Emerald blends the essence and creation of nature for hundreds of millions of years. It is the spiritual thing that people communicate with nature, especially the glass jade, which is rare in the world. Because jade has a wide variety of resources and scarce resources, it is often used by counterfeiters. They use various materials to counterfeit jade, and imitation jade glass is the oldest and most common fake material. For the different characteristics of the two, we can use the naked eye to observe and use the instrument method to identify jade and pseudo-pseudoglass.
When we go out for a trip, we often visit some low-end jade shops. The shopkeepers often use the dice to sell at the price of jade, which are actually just imitation jade glass.
Several methods for identifying jade and imitation jade glass.
It is distinguished from the color distribution: the natural jade color is mostly silky and flaky, which is difficult to achieve uniformity. It is a very high-grade variety when the color is very rare, and then the green color is usually accompanied by transparent color or its color. As a foil, the color of imitation jade glass is usually evenly distributed in a streamlined shape. If it is devitrified glass, the pattern is grassy. The most difficult to distinguish is the so-called jadeite imitation of South African jade glass. Its green shape is like a fern. Plants, to put it bluntly, are plants that resemble the leaves of the pinnae, which is extremely confusing with the patchy distribution of true jade.
Identification from the cleanliness: natural jadeite contains other mineral inclusions and cracks, so the clarity is good, you will find a small amount of tiny cracks, white cotton, black spots or impurities; there will be bubbles in the jade glass, in Under the magnifying glass or under the light, you see a green ball.
Identification from the specific gravity: This is the easiest, the relative density of jadeite is 3.2-3.39, which is larger than the relative density of nephrite; the relative density of imitation jade glass is only 2.5, unless the chemically treated glass can generally distinguish from the specific gravity. .
For the color of the extra green, the transparency of the good jade must pay more attention to see if there are signs of natural jade in it, such as a blocky, slightly transparent white stone.
