How can you tell the difference between an ordinary stone and jade?

How to identify stones and jade? One step to distinguish the difference

In the traditional concept, it is believed that "the beauty of stone is jade", as long as it is a beautiful stone, it can be called jade, so it seems that jade is a stone, but in the current view, jade is definitely not an ordinary stone. But it is undeniable that ordinary stones and jade still confuse many people, so in today's article, I will talk to you about how to identify stones and jade, and let's go to the following to see how to identify stones and jade!

How to identify stones and jade, first of all, we must clearly know the conditions to become jade: beauty, durability and rarity are the indispensable conditions for becoming jade. Beauty means that the color should be bright and pure, with high transparency and high purity, and should have a certain glossy presentation effect.

Durability means that the jade should have a certain hardness, toughness and chemical stability, while scarcity means that the yield is small.

So how to identify stone and jade, the first step, the first step is to see whether the color is beautiful and shiny, the second step is to see whether its hardness is high, you can first scratch with your nails, the hardness of the nails is about 2 to about, if you can leave a mark with your nails, it is very likely that it is not jade, and then you can use a knife to scratch, the hardness of the knife is about 5. Most jade stones have a hardness of more than 5, so they can also leave marks with a knife, and it is very likely that it is not jade either. Therefore, looking at color and hardness is the easiest way to distinguish between stone and jade.

Of course, if you still can't determine whether it is stone or jade according to the above methods, you must send it to a professional testing agency for testing.

1. Drip method: drop water on the surface of the stone, if the water droplets are like drops on the lotus leaf and do not disperse, it means that this piece is jade, not an ordinary stone. Because jade has a certain degree of delicacy and oiliness.

2. Hardness: the hardness of the stone, the higher the hardness, the better the jade quality, generally as the minimum hardness of the jade, the rough standard is that the knife is scratched without marks. 3. Hand touching:

The rough jade will be very cold when it is first touched, and after touching it for a long time, the temperature of the jade will slowly rise to the temperature of the human body, and there will even be a warm feeling when rubbing it continuously. After the touch is stopped, the residual temperature will also be maintained for a while. 4. Observation method:

Although the appearance of the jade rough stone is different from that of the stone, its color is natural and clear, and it will be found that the whole piece of jade has light energy penetrating when it is exposed to the light (or under the illumination of a flashlight with higher brightness). If you use a magnifying glass**, some will have various cracks. To know the degree of interweaving of the internal structure of the stone, the denser the interweaving, the more uniform the jade quality, the better.

Extended information: Color: The white of white jade is often slightly bluish, and there are few extremely white and pure white, while the glass is a uniform white and pure white.

After the lamp shines, the glass still has a slight orange light. Jade: One of the jade properties is warm and greasy, like a paste like fat, and although the glass is also moist, it feels that the essence is exposed, and it feels like there is a thief light flashing in the moist.

Fracture: This is a distinct characteristic, the fracture of white jade is stony, dark ballast without light, jagged or jagged, while the fracture of glass is a material characteristic, bright ballast is light, shell-like. Although the jewelry appraisal cannot be used for destructive testing, it can be observed by some accidental bumps, unpolished surfaces, edges and corners, etc.

Specific gravity: The specific gravity of jade is in between, and the glass is on the left and right, compared to the glass is lighter. Sound:

It's really too easy to distinguish jade from ordinary stones, and I've learned another trick!

Judging whether a stone is jade can be distinguished according to four aspects: texture, color, specific gravity, and transparency, as follows:

1. The texture of jade is relatively hard, and it feels delicate, smooth and warm in the hand, with a sense of oil, reluctant to let go, and flashes with a soft gemstone luster. Because jade is relatively hard, it cannot be smashed easily. The stone is loose, the skin is rough, there is a feeling of grinding, it does not emit luster, and sometimes it will break when it falls on the ground.

2. Jade will show different colors, such as white, cyan, emerald, ink, blue, etc., sometimes several colors are mixed together, and its color is bright and shiny. The stones are mostly earth gray, there is no surprise, and some stones also have different colors, such as the colorful stones of Shandong, but the color is dim and does not exude luster.

3. The specific gravity of jade is relatively large, and it is heavier in the hand and has a feeling of pressure. The specific gravity of the stone is small, and it flutters lightly in the hand.

4. Jade is transparent, some are transparent, some are slightly transparent, and the beam has a sense of convergence. Ordinary stones do not have transparency, although some quartz stones and mineral crystals have transparency, but the beam is relatively scattered and unobstructed.

