Identifying crystal jewelry, now offers the following three big methods. There are a few small points in each big method for everyone to refer to and learn. For those who have first met crystal jewelry, it is very helpful. Please read the following carefully.

Mainly from the appearance to distinguish:

(1) Look at the selection of materials: crystal materials with excellent selection of materials should not see star-shaped, cloud-like and flocculent gas-liquid inclusions. The texture is pure, smooth and crystal-clear. If it is found that there are cracks and spots with different depths, it is a defective product.

(2) Look at the workmanship: The processing of crystal products is divided into two types, namely, the grinder and the engraver. Such as crystal necklaces, bracelets, earrings, etc. are abrasive products; Guanyin image, inner painting snuff bottle, etc. are engravings. A well-made crystal product should be exquisitely refined, not only can fully display the external beauty (styling, style, symmetry, etc.) of the crystal product, but also tap its inner beauty (smooth, clever color) as much as possible.

(3) Look at polishing: The quality of polishing directly affects the value of crystal products. The crystal must be honed by diamond sand during the processing, and the rough production will cause traces of friction on the crystal surface. Good crystal products have better natural transparency and luster, and they are said to be "fire heads".

(4) Look at the hole: For the crystal products (such as necklaces, bracelets, beads), it is necessary to see whether the holes are straight, whether the thickness of the holes is symmetrical, whether there are fine crack holes, the walls must be clear and transparent, and there is no “white mark”.

(5) Look at the color: Even in the same kind of crystal, the texture and color of its different parts have different styles. It is monochromatic, and if the chromaticity is uniform on the same crystal, it is required to have a beautiful color tone.

(6) Look at coordination: When buying crystal jewelry, you should try to wear it to see its size, tightness and length. If it is inlaid with ornaments, see if it is firm, Zhou Zheng and coordination. Also pay attention to whether the style and color of crystal jewelry are coordinated with your body, skin color, face and clothing.

The method of evaluating the value of crystals and identifying true and false:

(1) Quantity: The smaller the number, the better. There are many colorless crystals and smoke crystals, and there are fewer citrine and amethyst crystals.

(2) Clarity: The purer the crystal ball, jewelry, etc., the better. Ornamental crystals require inclusions.

(3) Envelope: complete, image, colorful, and clear meaning is the top grade.

(4) Process: The styling requires proportional coordination, the primary and secondary points are clear, the image is realistic, and the polishing requirements are bright and without scratches.

True and false crystal identification method:

(1) Seeing: In the process of forming natural crystals, it is often affected by the environment and always contains some impurities. When observing the sun, you can see the faint uniform small horizontal stripes or catkins. The fake crystals are often smelted with crystal slag and glass slag. After polishing and coloring, there is no uniform streaks or catkins.

(2) Tongue: Even in the hot summer days, using the tongue to rub the surface of the natural crystal, there is a cold and cool feeling. Fake crystals have no cool feeling.

(3) Illumination: The natural crystal is placed vertically under the sunlight, and it can give off beautiful brilliance from any angle. Fake crystals can't.

(4) Hardness: The hardness of the natural crystal is large. Use the gravel to gently stroke the ornament, leaving no traces; if there are streaks, it is a fake crystal.

(5) Check with a polarizer: 360 degrees under the polarizer is a natural crystal with four dark and four dark changes, and no change is a fake crystal.

(6) Check with two colors: natural amethyst has dichroism, and fake crystal has no dichroism.

(7) Check with a magnifying glass: Under the transmitted light with a ten-fold magnifying glass, the bubble can be found as a fake crystal.

(8) Check with hair silk: Put the crystal on a hair silk, the human eye can see the double shadow of the hair through the crystal, it is natural crystal, mainly because the crystal has birefringence.

(9) Detection by thermal conductivity meter: The thermal conductivity meter is adjusted to the green 4 grid test gems, the natural crystal can rise to the yellow 2 grid, and the fake crystal does not rise, and rises to a yellow grid when the area is large.

In short: Although there are many methods, many methods are actually relatively simple to distinguish. The more you understand the crystal, the more you understand it, the more you can grasp the meaning and connotation of the crystal. Naturally, it is not difficult to distinguish.
