Recently, synthetic lapis lazuli appeared at the exhibition. Features: uniform color, no gold and no white, almost no structure and inclusions. After the finished product is polished, ordinary consumers are hard to see. As long as the market is bullish, it will play the "true and false monkey king" drama every day, so you need a pair of Buddha's eye to open the cloud to see the real thing. Natural lapis lazuli will contain more or less "gold" and "white", and there is no gold or white lapis lazuli, which is very rare. Xiao Pan reminds everyone here that if you see pure and noisy lapis lazuli, you need to polish your eyes and distinguish them from hardness, gloss and inclusions. It is best to get a qualified appraisal center to find an expert. The finest lapis lazuli is produced in Afghanistan. In addition, lapis lazuli is also produced in Myanmar, Angola, Chile, and Pakistan. The best lapis lazuli is all green without yellow and white variegated. There are two kinds of the best of the cornflower blue and the emperor blue. Among them, the emperor green looks more stable, the blue cornflowers in the blue and the purple, the jade has a bright oil and the light is good. It is also very popular if it is accompanied by a uniform gold pyrite. The currently known artificial lapis lazuli is a synthetic "lapisma" component produced by the Frenchman Gilson. This material can have a pyrite inclusion and its composition is very similar to that of natural products. Similar to lapis lazuli, the difference is that the refractive index and hardness are significantly different from lapis lazuli. This "synthetic" lapis lazuli leaves white spots after acid drops, while natural lapis lazuli does not. For the synthetic lapis lazuli, you can start from the following four points to go to the false! transparency Illumination by hand, if the light is strong enough, or if it is thin enough, the replica can be partially translucent, while natural lapis lazuli does not. colour The natural lapis lazuli color is mixed with yellow pyrite, white calcite and a small amount of dark green diopside. The synthetic lapis lazuli color is uniform. Envelope The natural lapis lazuli pyrite inclusions are unevenly distributed, and the pyrite particles are of different sizes, while the synthetic lapis lazuli is artificially added, evenly distributed, and the edges of the particles have fixed boundaries. density The synthetic lapis lazuli has a lower density than the natural lapis lazuli, the voids develop, and the weight increases after a period of time in the water. So, how can I buy real natural lapis lazuli? 1. First of all, the purchase is not cheap; now there are some imitation or dyed lapis lazuli on the market, just to confuse people who want to buy cheap blue lapis lazuli. Always remember that "a price is worth the price", when you encounter pure lapis lazuli, and its price is unexpectedly cheap, then you have to ask why. 2, secondly, don't pursue perfection; don't always think about buying pure blue without gold and white. Natural lapis lazuli, most of them will have some impurities in it, pure blue lapis lazuli is rare, if a whole string of lapis lazuli is the same color, there is no trace of variegated attention. 3. Finally, finding a reliable business is the last word. One of the shortcuts to reduce deception is to find a reliable business. The price level of each price is different, but at the very least, it can be fidelity and quality.
