The best sapphire should be "vermiculite chrysanthemum". It refers to the color of the gemstone, which is a little purple, as if the blue velvet color. The most common glass on the market is glass. In fact, it is easier to identify glass. The glass came out of the high temperature. After cooling, it contracted naturally, and the plane was sunken inward. This is not easy to find the naked eye. You must use the magnifying glass to use the magnifying glass, you cannot focus directly on the line. You should be obliquely focused. It is easy to find the concave surface and the depression, usually glass. The polishing and polishing of gems usually achieve a very flat effect. . Another identification method is that there are many types of parcels in the glass. The most common is air bubbles, while gems do not have bubbles. The bubbles in the glass can be found with 10 times the magnifying glass observation. Extension information: 1, Kashmir sapphire: It is a translucent chrysanthemum blue (purple blue) velvet sapphire, which has been mining for more than 100 years. The authentic Kashmir sapphire has a low output due to the factors such as terrain and climate, so the output is low. In recent years, it lacks high -quality output. However, it can still be seen in the market. 2, Myanmar sapphire: Extremely high -quality thick blue or blue jewels, minus some colors and some blacks appear under artificial light sources. Kashmir sapphire is not characterized by this. 3, Thai sapphire: Very dark blue sapphire, blue and black (American gem market) in the sun; or the chronic blue and velvet gemstone (British Gem Market), which is worse than Kashmir sapphire. In the United States, this kind of sapphire is also poor. 4, Sri Lanka sapphire: Dark gray blue to light blue -purple, with obvious glorious sapphire; when it contains a large amount of needle -shaped and flocculent buns, the glory is reduced and slightly gray. Color is often uneven (such as straps, stripes, etc.). Sri Lanka produced high -quality sapphire in history, enduring, is a list of good quality (a minority can reach the best).
When it comes to the best sapphire, you must not help but say that Kashmir's Chicanic chrysanthemum jewel is. This is the world's recognized top sapphire. The purple tone adds a sense of agility, which is not the most unique place of Kashmir Yasan chrysanthemum. A very large feature of Kashmir Sapphire is that there is a white sheet inside the gemstone, which allows the gemstone to show a velvet -like texture as a whole, which is beautiful and unique. At the beginning, the chrysanthemum sapphire of the carhard refers to the velvet -like sapphire sapphire produced from Kashmir. Unfortunately, the Kashmir sapphire was discovered in the middle of only ten years at the end of the mining. Later The level no longer has the significance of origin. Kashmir chrysanthemums are the best sapphire in the legend, and now they are basically not seen in the market. The high -quality sapphire in the market now is the royal sapphire. Royal Blue is a very unique color. The rich blue has a slight purple. It is difficult to express any instrument, especially the royal sapphire made in Myanmar in the market High popularity and recognition are very popular. To judge whether it is a royal blue gemstone, the easiest way is to understand through the jewelry identification certificate, and then look at it, it is not difficult to judge after accumulating a certain experience. In addition to the color, the clarity, weight, and cutting of sapphire are very important. The cleaner the clarity, the better the carat number, the more rare, the more rare. The quality element can judge the sapphire.

The current market is used to impersonate sapphire, usually blue spinel, library stone, blue vermiculite, Dong Qingshi, etc. This is all of the low -value crystal stones. When purchasing, it must be purchased. The seller must be required to issue an appraisal with national recognition.n2. Whether the dripping water spreads the mass density of sapphire. When dripping a drop of water on the surface, the water droplets can keep the water droplet shape without dispersing. Conversely, the water droplets spread immediately as the ordinary crystal.n3. Whether it is easy to draw the sapphire hardness of the scratch is 9, second only to diamonds, and the knife cannot draw traces on the sapphire, and the counterfeit sapphire is easy to draw traces with a knife.n4. Whether the gloss is changing, the real sapphire looks light under the strong light, the color in the sun looks deep, and the counterfeit sapphire will not change the gloss.n5. Whether there is temperature changes when touching the real sapphire heat transfer is relatively fast.

The best sapphire should be "vermiculite chrysanthemum". It refers to the color of the gemstone, which is a little purple, as if the blue velvet color. There is no impurities, transparent. Such sapphire prices are also very high. "Strange Sapphire" first does not meet national regulations from the name. State regulations do not allow the names of consumers such as place names and names to confuse consumers. There is no way you say whether this situation is really or false, even if there are really artificial synthesis and natural differences. If it is double -colored, it should be fake, 4*6mm, 10 pieces should not be available for a few hundred dollars. If the gem looks more transparent and the interior is very clean, it is artificially synthesized. The interior of natural gems is not very transparent. Give you a advice, no matter what time, jewelry is a price and one point, it is absolutely not cheap. In addition, sapphire belongs to one of the five precious gems in the world. Merchants are generally embedded in 18K gold, and foreign countries use 14K or 9K gold inlaid. None of the silver inlaid will be a good gem, which is appropriate to match the ingredients. So if you do n’t understand jewelry, just see if his workmanship is exquisite, you can probably know the level of this gem.
