How much is the price of natural crystal?

Natural crystal is formed under natural conditions and grows in the depths of the earth's crust. It usually goes through violent crustal movements such as volcanoes and earthquakes. It belongs to mineral resources and is one of the very rare and precious gemstones. The value mainly lies in the functional effect of its ore magnetic field on the human body. Let's take a look at the price of natural crystals.

How much is the price of natural crystal?

Ordinary natural crystal market price is not very high, usually as long as a hundred yuan did not buy, such as white crystal, powder crystal, tea crystal, amethyst, topaz can be done as long as a hundred yuan, top white crystal beads and ordinary flowers below 10 mm price of no more than 20 yuan / string, more than 12 mm not more than 30 yuan 40 yuan / string. Of course, the price of the best crystal, green ghost and hair crystal is very expensive, the quality of more than a thousand, or even tens of thousands.

The selection and purchase method of Natural Crystal

1, look at the raw materials: well-selected crystal products should not see the glue mouth and cotton, the texture is pure, smooth, crystal is better.

2. Look at the workmanship: the processing process of crystal products is divided into grinders and sculptors, such as crystal necklaces, bracelets, earrings, etc. belong to abrasive products, audio images, internal painting snuff bottles, etc.

3, look at polishing: the quality of polishing directly affects the value of crystal products, which is divided into soft polishing and hard polishing.

4. Look at the hole: for crystal products (such as necklaces, bracelets, Buddha beads), it depends on whether the hole is straight, whether the thickness of the hole is uniform, and whether there are small cracks, the hole wall must be clear and transparent without "white marks".

5, look at the color: in the same kind of crystal, different parts of the texture, color also have their own advantages, belong to monochromatic uniform chromaticity, in the same crystal depth requires its tone lines beautiful and generous.

6. look at culture: if the pictograph of the inclusions in the crystal can be related to culture, religion and history, the price is often several or even hundreds of times higher than the value of the crystal itself.

Identification of true and false natural crystals

1, look at: natural crystal in the formation process, often affected by the environment always contains some impurities, looking at the sun, you can see a touch of uniform fine horizontal grain or willow floc-like substance. And false crystal mostly use residual crystal slag, glass slag smelting, after polishing processing, coloring imitation, there are no uniform stripes, willow floc-like material.

2, tongue licking: natural crystal even in hot summer dog days, with the tongue licking natural crystal surface also has a cold and cool feeling, there is a faint fragrance, fake crystal does not have a cool feeling.

3. Lighting: natural crystals stand upright in the sun, giving off beautiful luster no matter which angle they look at, while fake crystals cannot.

4. Hardness: the natural crystal is hard. If you gently scratch the ornaments with gravel, it will not leave a trace. If you leave a mark, it is a fake crystal.

5. Polarizer: turning 360 degrees under the polarizer, the natural crystal has four bright and four dark changes, and the false crystal has not changed.

6. Dichroism: natural amethyst has dichroism, false crystal has no dichroism.

7. Magnifying glass: check under the transmitted light with a ten-fold magnifying glass, and those who can find bubbles can basically be defined as false crystals.

8. Hair: put the crystal ball on a hair, and if the human eye can see the double shadow of the hair through the crystal, it is the crystal ball, mainly because the crystal has birefringence, but it is impossible to distinguish between natural crystal, nourishing crystal and melting crystal, but can only distinguish other substances such as glass.

9. Thermal conductivity meter: adjust the thermal conductivity meter to green 4 grid to test gemstones, natural crystal can rise to yellow 2 grid, while false crystal does not rise, when the area is large, it will rise to yellow grid.
