The red color of the South Red Agate symbolizes good luck in China , so it is also very popular with people. There are also many collectors. So how do you choose when you buy South Red Agate?
The main reason why Nanhong Agate is popular with people is that it is bright red. So when we buy South Red Agate, we must first look at its color. If the color of South Red Agate is subdivided, it can reach more than a dozen. It can be roughly divided into Jinhong, Persimmon Red, Rose Red, Cherry Red, Red and White, etc. Among them, Jinhong is the best with the feeling of satin, the price is very expensive, and the other is called persimmon. The red south red agate is a popular high-grade south red agate in recent years. This kind of south red agate has a high collection value. If the collectors want to collect the investment, such as the red red agate, the persimmon red is a better choice. .
Picking a South Red Agate can start with the following:
1. Color: The true agate color is bright and bright, and the color and light of the fake agate are both poor. The contrast between the two is more obvious. The natural red agate is well-defined in color and the strips are very visible. Careful observation reveals densely arranged small red spots at the red strips. The fake agate smokers made of stone imitation are mostly petal-shaped at the bottom, forming a "chrysanthemum bottom"; while the dyed blue agate is bright and uniform, giving a false feeling.
2, texture: fake agate is mostly stone imitation, softer than agate texture, with jade on the fake agate can be traced, but the real thing can not be drawn. On the surface, there are few flaws in the real agate, and there are more inferior qualities.
3, process quality: high-quality high-agate production process is strict and advanced, so the surface brightness is good, the setting is firm, Zhou Zheng, no scratches, cracks.
4, level: water agate is the most precious variety of agate, characterized by a closed cavity in the agate containing water.
All grades of agate are best in red, blue, purple and pink, and require transparency, no impurities, no sand, no cracks. Among them, those with a weight of 4.5 kg or more are special, and those with a weight of 1.5 kg or more are one. Grade, 0.5-1.5 kg is secondary.
5. When purchasing agate, it should be distinguished from its four parts: color, transparency, material and temperature:
Color characteristics: true agate color is fresh and active, pure, heavy, and harmonious; while the color and light of fake agate are not natural, often fascinating. Some of the finished products may be from old pits with high pH, ​​usually with reduced gloss, reduced chromaticity, reduced transparency, and of course, the change of identity due to the precious aesthetics of the surface aging mottle.
6, the degree of transparency: true agate transparency is not high (otherwise has reached the crystal boundary), and some can see the natural water line or "cloud" "filament". The synthetic agate has good transparency and is even transparent like a glass ball, which is often unnatural.
7, material: fake agate is imitation with other stone materials, especially the material is fragile or soft. Usually, agate is relatively strong, and most agates that are not affected by acid and alkali can be scratched on the glass. True agate jewelry is heavier than synthetic agate jewelry.
8, temperature: true agate (especially not affected by acid and alkali and other factors affecting the new material) winter warm summer cool, and synthetic agate changes with the external temperature changes, it is hot in the heat, it is cool in the cold.
9. The most striking difference between natural agate and counterfeit products is whether there is a concentric layered structure in the cross section. However, the whole piece of agate is easier to identify, and the cut finished product has no obvious neat pattern and is easy to admit. But in general, natural agate feels cool, the surface is coated with a layer of wax, and has a waxy luster; translucent; hardness is above Mohs grade 7, with a small knife; it is formed in a molten state Crystals, mostly spherical (such as rain stone), are particularly dense, and the surface is more delicate after grinding. It can be rubbed on the hard board for a dozen times. Generally, the agate is not hot, but the board is hot; the color is often a variety of colors. Mixed in a piece of agate, forming beautiful patterns, layers, brocade and other colorful patterns.
It is said that things are rare, and South Red Agate also justifies this. Therefore, when you choose South Red Agate, you should pay more attention to it and observe more. It is our purpose to select the true South Red Agate.