How to identify and choose sapphire how to identify and choose various jewelry inlaid with sapphire in sapphire is brilliant. It is cool to wear in summer. Wearing in winter makes people feel the spring breeze. This is the charm of sapphire. When you choose a sapphire jewelry that is good, you will definitely feel comfortable and satisfied. So, how to choose sapphire? First of all, it can correctly identify sapphire. The steps of identifying sapphire are the same as Ruby, that is, divided into two steps. The first step is to distinguish the sapphire from other blue gems; the second step is to identify the natural products of the sapped ancient stone with artificial products. Confused with sapphires: salamanders, blue spar, blue electrical stones, blue cone ore, Dong Qingshi, Tanzanite, etc. Like ruby, the difference between sapphire and other blue gemstones, mainly*hardness tests. Because the Mo's hardness of sapphire is 9, second only to diamonds, the other possible substitutes and counterfeit products are lower than it. For the finished products that have been picked up, it can be used to scratch yellow jade and crystal. It can be roughly sure if it is sapphire. In addition, according to other characteristics such as the proportion and refractive index, it can distinguish the substitutes that are easily confused with sapphire. The proportion of sapphire is 3.97-4.08 and the refractive index is 1.766-1.744. Blue -tideline chinensis: hardness 8, a proportion of 3.6-3.8, and a single refractive index is generally 1.72. The blue of the blue spylite is a gray blue. There is no two -way color, which is different from sapphire, which is a more available method. In addition, the blue spikes under the filter color are red tone; the artificial spinel is orange tone, while the sapphire does not change color. Sometimes artificial spinels are also impersonated with sapphires. Because of cobalt elements, red flashing is common under strong light. Blue electroleen: Hardness 7, a gravity of 3.05, and a refractive index of 1.62-1.65, which are lower than sapphire. Generally there is no response under the filter. But chromium -containing electrical stones have a bright infrared appearance under the color filter. The blue of electrical stones is usually dark green and green. Experienced people can recognize at a glance. The refractive index and absorption spectrum are more available. Tanzanite: Hardness is 6.5-7, the proportion is 3.5, and the refractive index is 1.69-1.70, which is produced in Tanzania. It is actually a blue transparent curtain stone, the ingredients of calcium and aluminum silicate. The color is 2 % water -containing sodium 0.02 %. There is a developmental surface, which is not easy to cut. The naked eye can clearly see the three colors (deep blue, purple red and light green colors), so there are obvious color changes in all directions in Tanzanite, while sapphire only has two colors. Dong Qingshi: Hardness 7, a proportion of 2.59, a refractive index of 1.54-1.55, the color is obvious, dark and gloomy, no bright and bright with sapphire, and strong three -color. The direction is cute purple and blue, and the other direction is pale yellow. Compared with sapphire, it is very different from all aspects. Blue cone ore: hardness of 5-5.6, a proportion of 3.67, and a refractive index of 1.78. The refractive index is almost similar to sapphire. But double refraction 0.047 is much larger than sapphire. There is much more scattered than sapphire, so the appearance looks dazzling. Blue crystal: hardness of 4-6, a proportion of 3.69, and a refractive index of 1.72, the hardness of each direction changes greatly. The blue spar pillar is easy to split and not easy to cut. This is very easy to distinguish from sapphire. Dong Qingshi, blue cone ore and blue spar are generally very favorite treasures that collectors are very favorite, and rarely make accessories. After the sapphire is distinguished from other blue gems, the second step can be identified, that is, to identify the sapphire natural product with the candidate. Whether it is natural or artificial sapphire, its mineral composition is rigid, and their physical and chemical properties are extremely similar. This is to be identified by carefully observing its morphological characteristics and production lines. From the perspective of form, unprocessed natural sapphires often have hexagonal barrels or columnar. And artificial products, the appearance seems to be an inverted or a short carrot shape, without clear edges and corners. Natural sapphire is very slow in nature in nature, so that the "hexagonal growth line" that is parallel to hexagonal crystals is also called "hexagonal production ring band". If only a part of this growth line can be found in parallel lines. Any sapphire with such parallel hexagonal growth line or growth ring band must be natural. The artificial sapphire is generated in the high temperature melting furnace. The crystallization time is very short. There is no time to arrange it along the crystal direction of the hexagonal shape. And gradually formed a curved "arc -shaped growth line". Any sapphire with such an arc -shaped growth line or ring -shaped straps must be artificial products. It should be noted that the above recognition method is also applicable to identifying natural rubies and artificial rubies. How to choose good sapphire in sapphire? This is mainly to pay attention to the color of sapphire. In terms of color and color levels, the blue sapphire can be divided into many types. The best one is the blue chrysanthemum (blue hibiscus) with soft and luster. This blue gem with a strong mysterious color forms a sharp contrast with a strong vitality. This sapphire is only produced in Kashmir, so it is also called "Kashmir sapphire". Like Ruby, the best sapphire has starlight effects, and six light inside the gemstone is launched around. There is a 563 -carat starlight sapphire called "India Star" inside the Natural Museum of the United States. The color of sapphire is not good -looking, and the value is low, but the sapphire should not be too deep. The blue is too deep and lacks angry and light, and it loses its characteristics. Good quality sapphire should be uniform, without flaws and impurities. Pure blue treasures should have sugarcane or "cicada wings" like "emerald". In short, the color of sapphire should be moderate and shaded, and sapphires also have light shots and grinding petals. Sapphire is a precious gem. Those who buy a darker color should be thinner and those who buy light colors should be worn thicker.
