Fake chicken bloodstones can be distinguished by the chicken blood pattern, texture, weight, etc.:

1. Fake chicken blood stones have no silver spots, uneven color depth, and different line thicknesses. The pattern is unnatural and the arrangement does not conform to the rules of chicken blood. It is easy to distinguish with the naked eye.

2. The texture of fake soapstone is faked with plastic compounds. It has no stone feel at all, and there is no stone dust when carved with a knife. Some people even sliced ??the bloodstone into slices, pasted it on rough stones, and then used caulking glue and stone powder to bond it. Coherent and not difficult to see through.

3. Fake chicken blood is lighter in weight and can be tested using several steps.

(1) Use emery cloth to grind it finely. The real chicken blood stone will be in the form of stone powder with cinnabar red, but the fossil stone will not.

(2) Use a knife to carve the fake chicken bloodstone into plastic curled stone chips that can be felt.

(3) When burned with fire, fake soapstone will have a burnt glue smell, but real soapstone will not.

(4) It is heavy when measured by hand. Fake bloodstone feels lighter due to its different texture.

When evaluating chicken blood stone, first look at the red color of the "blood", which is better for its freshness, coagulation and thickness. Fresh means red like dripping blood; condensed means gathering but not dispersing; thick means having thickness and layers that penetrate deeply into the stone layer. In addition, the location of the bloodstone is also an important basis for judging the bloodstone. The ground is what kind of stone is dyed red.

The top grade of bloodstone is pure, translucent, without nails and the bright red color of blood complements each other. Soapstone samples can be divided into square, rectangular, oval, round, and deformed shapes. The appropriate size is roughly 5-2 cm in diameter.

Soapstone has a fine texture, toughness, and tight structure that will not fall apart under a knife. Good bloodstones are not carved, and are best used for seals. Any chicken blood that is added with carvings is generally used to cover up flaws and is not expensive.

Extended information:

Soapstone is a cinnabar (mercuric sulfide) that penetrates into kaolinite and is slowly formed into the ground stone. In this way, the two blend and become one. The natural gemstone is extremely rare at home and abroad. Some bloodstones also contain 'olivine' pyroxene agglomerates.

The composition of chicken blood is mercury sulfide, and the stone is dikaiite or kaolinite, with a hardness of 2-3 degrees. There are often mercury spots in the stone and a small amount of quartz particles protruding from the surface of the stone. In addition to the main component of mercury sulfide, chicken blood also contains small amounts of color-causing elements iron and titanium, which are dark dyes.

The main reason why chicken blood shows different red colors is its content. If the content is high, the blood will be dark red. In addition, chicken bloodstone also contains different photosensitive elements such as selenium and tellurium. This is also the main reason why chicken blood fades or changes color (appears dark red) under light and heat.
