True and false agate identification method

Agate has been cherished by the world since ancient times. It is known as one of the ancient seven treasures. It is regarded as a sacred object to ward off evil because of its rich natural gas. With the continuous increase in investment value in recent years, the phenomenon of mixed fish and dragons Inevitably, in order to avoid being deceived, the identification of true and false agate can start from the following aspects:

1. Look at the texture: The essence of agate is colloidal dehydrated silica. Its texture is fine, the structure is fine, the hardness is higher, the specific gravity is larger, and the hand feels smooth and oily. Fake agate is generally made of glass and plastic, with low hardness, light weight, and feels light or slippery. For example, bracelets, agate bracelets are heavier, squeaky sounds are clear and pleasing; glass or plastic bracelets are slightly lighter, and the sound is hoarse and dull;

2, look at the shape: the general agate rough stone is subject to the constraints of its typical agate outer skin, these outer skin can not be artificially imitated, its color has a certain law. It is easy to distinguish the true and false agate rough, especially the agate stone. For example, grape agate, stalactite agate, pictogram agate, etc.;

3, look at the color: agate is a masterpiece of nature, is the darling born in the lava. In addition to its gorgeous colors, it also has an innate birthmark, which is the layered texture of agate. In general, the color is pure, the texture is clear, the true agate; the color is dim, the fuzzy is a fake agate. For example, beading, a piece of fuzzy uniform color is a fake agate; red and yellow (white) form a clear texture between the real agate. The light color is soft agate; the light color thief is dark is a fake agate;

4, look at the water head: mature agate generally has a water head. However, due to the specific causes, the degree of transparency varies. There are also many agates that contain different minerals or impurities to form landscapes, water lines, and pupa. Artificial agate does not have these. In general, the artificial agate has a better head than the true agate, but the color extends from the outside to the inside. It is difficult to form a floating color, a water line, and it is difficult to find a flaw;

5, look at the temperature agate is a high-concentration material, with the characteristics of warm winter and cool summer. Although materials such as glass seem to be agate, they do not have this property. For example, in the winter, the cool agate, the cold and biting is the glass;

6, look at the weight: true agate jewelry is heavier than synthetic agate jewelry;

7, look at the structure: true agate regardless of the unique shape, how complex the architecture is a seamless integration, treasures of heaven. In order to be similar, fake agates must also be processed into collages. No matter how clever they are, they can still find loopholes such as bonding, collage, glue injection, water injection, dyeing, polishing, carving and so on.
