How to identify the authenticity of agate beads, how to identify the authenticity of agate beads

Agate is a gemstone commonly used in jewelry inlays and carving crafts. The method of distinguishing between true and false is as follows:

1) Color: The color of real agate is bright and bright, and the color and light of false agate are poor, and the contrast between the two is more obvious. The natural red agate is distinctly colored, and the bands are very distinct, and if you look closely, you can see the dense array of fine red spots in the red bands.

The fake agate chimney bottle imitated by stone, most of which are petal-shaped patterns at the bottom, forming a "chrysanthemum bottom"; The dyed blue agate is bright and uniform in color, giving people a false feeling.

2) Texture: Fake agate is mostly imitated by stone, which is softer than real agate, and traces can be drawn on the fake agate with jade, while the real product can not be drawn.

3) Process quality: The production process of high-quality high agate is strict and advanced, so the surface brightness is good, the inlay is firm and circumferential, and there are no scratches and cracks.

Agate stone is available in natural color and post-processing dyeing. The main natural colors are red, amber and white. The best blue and purple agate jewelry on the market is not a natural color, it is dyed after processing, and it will fade after a few years.

How to distinguish real and fake agate jewelry? It can be identified in three ways.

Transparency: The transparency of real agate is not as good as that of synthetic agate, it is slightly chaotic, and some can see natural waterlines or "clouds", while synthetic agate has good transparency, as transparent as a glass ball.

Weight: Real agate jewelry is a bit heavier than synthetic agate jewelry.

Temperature: Real agate is warm in winter and cool in summer, while artificial agate changes with the outside temperature, it becomes hot when it's hot, and it gets cooler when it's cold.

Identifying real and fake agate jewelry can be divided into three aspects:

1. Transparency: The transparency of real agate is not as good as that of false agate, slightly chaotic, some can see natural waterlines or clouds, while fake agate has good transparency, as transparent as a glass ball;

2. Weight: Real agate jewelry is heavier than fake agate jewelry;

3. Temperature: Real agate is warm in winter and cool in summer, while false agate changes with the outside temperature.

The identification of agate is mainly from the following aspects:

First, from the perspective of texture, the Mohs hardness of real agate is above 7. The intuitive way is to scrape it with jade, leaving no marks. If there is a trace, it is a false agate.

Second, from the perspective of transparency, the transparency of real agate is not particularly good, and it will taste a little messy, but it is not transparent enough. At first glance, it won't look so bright, and you'll see some natural waterlines or dots inside. Imitation agate is generally transparent and uniform.

Like glass, agate that is too transparent is fake.

Third, in terms of weight, like many jewelry, real agate is slightly heavier than fake agate, and it is difficult to grasp the feel, which cannot be judged by this.

Fourth, from the point of view of temperature, natural agate does not change with the outside temperature, it is warm in winter and cool in summer, just like an air conditioner. Artificial agate, on the other hand, changes with the change of outside temperature, that is, it gets cold in winter and hot in summer. In addition to synthetic agate, there are also parts made of high-quality stones, and these imitation agates are cool to the touch.

At this time, we will further identify it in combination with the following details.

5.In terms of color, the biggest feature of the color of natural agate is the glutinous texture and glutinous luster. Imitation agate does not have this feeling.

But there are also some merchants who coat the imitation agate with a thin layer of organic matter to make it look like wax. So, when you buy it, use your nails a few more times.

Sixth, from a craft point of view, this last point is actually common to many jewelry. It's really a natural good agate, and the workmanship is not bad. The inlaid agate will be very firm, the surface will be polished very smooth, and there will generally be no cracks.
