How to identify the authenticity of zircon 1 Gloss and dispersibility
Zircon has luster and luster. Put the polished zircon countertop down on a piece of white paper, and you can see that the light reflected from the inside of the countertop is very shiny. If you turn the gem slowly, you can see the changing fire color from different facets.
2.birefringence
Zircon has a large birefringence. Align the edge line of the inner bottom edge of the gem, and turn the gem with a magnifying glass of 10 times, and you can see the ghost of the edge line separation.
3. Transparency
Zircon is transparent, but not clear, because the bottom facet of zircon has double shadows.
4. Hardness and brittleness
Zircon ridges are not sharp and smooth. Because of the brittleness of zircon, the ridgeline is easy to be destroyed, and sometimes the ridgeline is incomplete. The main distinguishing features of zircon are: high refractive index, strong luster, high birefringence, high density, high dispersion and typical spectral characteristics. Zircon is rich in color and varies greatly in depth, so zircon can be mixed with gems of any color and transparency. The most easily mixed gems are diamonds, spinels, emeralds, sapphires, rubies, garnets and topaz. The simplest identification method is:
(1) Use a polarizer: Isotropic gemstones can be distinguished from diamonds, spinels and garnets, because zircon is a heterogeneous gemstone with four bright and four dark extinction phenomena under a polarizer, while homogeneous gemstones have full extinction or point extinction.
(2) Zircon can be easily distinguished from other similar gems by measuring refractive index, density, spectrum, observing prism ghosts and inclusions.
(3) Hardness method: using the edges and corners of the gem to lightly stroke the glass surface. If traces can be easily drawn on the glass surface, it is zircon and vice versa.
(4) Magnification detection method: Look at the gem from different directions with a ten-fold magnifying glass. If you look at the other side of the gem through it, if you find that the intersection line of the other side becomes a double shadow, it is zircon. If it is still a single line, it is a fake.
Zircon 1 How to maintain, zircon and cosmetics should be strictly separated. Zircon has oil recovery, which is easy to contaminate oil cosmetics and weaken its surface luster.
2. Take off zircon jewelry when washing your face and taking a bath.
3. Zircon jewelry should not be worn in a polluted environment full of chemical gases. Because all jewels avoid sulfur, emeralds avoid pesticides.
4. Wear less zircon jewelry when sweating.
5. Multiple pieces of jewelry should be placed separately. For example, zircon is hard and easy to scratch other gems.
6. Zircon jewelry should not be put together with drugs. Some drugs will have a chemical reaction on jewelry, making it discolored and deteriorated.
7, zircon jewelry avoid high temperature. Some precious stones are not resistant to high temperature, and are prone to dehydration, cracking or discoloration at high temperature. If opal is not resistant to high temperature, jade will dissolve the wax layer on the surface above 55 degrees Celsius, reducing the gloss of wax.
8, zircon jewelry to avoid violent vibration. Although the bases of many inlaid ornaments are designed firmly, violent vibration is absolutely inappropriate. If you need to knock at the door at work, you should take off your jewelry first.
9. It is normal for zircon silver jewelry to turn black when worn for a long time. You can soak it in ammonia and baking soda water or wipe it with toothpaste, then rinse it with clear water and dry it to restore luster.
The price of zircon is very chaotic. The price of zircon mainly depends on the transparency of zircon. Zircon is very large in size and workmanship. The highest price of zircon is sapphire blue, which has great market demand but insufficient supply. A blue zircon 15 yuan in the market, with a diameter of 6MM, will be cheaper in other colors 10 yuan. Because natural zircon has certain radiation to human body, it is harmful to human body, so we can't directly use it as ornaments when we get natural zircon, so there will be artificial zircon instead of natural zircon in our life, and zircon can be sold by kilogram when it is cut into small objects, except blue, which is about 50 yuan per kilogram!
The price of zircon jewelry Zircon jewelry is basically embedded in silver jewelry. A pair of zircon silver earrings with a diameter of 5.5MM need 99 yuan, a pair of earrings with brighter design need 150 yuan, and a zircon bracelet will cost a little more because of its heavy weight. A bracelet around 260 yuan is very shiny, and a zircon ring is very cheap. A small decorative ring needs 59 yuan.
