The common colors of topaz, apatite, colored zircon, glass and artificial spinel are several differences. It can be seen that they differ from the physical characteristics of the imitation. Larger and easier to identify.
1, sapphire
Hardness 7.5 Density (g/cm3) Refractive index 2.67-2.90 Birefringence 1.560-1.6000.006 Characteristic four-time shading change under polarizing mirror
2, zircon
Hardness 7.5 Density (g/cm3) 4.69 Refractive index 1.926-1.985 Birefringence 0.059 Characteristics under polarizer No
3, topaz
Hardness 8.0 density (g/cm3) 3.59 refractive index 1.610-1.620 birefringence 0.010
Artificial spinel hardness 8.0 density (g / cm3) 3.63 refractive index 1.728 birefringence without polarizer characteristics
4, glass
Hardness 7.0 density (g/cm3) 2.37 refractive index 1.50 birefringence without polarizer characteristics
Apatite hardness 8.0 density (g/cm3) 2.9-3.1 refractive index 1.630-1.667 birefringence 0.002-0.005
In addition, the color of aquamarine is sky blue, pale sky blue, glass luster, and less inclusions, but tubular bodies can be seen, usually hollow or liquid-filled slender tubular bodies, which can be cut out if arranged in a dense orientation. Cat eye effect.
Precautions
The economic evaluation of aquamarine is based on color, transparency, weight, etc. It is usually good in color, internal flawless, and heavy, and the value is also high.
Popular science knowledge
The information found on the Internet shows that everyone is arguing about the problem of topaz dyeing as a sales of Aquamarine. Weibo authority has a rich experience of the older generation's answer: "Topa stone its scientific name
It is called topaz. The color is mostly yellow or colorless. The blue topaz that everyone sees on the market is mostly neutron radiation, electron accelerator bombardment/CO60 irradiation and heating method. There is no real blue. of
Topa? I don't dare to make a 100% guarantee, but I can only say that it should be no for my eyes! "The specific point still needs everyone's own judgment. Hailanbao identification related knowledge, for the sea blue
Bao's evaluation is that there are so many people who like Hailanbao. The beautiful and beautiful sea blue ore is full of romantic marine flavor, and it is also reminiscent of the blue sky. The transparent to translucent blue gem makes people feel very good.
