What is Laokeng ice jade? We must have heard of Laokeng ice jadeite, but many people don't know it very well. Do you know what Laokeng ice jadeite is? What's the difference with ordinary jadeite? Now let's learn about it
Introduction to Laokeng ice Jadeite
Laokeng ice jadeite is thick, bright and eye-catching, positive and not evil, Yang and pleasing to the eye, uniform and pleasing to the eye. Jadeite crystal is fine granular with uniform particle size. The grain size can be distinguished by the naked eye (it can not be distinguished by the naked eye. The jadeite with crystal must be below coarse waxy. The jadeite is pure, free of impurities, fine texture, no cracked grain, cotton grain or rare. The sound of knocking the jade body is metallic, transparent, glassy, and the appearance of the jade body looks like ice crystal.
Color is the first factor to evaluate Laokeng ice jadeite. The criteria for a good color are: positive, strong, positive and uniform. Positive: refers to the range of hues, which depends on the ratio of primary color to secondary color, that is, pure green is required, and other colors are not mixed. For example, oil blue is often mixed in oil blue, which will reduce the value. Strong: refers to the depth of color, as far as jadeite green is concerned The best concentration is between 70% and 80%, and 90% is too strong. Yang: refers to the bright degree of the color of jadeite. The bright degree of jadeite is mainly determined by the proportion of green and black or gray in jadeite. More green proportion will make the color bright. If more black or gray, the color will be gray. Experts often use image methods to represent the bright Yang of the color. For example, yellow Poplar green, parrot green, green onion heart green and pepper green all refer to the color of fresh Yang. Spinach green, oil green, river green and black green refer to the dull dark green. The fresher the sun, the higher the natural value. All: refers to the uniformity of the color distribution of jadeite. Generally, the color distribution of jadeite is uneven. It is not easy to obtain jadeite with uniform color distribution The best color: it should be pure green, with a green concentration of 70% - 80%, bright Yan Yang and uniform color distribution. This kind of high-grade jadeite is called Laokeng by experts.
The jadeite crystal is fine granular, with uniform grain size, which can be distinguished by the naked eye. The jadeite is pure without impurities, fine texture, no cracked grain, cotton grain or rare. The sound of striking the jade body is metallic, transparent, glassy, and the appearance of the jade body looks like ice crystals. Some subdivide the ice species into ice species and quasi ice species. Ice has sufficient water head (1.5 moisture), which is very transparent and excellent in texture. Quasi ice has good water head (1 moisture), translucent and good in texture. Jewelry can be processed into plain shape (oval egg shape, pear shape, square, heart shape, horse eye shape, saddle shape and nostalgic shape), pendant (multi display surface), pendant, bracelet and round bead, which are high-grade.
Laokeng jadeite with good water will emit a soft luster inside, which is the fluorescence of Laokeng jadeite. However, the new jadeite usually does not have fluorescence, so this is one of the unique characteristics of Laokeng jadeite.
Supplementary note: put the jadeite under the fluorescent lamp and observe its color change. Goods a and C do not change, goods B have fluorescence and turn white. Goods C are dyed, so its color is distributed along the cracks and unevenly. Careful observation can be seen with the naked eye. The specific explanations are as follows:
A-cargo jadeite, natural jadeite, is a natural jadeite with natural color and results without chemical treatment.
B jadeite, bleached glue injected jadeite, is a jadeite after strong acid cleaning and glue injection. Strong acid soaking and cleaning will help to improve the transparency and color of jadeite.
C jadeite, dyed jadeite, is a jadeite treated by artificial coloring, which is usually colored with organic or inorganic dyes.
B + C jadeite is a kind of jadeite that has undergone strong acid cleaning, glue injection and artificial coloring treatment at the same time.
The difference between old pit and new pit ice Jadeite
What does the old pit of jadeite mean? What is the new pit of jadeite? This may be a difficult problem that many jadeite lovers have to face at first. In the eyes of jade friends, the older the jadeite is, the better. In fact, when it comes to the year of jadeite, we should first understand the concept of new and old. This new always refers to the sequence in which jadeite is formed underground, that is, the year and year referred to by geologists. It still refers to people's hair The order of Ming jadeite? Maybe people bought the products and kept them for a long time?
1. Laokeng and xinkeng are actually divided according to the years when people invented and mined jadeite. According to the geological concept, they formed in the same geological age in the dark. The secondary deposits deposited by river channels were deposited by river channels transported to the riverbed in the Quaternary era, perhaps later formed in time. Some experts invented jadeite in 'Laokeng' from temporary practice The jade is of good quality and sufficient moisture. Can it be formed by soaking in the river temporarily and water entering the crystal? In fact, it is not. The jade invented in the river sedimentary deposit is of good quality, high color, fine quality and good colorlessness. Perhaps a reasonable explanation can be obtained from geology.
2. In fact, the jadeite open bed has these scenery, as do other gem deposits. For example, the diamond in placer is of better quality than the primary deposit. This is because the primary deposit actually has various ores of different quality, which are transported by water and deposited into secondary deposits. Some of the poor quality jadeite will be obtained if there are cracks, coarse grains, mixed structures and impure jadeite Natural sorting and elimination. For those who live in the river bed at the end, it is mainly jadeite with dense texture and fine structure. This kind of jadeite is often colorless, but it is not caused by water entering people. Water can not enter the jadeite crystal. The quality of the jadeite in Laokeng is better because it is so related. The skin on the surface of this kind of jadeite is affected when the jadeite is exposed to the ground The corrosion and hydrolysis to the natural world precipitates some iron and manganese contained in it into a kind of corrosive iron or corrosive manganese. It adheres to its appearance and forms a shell, just like an infrequently used knife. Its appearance contains the strange reason of corrosion and rust.
