How to choose agate jewelry? When choosing agate necklace, you should pay attention to the color of each bead in the same color, no variegated color, the size of the beads should be appropriate, but also pay attention to the smoothness of the bead. First of all, to choose the color according to your own preferences, the red agate jewelry is the most expensive. Then look up the necklace and see if it is vertical. See if each bead is hanging in a straight line. If the necklace is bent and twisted, it means that some of the beads are deflected, indicating that the processing technique is rough and not worn. Beautiful. How to choose agate jewelry? How to identify water agate The shape of the water agate is mostly irregular, round, elliptical, or oblate, with no sharp edges and a smooth surface. To identify whether there is a water bladder in the agate, the following methods are generally used: 1. Use hearing to determine if there is a water bladder. Put the agate material in both hands, hold it steady, shake it from side to side, close your ears, and listen carefully to the sound of the sloshing in the raw material. Some hollows are large, and there are many liquids, which can make a squeaking and squeaking sound; some have small holes, less water, and the sound of shaking is small or silent, some are too small, or the water is too full, then you can’t hear it. To the sound. 2. Determine whether there is a water bladder by hand. As the water bladder is shaking, the water will rush into the hole in the hole. Then the motion will be sensed to the outside, so that it can be judged that there is no water. The weight of the hand can also be judged to have no water. Water agate agate is watery and watery, and the higher the transparency, the better. 3. Use light to judge that there is no water. The raw material is peeled into water, and the surface is completely wetted. After taking out, the raw material is irradiated with a spotlight or a strong concentrating flashlight, and the raw material is irradiated (i.e., the back surface is irradiated), and then the water in the middle is observed carefully from the front. If there is water, then the water in the lower part of the cavity and the space in the upper part will have a more obvious swaying boundary, that is, while shaking, while observing, if the water biliary is large, the biliary is thin, and the transparency of the raw material is high, the water can be seen. Swing in the hole. The water biliary is wrapped in the agate when it is formed. It is extremely precious. Because there are very few raw materials for good water biliary agate, it is not easy to sculpt valuable crafts. Therefore, the current market is full of fake sacred people, which makes people talk about water biliary agate. "Bile" discoloration. The main counterfeit means of counterfeiting water agate is: (1) After the initial carving of the agate crafts, cut or drill a part that is not easy to be detected, open a hole in the middle, then apply it with a strong glue, and repair the polished finish, posing as a true water bladder. (2) Dry and hydrated, plugged in the hole and filled with water, and the upper part is covered to make it difficult to detect. (3), after accidentally carving the water gallbladder, and then using the same color agate carved into the ornament, it is difficult to see. (4) For the leaking gall bladder, seep the water inward through the crack, and then seal the crack with strong glue or the like after the water enters. False means are sometimes unpredictable, and even experts are inevitably fooled. In some cases, it is true and false to pretend that it is true and false. It is difficult to justify it. It is a fake, and even the dealer’s water-stained agate that he sells is true or false. . There are a few simple ways to identify the true and false of the water agate: (1), look carefully at whether the handicraft carvings are impeccable, if the carvings are not even a seam, it is difficult to say that it is a fake. (2) The inner wall of the water bladder has sputum (blackening) or crystal crystals, which are generally natural, which is the trace left by the formation of the water biliary agate. (3), carefully observe with a 10 times magnifying glass, with a knife or needle tip for questioning, because the agate Mohs hardness is 7, the hardness of the knife is 5 ~ 5.5, the true agate can not draw traces, if the fake part is glued with glue, its The hardness is generally 5, and the knife can be used to draw traces. (4) If there are conditions, please ask the experts for identification and ask for a certificate of gemstone identification. It is worth mentioning that even the water in the natural water agate is not never dry. After all, agate is a mineral aggregate composed of fine quartz crystals. The size of the crystal is only 0.1 to 0.4 μm (1 μm = 0.001 mm), which is difficult to distinguish with the naked eye. Only when the crystal layer as the wall of the water bladder is thick, can the water bladder water never dry for a long time. However, when the crystal layer as the wall of the water bladder is thinner, or the viewing surface is large, or the "sand gallbladder" crystal wall layer is exposed after the carving, the water in the water bladder will slowly evaporate along the gap. The water consumption caused by this slow evaporation is only supplemented by long-term soaking and infiltration of the agate product in the water. In this case, the water in the water agate aquarium is "congenital" or "the day after tomorrow", even experts are difficult to distinguish. How to choose agate jewelry? When there are the following problems, you can ask whether it is true water agate: (1) There is no impurity on the inner wall of the water bladder, and there are traces of carving; (2) The position of the water bladder of the water agate agate is just right, is there such a clever water chest; (3) In appearance, there are doubts about the non-main part, there are traces of pinholes or adhesions, and the needle eye is used for water injection; (4), compared with the real water biliary agate, the price is obviously low Plastic Mattress Cover,Mattress Cover,Twin Mattress Protector,Queen Mattress Protector Hangzhou Dowin Hometextile Co.,Ltd. , https://www.dowinbedding.com
