How to see the authenticity of fluorite, is fluorite valuable?

The main imitations of stone and identification methods:

The banding characteristics of fluorite are similar to those of agate, but its luster and hardness are much lower than those of agate, and the bands are wider and the boundaries are blurred, and there is no sharp angular transformation. Fluorite purple or with a good strip pattern, the appearance is more beautiful, often made gemstone necklaces, carvings, etc., others are only made of beads.

1. Look at miscellaneous belts:Good fluorite.

The characteristics of miscellaneous bands with agate stones.

similar, but its smoothness, compressive strength.

It is much lower than that of agate, and the miscellaneous zone is wide and the boundary is blurred, and it is not easy to have the characteristics of oblique angular transformation. If the boundary is clear, it is not a good fluorite.

2. Look at the texture:Good fluorite is purple or has a very good miscellaneous texture, the appearance is better, often made into gemstone necklaces, carvings, etc., and some others are only made as beads.

3. Look at the color:Fluorite is often counterfeited as multicolor tourmaline.

The multi-color of tourmaline is generally green-red, green-yellow, green-white, while the multi-color of fluorite is mostly green-purple, pink-purple, etc. However, there is no purple in tourmaline, so it is also an effective way to distinguish the real and fake fluorite and tourmaline, as well as the good and bad.

Fluorite maintenance precautions.

It should be noted that the hardness of green fluorite is low, so the maintenance of fluorite bracelets is very important, and when wearing, pay attention to avoid wear and tear between each other, bumps and bumps will also cause surface damage, and it is best to clean and put it in the jewelry box when not wearing.

The biggest feature of green fluorite is fluorescence, which is also the main reason why fluorite is loved by everyone. However, the fluorescence of fluorite is conditional, and the purple color of fluorite will fade under the irradiation of strong light, and gradually turn into light green, which is an irreversible chemical process, so special attention should be paid to preventing the irradiation of strong light when maintaining and collecting fluorite.

The main chemical component of fluorite blocks is calcium fluoride, and the output is very large. Like tourmaline, fluorite is very colorful. As a result, fluorite is often made into tourmaline knock-offs to deceive consumers.

Fluorite blocks are often pretended to be bicolor tourmalines. In fact, it is not very difficult to distinguish between the two.

1. Hardness: The hardness of tourmaline is at Mohs scale, while the hardness of fluorite is only about 4 degrees on the Mohs scale. In contrast, tourmaline is not scratched by steel at all, while fluorite can be scratched by glass.

2. Luster: Because the hardness is much lower than tourmaline, the luster of fluorite is far inferior to tourmaline.

3. Color: Fluorite is often pretended to be two-color tourmaline. The bicolor of tourmaline is generally red and green, red and yellow, green and white, while the bicolor of fluorite is mostly green-purple, pink purple, etc. But there is no purple in tourmaline, so this is also an effective way to distinguish the real from the fake fluorite and tourmaline!

4. Characteristics of tourmaline such as dichroism, birefringence index, and thermoelectric. A common halide mineral, it is a chemical compound, its composition is calcium fluoride, which is an important mineral for the extraction of fluorine. Fluorite comes in many colors and can also be transparent and colorless.

Transparent and colorless fluorite can be used to make special optical lenses.

The banding characteristics of true fluorite are similar to those of agate.

However, its luster and hardness are much lower than that of agate, and the bands are wide and the borders are blurred, and there are no sharp and angular transformations. If the boundary is clear, it is a fake fluorite. Fluorite is named because it fluoresces under ultraviolet and cathode rays.

Fake fluorite does not fluoresce when exposed to sunlight. In fact, it is bicolor tourmaline that is often used to pass off as fluorite.

The bicolor of tourmaline is generally red and green, red and yellow, green and white, while the bicolor of fluorite is mostly green-purple, pink purple, etc. However, there is no purple in tourmaline, so this is also an effective way to distinguish the real and fake fluorite and tourmaline, as well as the good and bad. In addition, the hardness of fluorite is only about 4 degrees on the Mohs scale, which can be scratched by glass.

The hardness of tourmaline is in the Mohs scale, in comparison, tourmaline will not be scratched by glass.

Pay attention to the following points to identify fluorite:

1. Fluorite can emit light, but it is very, very little. The fluorite that can emit light on the market is basically soaked in iridium water.

2. In fact, a lot of fluorite will be post-processed and then sold, as long as you pay attention when you buy it, it will not die, that is, it will not look dead, natural things are active, and the processed ones will be very stiff, and it will obviously feel lifeless.