3. Compared with the new pit, the quality of the old pit is good, but the quality of the new pit is relatively poor. It may be said that the quality of the jadeite in the 'old pit' is better, but there are only relatively few Jadeites in the new pit. This is the final result of unselected. The old pit ice jadeite Bracelet refers to those high-quality bracelets with good texture and less cotton wadding. The texture of the ice jadeite is also very transparent, but it is better than that of the new pit As the name suggests, the glass jadeite is as pure as glass. If there are any slight impurities inside, they will be exposed without doubt, while the transparency of ice jadeite is second. Although it is also very transparent, there are a little more impurities after all. Laokeng ice jadeite bracelet has excellent water head, light or colorless color, less cotton locks and crystal clear. It is a high-grade jadeite bracelet.
Laokeng ice jadeite bracelet also looks pure and transparent. Different from Laokeng glass jadeite bracelet, it is only three parts warm, but seven parts cold. Although ice jadeite is not as precious as glass jadeite. The best quality and highest transparency of Laokeng ice jadeite bracelet is often called high ice, which means the best one among ice, high ice and The glass is almost the same. The ice has the same glass luster, but the color is cold and glittering. According to the number of cotton locks, the ice bracelet is flashy and quiet. It is an excellent jewelry for mature women!
How to buy Laokeng ice Jadeite
Laokeng ice jadeite is the leader of the jadeite family. The color of Laokeng ice jadeite meets the requirements of thick, Yang, positive and harmony. The color is dark green, evenly distributed, colorful and bright, fine texture and good transparency. Many celebrities like Laokeng ice jadeite. There is a jargon in the collection industry that "gold is valuable and jade is priceless". The jade here refers to jadeite, which means that jadeite is invaluable When it comes to jadeite, we have to talk about the three major jadeite brands. In the jadeite collection industry, many experienced players basically don't buy the three major jadeite brands. The main reason is that the water in this industry is too deep, and there are too many people who confuse the fake with the real and shoddy. Even experienced people can't avoid being cheated. What's more, ordinary consumers? The price of Laokeng ice jadeite Gao, how can we buy Laokeng ice jadeite bracelets? Next, Xiaobian will provide you with some tips on the purchase of natural Laokeng ice jadeite bracelets. In fact, we should pay special attention to the color, base, grain crack, type and variety of jadeite bracelets.
1. First of all, we should pay attention to the color of jadeite bracelet, which has a direct impact on its price - there is a lot of difference between a little color and a large section of color; secondly, we should look at the color intensity, and the color with different intensity will have a lot of difference in price; thirdly, we should look at the fresh and dark color, the color price of fresh Yang will be very high, and the color with relatively dim color will have a lot of difference in price Much lower. The above two points are generally noticed by buyers when choosing jadeite bracelets, but the aggregation and dispersion of color is relatively easy to ignore.
2、 Types of jadeite Bracelets
In addition to color, what we can most intuitively observe is the shape of bracelet. Emerald bracelet can be divided into round bar and flat bar, round and imperial concubine bracelet, as well as carved and plain bracelet. Round bar and flat bar refer to the shape of Bracelet cross section, round and imperial concubine refer to the shape of Bracelet front, and carved and plain Bracelet refer to the shape of Bracelet surface.
What experts say about the thickness of the band refers to the width of the bracelet wall. It is worth mentioning that most of the carved jade bracelets we encounter have cracks, and the surface needs to be decorated by carvers. For example, the bracelet of Erlong playing with beads looks very beautiful, but it is generally cracked, so it is not worth collecting. As a collection level bracelet, it should be of plain shape.
3、 Shape and system of jadeite Bracelet
When the bracelet is of the same kind and color, the width and thickness of the mouth are different, and the price will vary greatly. Generally, the price is higher if the material is wide. The thickness is reflected in the 'height' on the cross section of the bracelet, and the high-grade Bracelet must be thicker and fuller.
The inner diameter of the ring mouth bracelet will also have an impact on the price. For bracelets of the same kind and color, the larger the ring mouth, the higher the price. In general, bracelets with fine and transparent germplasm, fresh and pure color, plain shape, thick materials and no lock crack are of great collection value.
In addition to considering the collection value, the size of the ring mouth and the thickness of the strip mouth of the jade bracelet should also be determined according to the size of the individual palm. What is suitable for yourself is the best!
4、 The base of an emerald bracelet
The colors and types of jadeite bracelets are generally noticed when selecting jadeite bracelets, but the most important and easily mistaken thing when looking at bracelets is to look at its base (other than green).
Under normal circumstances, the green part of jadeite will be very good and transparent, but the non green part will be particularly dry and not transparent, which is what experts call "water where the Dragon comes". Two bracelets with the same green part may differ many times in price due to different backgrounds. Among the common Bracelets in the market, glass, ice and ice waxes belong to medium and high grade, and waxy species belong to waxy species In the middle and low grades, of course, these are relatively speaking. Planting water is an important standard to judge the value of bracelets, but it is not the only standard.
