鸡血石，中国“四大国石”。同寿山石、青田石、巴林石并列。鸡血石与田黄石、青田灯光冻石被誉为印石三宝，主要用作为印章或是工艺雕刻品材料。

鸡血石是由“地”和“血”两部组成。一般认为“血”的矿物成分主要是辰砂。“地“的成分，如昌化鸡血石。

 

 

鸡血石的形成是因朱砂（硫化汞）渗透到高岭石中，地开石之中缓慢而成，形成时间可与化石同等，这样两者交融，共生一体的天然宝石，在国内外是极为罕见的一种。也有的鸡血石是含有‘橄榄石’辉石凝结而成。

鸡血的成份是硫化汞，石质则为地开石或高岭石，硬度为2—3度。石中时常带有水银斑及少量的石英颗粒突起于石表面。鸡血中除主要成份为硫化汞外，还含有少量的致色元素铁、钛。

鸡血石含有辰砂、(朱砂)、石英、方解石、辉锑矿、地开石、高岭石、白云石等矿物，且大部分含硫化汞等多种成份的硫化物以及硅酸盐矿物。产地不同，质地成分也不同，但都离不开硫化汞成分，也有‘氧化铁’的橄榄石成分。

昌化鸡血石可分为冻地、软地、刚地和硬地四大类。冻地鸡血石为玻璃冻、羊脂冻、牛角冻、桃花冻等，微透明或半透明，硬度在2—3级。软地鸡血石的硬度为2—4级，刚地鸡血石是高岭石、明矾石岩经后期硅化的产物，硬度在4—7级。而此件鸡血石为（昌化刚地）硬度在4—6级。

Soapstone, China's "four major national stones". Tongshou Mountain Stone, Qingtian Stone and Bahrain Stone are juxtaposed. Heliotrope, Tian Huangshi, Qingtian lighting frozen stone are known as the three treasures of Indian stone, mainly used as seals or craft carving materials.

 

Soapstone is composed of two parts: "ground" and "blood". It is generally believed that the mineral component of "blood" is mainly cinnabar. The ingredients of "ground", such as Changhua Soapstone.

The formation of heliotrope is due to the slow penetration of cinnabar (mercury sulfide) into kaolinite and dickite, and the formation time can be the same as that of fossils. In this way, the natural gemstones that blend and coexist are extremely rare at home and abroad. Kind of. Some heliotrope is condensed from pyroxene containing olivine.

 

The composition of chicken blood is mercury sulfide, the stone is dickite or kaolinite, and the hardness is 2-3 degrees. The stone often contains mercury spots and a small amount of quartz particles protruding from the stone surface. In addition to the main component of mercury sulfide in chicken blood, it also contains a small amount of coloring elements iron and titanium.

 

Soapstone contains chensha, (cinnabar), quartz, calcite, antimony ore, dickite, kaolinite, dolomite and other minerals, and most of them contain mercury sulfide and other sulfide and silicate minerals. The origin is different, the texture composition is also different, but they are inseparable from the mercury sulfide component, and there is also the olivine component of iron oxide.

 

Changhua Chicken Blood Stone can be divided into four categories: frozen ground, soft ground, hard ground and hard ground. Frozen chicken bloodstones are glass jelly, sheep fat jelly, horn horn jelly, peach flower jelly, etc., slightly transparent or translucent, and the hardness is 2-3. The hardness of soft ground bloodstone is 2-4, and the gangue bloodstone is the product of later silicification of kaolinite and alumite rock, and the hardness is 4-7. And this piece of bloodstone has (Changhua Gangdi) hardness of 4-6.
