How to identify true and false lapis lazuli

青金石

First of all, the identification method of pseudo-lapis lazuli in science is not long, but it is very practical!

Synthetic lapis lazuli identification method

1 Transparency: Natural lapis lazuli has a higher transparency. Under strong light transmission, a blue halo is visible, and a lapis lazuli invisible halo is synthesized.

2 color: natural lapis lazuli color, visible yellow pyrite, white calcite and a small amount of dark green diopside, and synthetic lapis lazuli color uniform.

3 inclusions: natural lapis lazuli pyrite inclusions, uneven distribution, pyrite particles of different sizes, and synthetic lapis lazuli is artificially added, evenly distributed, the boundaries of the particles have fixed boundaries.

4 Density: The density of synthetic lapis lazuli is lower than that of natural lapis lazuli, the voids develop, and the weight increases after a period of time in the water.

Dyed lapis lazuli

The lapis lazuli with poor color is dyed into high-quality color, dyed lapis lazuli, the color is even, and sometimes the color is too deep to be concentrated together. The magnified observation shows that the color is distributed along the crack, and the dye particles are gathered at the crack. Wipe with acetone swabs or alcohol with a cotton swab.

In order to help everyone distinguish fakes, I bought one myself, which is cheap anyway. what's everyone's opinon on this? Top level? It's too easy to make it impossible to distinguish from photos. But things are different:

First, it is not as lustrous as green gold, the color is dull, the plastic feels obvious; the second, not delicate, feels awkward by hand, does not run; third, there are white spots in some places, just like a hard small The rice grain sticks to it; fourth, some so-called small pits, real green gold, some of the green gold surface is very smooth, where are the pits and small ripples?

Specifically, the player needs to see it himself. Remember, there will be a price difference between the merchants, but if there is an outrageous leak, then pay attention to it. This kind of merchant is often not stupid, will you pay for the blood?

You must know that the price of real goods will never be faked, and the green gold will not be plastic.

All in all, no matter how far it is, as long as you get to the market, you will inevitably encounter counterfeit lapis lazuli. Xiao Bian feels that in this era of scams and swindlers, in addition to the practical knowledge of lapis lazuli, Quasi-reliable businesses are even more important. A good business is not only selling the real goods to you, but also the indicator light on your wenwan road.
