Buy jade gems to learn these identification methods
Gold has a priceless jade, and experts from the city's gemstone industry association say that jade can be divided into jade and stone. Jade can be divided into two types: nephrite and jadeite, and jadeite is also known as jade. In the market, jade generally has three types: A, B, and C. A goods are natural jade, B goods are processed, and C goods are dyed.
(1) Water identification method. Put a drop of water on the jade. If it is in the form of dewdrops, it will be true jade for a long time.
(2) Hand touch method. If it is true jade, feel cold and lubricated by hand.
(3) Observation method. The jade is observed against the bright spot, and the color is clear and the green is evenly distributed.
(4) The tip of the tongue is identified. The tip of the tongue is really jealous, but the fake jade is not. According to reports, the common fake jade is generally made of plastic and glass. For example, the plastic can be picked with a steel needle, or it can be scratched and held in the hand. The glass shows bubbles inside the light or sunlight, and the raw materials make swirling stripes.
Identification of jade
Jadeite is a natural ore with extremely high hardness and very low yield. Its color is mainly green and red. The red is green and the green is green, hence the name jade. Quality identification of jade:
(1) Texture. The natural jade texture is transparent or translucent, and the surface is oily and lustrous. Careful observation reveals a slightly rounded, slightly transparent "salt grain" and fibrous material surrounding it.
(2) Hardness. Natural jadeite is jadeite, sculpted with sharp knives, leaving no traces.
(3) Green nature. The natural jade looks at the strong light, and it can be seen that there are other green mineral glitters, called green flowers or green.
(4) Relative density (specific gravity). The natural jade structure is hard and compact, has no bubbles, and has a high density. The sound is crisp when struck.
(5) Color. The authentic green color is pure and pure.
Identification of agate
The most obvious sign that natural agate is different from fake agate is that its cross section has a concentric layered structure. With this mark, the whole piece of agate is easier to identify, and the finished product after cutting is easy because there is no neat and obvious pattern. Admit mistakes.
In general, the natural agate feels cool, the surface is coated with a layer of wax, and has a waxy luster, translucent, with a small knife can not be carved; the surface is very fine after grinding, rubbing on a hard board for a dozen times, agate does not Hot, the board is hot; the color is often mixed in a piece, forming beautiful patterns, layers, brocade and other colorful patterns.
In addition to synthetic synthesis, the fake agate is made of high-quality stone. The basic characteristics are: the hand feels cool, but there is no waxy feeling and luster, opaque, and the lines between the colors are distinct.