Characteristics of common jade:

1. Hetian jade: the color is mainly white, and many of them are yellow, green, blue, black and other colors because they contain different metal elements. The hardness is 6 0 6 5 on the Mohs scale. The jade is tender, delicate and warm, many are opaque, a few are translucent, and most of them are oily or wax-like luster.

2. Xiutian jade: the color is mainly green, and the impurities are white, yellow, red and other colors. The hardness is low, between Mohs 2 5 5 5, and the structure is compact. Most of them are translucent to opaque, and a few are transparent, generally with a glass or grease luster.

3. Nanyang jade: Nanyang jade contains a variety of alteration minerals, so it has a variety of colors, mostly yellow, white, variegated, and purple, blue, yellow and other colors. The hardness is 6 6 5, most of them are opaque or translucent, with a glass luster, and are known as Nanyang jadeite because of its good luster.

4. Lantian jade: the color is yellow with green, the color is unevenly distributed, and it is often cloud-like or spotted. The hardness is about 4 on the Mohs scale. Most are opaque and have a slightly vitreous or greasy sheen.

5. Jadeite: common green is the mainstay, as well as white, brown, red and other colors. The hardness is as high as 6 75 7 on the Mohs scale, the texture is delicate and tough, most of them are opaque, and very few are translucent or transparent, showing a dazzling glass luster.

Summary. 1. If you want to identify whether a stone is jade or not, I think there are three ways to identify. 2. The first one is to see, because ordinary stone and jade, in fact, there is a big difference on the surface, ordinary stone looks relatively rough and dull, without any luster, but jade is different.

Can you add, I don't quite understand it.

1. If you want to identify whether a stone is jade or not, I think there are three ways to identify. 2. The first one is to see, because ordinary stone and jade, in fact, there is a big difference on the surface, ordinary stone looks relatively rough and dull, without any luster, but jade is different.

1. Identification from appearance

From the appearance of jade to the touch is more round, jade is generally the most likely to form in the area with ore, and jade is the most precious type of ore, so it is generally difficult to find high-quality jade on the river beach, of course, there may be some strange stones, jade feels more round.

2. Identification by water drop method

Pick up the stone and drop it on the surface of the stone with water droplets, if it will not disperse for a long time, it means that it may be jade, first of all, because the density of jade is higher than that of ordinary stones, if the water droplets drop on it, if it spreads out at once, it means that the stone cannot reach the density required by the jade.

3. Lighting verification

Ordinary stones are opaque from any angle, while jade emits a certain amount of light. Sometimes with the help of a magnifying glass and a condenser lightlight. It is mainly used to identify color intensity changes, observe gemstone cleavage, internal inclusions and distinguish transparency.

Precautions for buying jade rough

1. Be careful when large patches of green can be seen in the jadeite incision or window. There is a folk saying that "not afraid of a line, only afraid of a large piece", this large piece is usually cut in the direction of green, that is, parallel to the direction of green to cut a knife or wipe the window, in fact, the thickness of green is only a thin layer. If one piece of rough has already been cut, be sure to research the small pieces that were cut at the time of purchase.

Observe whether the green can be observed and whether the green is likely to extend to the large.

2. Because of the jadeite rough produced by different fields, it has different characteristics, so the first thing to get a piece of jadeite rough is to see which field the jadeite rough comes from, people often say "don't know the field, don't play jadeite", which shows the importance of the jadeite field.

The main differences are: the chemical composition of the elements, the physical density and the specific gravity.

1.In terms of composition, jade has its standard constituent material Ca2(Mg,Fe2+)5(Si4O11)2(OH)2;

2.In terms of the age of formation, the above four stages of the formation of jade can be summarized as follows:

a. Late Mesoproterozoic continental margin marine sedimentary dolomite (one of the jade-forming materials**).

b. Tarim movement at the end of the Proterozoic, regional metamorphism Dolomite metamorphism into dolomite marble (transformation of jade material structure).

c. In the late Hualixi period, the middle acid ** into the activity, the contact metasomatism formed the dolomite marble alteration zone (the material basis of jade).

d. Acidic contact metasomatism and Khotanese jade formation in the late Hualixi intrusion.

Jade is popularly said, the beautiful stone is jade, jade is the essence of the stone, the Buddha Daoya is called the earth relic, is a spiritual stone with the ability to dispel evil and avoid evil, and is widely welcomed in various regions of the world (especially East Asia) The classification of a gemstone.

Broadly speaking, as long as it is a beautiful stone, it is jade, including Lantian jade, Hetian jade, Xiuyan jade, Burmese jade, Nanyang jade, serpentine jade, quartz jade, crystal stone, bloodstone, calcite jade, lapis lazuli, agate, coral, marble jade and other gemstones.