Fluorite is calcium fluoride, CaF2, which is the optical material with the smallest dispersion and the most expensive in optical glass. Common colors: green, blue, brown, yellow, pink, purple, colorless, etc.

Hello, fluorite is not the same according to the fineness.

** Not the same.

I don't know if the fluorite you're referring to is a rough stone ** or a finished product.

Here's an example. Now the general city of fluorite bracelets.

The first-hand market purchase ** is in the range of tens of yuan.

Of course, the good quality is higher.

Fluorite, fluorite, also known as fluorite, is a mineral whose main component is calcium fluoride (CaF2).

It contains more impurities, Ca is often replaced by rare earth elements such as Y and CE, and also contains a small amount of Fe2O3Chinese name: Fluorite English name:

Definition of fluorite: a halide mineral with the chemical formula CaF2, which belongs to the equiaxed crystal system. It is a mineral raw material for extracting fluorine and preparing fluoride.

SiO2 and trace amounts of Cl, O3, He, etc. Fluorite in nature often shows bright colors and has a lower hardness than a knife. It can be used in the preparation of hydrogen fluoride:CaF2

2hf↑;Before the technology of artificial fluorite was mature, it was one of the materials used in the manufacture of optical glass for lenses. Abbreviation: FL

Chinese name: fluorite[1] Chinese alias: fluorite; calcium fluoride; fluorspar powder; fluorite powder; Calcium fluoride, fluorite ore is worth 1kg

Fluorite is not very valuable, good quality is valuable.

Fluorite is also known as fluorite.

One of the more common minerals in nature, which can coexist with other minerals, is produced in many places in the world, and has 5 effective varieties. Equiaxed crystal system, the main component is calcium fluoride.

CAF) crystallizes into octahedra and cubes.

The crystal is vitreous, bright and changeable in color, brittle in quality, and the Mohs scale.

It is 4, the melting point is 1360, and it has the property of complete cleavage. Some samples can emit light when exposed to friction, heat, ultraviolet light, etc.

Key Value: Fluorite is the only one that can be refined in large quantities of fluorine.

Mineral. It is also used as a co-solvent in steelmaking to remove impurities. The mineral is used in the production of glass and enamel.

There are also camera lenses made of fluorite because of their very low dispersion.

As a result, the lenses made from them have less chromatic aberration than lenses made of ordinary glass.

Fluorite is rich in color and crystal smooth, and is known as "the most vivid gemstone in the world". However, due to its low hardness, it is usually not used as jewelry. However, because of the soft texture of fluorite, it is relatively easy to use it to carve ornaments when large enough crystals appear.

The mineral is very popular among ore collectors. In particular, some specimens in good condition can appear very high**.

Fluorite. The key points of quality identification (distinguish between good and bad):

Fluorite is a low-grade gemstone because of its low hardness as a collectible, ornament, or processed into a ball necklace. Its composition is calcium fluoride.

The main characteristic of fluorite is the cube.

But it is often lumpy, with many stripes, and the common colors are purple, green, yellow, orange, colorless, etc., transparent to translucent, with weak luster, due to low hardness, the surface is easy to wear, and can be carved with a knife.

1.Zoom in to inspect the gaps.

2.Hot needles test fusible resins and plastics.

3.Ultraviolet fluorescence observation shows that filled plastics and resins can have characteristic fluorescence.

Irradiation treatment: Colorless fluorite can produce purple color by irradiation. Irradiated fluorite is extremely unstable and will fade when exposed to light, so this treatment method is not practical.

Identification of the authenticity of the night pearl.

Natural night pearl is extremely rare and rare, we identify its authenticity, in addition to the scientific identification of gems and jade, but also according to the many characteristics it has.

It is a light gray fluorite that can shine continuously for tens of hours after 15 minutes of light.

It has a phosphorescence phenomenon, that is, it can produce the quasi-effect of the night pearl.

The natural night pearl is beautiful in color, translucent, and does not need any light, that is, it permanently emits active light, and the luminous energy is larger. The artificial night pearl is filled with luminescent powder in the fissures of fluorite that does not shine by itself, and only partially or line-like glows, and the time is short and fleeting.

It is necessary to distinguish the fluorescent light from phosphorescence, the phosphorescent phenomenon is the effect of the external light source, and it can maintain a certain luminescence time after being removed.

Observe the luminescence length, uniformity, half-life, and afterglow length.

The quality of fluorite is mainly based on the content of CaF2, at the beginning it is necessary to take a part of the ore sample for testing, and then compare it with the ore specimen according to the test results.
