In many jade markets, bloodstone, a natural bright red stone, has been treasured for many years. Favored by collectors and investors, the value of bloodstone has been rising all the way, and bloodstone has become one of the new favorites in the market. What followed was the proliferation of fake bloodstone, so it is very important to identify the authenticity of bloodstone!
Identification of authenticity of bloodstone
To identify bloodstone, we need to look at the red color of "blood" first, preferably fresh, condensed and thick. In addition, the spread of bloodstone is also an important basis for identifying bloodstone. What is a bloodstone? What is the ground of bloodstone? The stone is dyed red. The ground of bloodstone is pure, translucent and brightly colored. For the identification of bloodstone, the "blood color" of natural bloodstone overflows and is bright red and smart, while the fake bloodstone is stiff and dull.
The identification of bloodstone can be based not only on its basic characteristics, but also on its fraudulent means. At present, there are several fake methods of bloodstone in the market, such as mosaic method, impregnation method, slice patch method and patch method. Although the fake means of bloodstone are escalating, there is a difference between fake bloodstone and real bloodstone after all. Whether it is the surface or the internal structure of the stone, the difference can be found by naked eye observation or with the help of instruments, and the true and false bloodstone can be identified.
Classification and differentiation of bloodstone
1, look at the color
The color of bloodstone can be roughly divided into bright red, bright red and dark red. Among them, bright red is the top grade, followed by bright red and dark red is the worst.
2. Look at the shape of blood
The blood forms of bloodstone can be divided into blood clots, blood stains, cloud blood and punctate blood in turn. Generally speaking, the bloodstone with unique blood shape often doubles its value because of its uniqueness.
3. Look at the blood volume
Blood volume refers to the percentage of chicken blood and finished stone. More than 30% are high-grade products, more than 50% are treasures, and more than 70% are fine products. But if the blood color is not beautiful or the base material is not good, its grade will still drop sharply. Take Yin Shi as an example, besides blood volume, it is divided into six kinds of blood from six sides to one side. Six sides are top grade, four or five sides are authentic, three or two sides are medium grade, and one side is the worst.
Step 4 look at the concentration
Concentration refers to the aggregation and dispersion degree of chicken blood, which is divided into three levels: thick blood, clear blood and scattered blood. Among them, thick blood is the most expensive, clear blood is the second, scattered blood is diluted like chicken blood, and the quality is the worst.
