If you accidentally buy fake goods, then how do you like to identify the true and false lapis lazuli? How to choose lapis lazuli? One: the lapis lazuli is difficult to distinguish between true and false In general, lapis lazuli is mainly dyed and filled, which is difficult for ordinary people to identify. It seems that there is not much difference on the surface, but fake lapis lazuli usually has several characteristics. 1 color is uniform, no gold and no white. The lapis lazuli that is faked by dyeing usually has a uniform color and looks like a perfect one, but the general price is lower. Be cautious when encountering this type of lapis lazuli. 2 False lapis lazuli is light on hand. Some magnetic beads are faked lapis lazuli because their density is relatively low. Although the color is pure and lustrous, you can know the true and false as long as you can use it. 3 lapis lazuli can be magnified and observed. There will be some semi-circular pits in the bubble. The real lapis lazuli is polished and polished, and the surface will not be pitted after being enlarged. 4 fake lapis lazuli is synthetically fired and has a sense of depression. After the control of lapis lazuli, some small fractures can be observed. If you look closely, you can see some clues. Second, true and false lapis lazuli identification 1, strong light flashlight irradiation Some fake lapis lazuli is made of quartzite dyed, and the surface has the phenomenon of heating and bursting. If it is illuminated by strong light, it can be easily penetrated. This kind of "laminite" must be fake! 2, alcohol wipe Many dyed lapis lazuli can be identified by alcohol wiping, although these dyed lapis lazuli will not fade, but fading will occur as long as it is wiped with alcohol. 3, 掂 weight The fake lapis lazuli is lighter and has no pressure, so it can be placed in the hand to measure the weight of the lapis lazuli. Third, how to choose lapis lazuli 1, choose the color The color depth is a standard for evaluating the level of lapis lazuli. Generally, the lapis lazuli with the deep color is the best, and of course the color should be rich and pure. 2, look at impurities The selection of lapis lazuli is the same as other jade. The less impurities, the better. There are white or porphyritic minerals in the general color of lapis lazuli, which has a great influence on the quality of lapis lazuli. 3, look at the crack The lapis lazuli often cracks, and the cracked lapis lazuli is naturally of poor quality, so be sure to avoid it when purchasing. 4, see the process Lapis lazuli is usually used for beading and some jewellery, so there are also requirements for the lapis lazuli process. Generally, the lapis lazuli cut into flat shape is the highest quality, and the lapis lazuli polished to the curved surface is worse.
