals.

Natural crystals need to be produced in the natural environment, existing in the depths of the earth's crust, usually need to go through volcanoes and ** and other violent crustal movements to form, very rare, the history of agate is very long, underground magma in the crust a large number of eruptions, lava cooled and other gases to form bubbles, later cooled into silica components, and finally formed agate.

Although the chemical composition of crystal and agate is silica, crystal is a quartz crystal, and agate is a polycrystalline aggregate. The color of the crystal is generally lighter, while the color of the agate is natural and pure, the internal texture of the crystal is cotton-like, and the inside of the agate has a layered circular striped ring.

1. Crystal agate.

Both crystal and agate are chemically composed of silica, but crystal is a quartz crystal, and agate is a polycrystalline aggregate. Crystal is composed of a crystal as a whole, and agate is composed of countless small silica crystals, the crystal crystal is based on agate, and there is generally agate in the ore with crystal.

2. Color crystal.

The color of crystals is generally lighter and transparent, while the color of agate is naturally pure and translucent. The color of crystal is light yellow, light black, maroon, pink, etc., while the color of agate is red, black, green, blue and other colors, the color of crystal is translucent and bright, and the color of agate is a gradient of laughing mountain.

3.Internal structure agate.

The inside of the crystal has a cotton wool-like texture, and it is irregular, and there are a small number of cracks in the large crystal, if the crystal is made a cut, the fracture is greasy and shiny. The texture inside the agate is naturally regular, and there are no impurities, no sand cores, no cracks, and the inside has layered circular striped rings of different colors.
