2008中国嘉德秋拍中一块昌化鸡血石山子摆件拍得1,792,000元，是近年来嘉德拍卖中拍价最高的一块鸡血石作品。让人不禁感叹鸡血石的价格正在向
着与其“石后”的身份相符的方向前进。清代民间就流传有“一两田黄三两金，昌化鸡血石没有价”。作为传统印章中的“印料之王”的鸡血石已成为收藏家眼中的
“上上品”。到底哪些是决定鸡血石价格高低的主要因素?收藏投资时如何选择?本刊记者采访了相关人士。
开采历史已有千年
鸡血石被称为“石后”，一因稀少，二因用处特殊。
稀少，是因为世界只有中国有，我国最早发现的鸡血石是浙江昌化玉岩山鸡血石。后来又发现了内蒙古赤峰市巴林右旗的巴林鸡血石。20世纪90年代又在陕
西、甘肃、四川、湖南、云南等地发现了鸡血石。由于现在的昌化朱砂(汞矿)已近尾声，所以出产的鸡血石产量相当有限，所以昌化鸡血石因开采历史长，存世量
少而最为珍贵。
出产于浙江省临安市浙西大峡谷源头玉岩山的昌化鸡血石，形成于7500万年前的火山活动，发现和开采已有1000多年历史。清乾隆年间所修的《浙江通
志》记载："昌化县产图章石，红点若朱砂，亦有青紫如玳瑁，良可爱玩，近则罕得矣"，由此一方面可见当时昌化鸡血石在民间的流行与影响;另一方面也从中得
知那时候就开采得差不多了。
而用处，一般用于印章和雕刻品，达官显贵的印章，尤其是国玺，以及国际之间的友谊赠品。如康熙、乾隆、咸丰、同治、宣统皇帝、慈禧太后均以鸡血石为宝
玺，毛泽东主席也曾经使用和珍藏昌化鸡血石。1784年，乾隆下江南，临安天目山禅源寺主持曾献8厘米昌化石一方，乾隆大喜，即刻"乾隆之宝"四字，并注
明"昌化鸡血石"。1972年，中日恢复邦交，周恩来总理选用昌化鸡血石作为国礼，馈赠日本田中角荣首相珍品印章一对。
鸡血石价格每年平稳增长
专家分析认为，鸡血石从古至今被人们喜欢的原因有几个：首先，鸡血石的颜色红艳如鸡血，民间一直就有用鸡血驱鬼避邪的说法;其次，鸡血石红艳似火，有
象征红红火火之意;但最主要的原因是鸡血石产量现在越来越少，精品更是十分难得。由于鸡血石矿中含有汞，国家曾经大规模采矿炼汞，现在剩余的鸡血石量就很
少。
近年来鸡血石价格的攀升在拍卖市场上体现得十分明显，2003年5月北京翰海拍卖会上一件清代鸡血石方章成交价仅为8000元，2005年12月品质
相当的一件清代鸡血石方章价格迅速涨到120000元，2007年12月，北京翰海秋季拍卖会举办了“日精月华——国石艺术”专场拍卖，一块由国家级雕刻
大师牛克思所雕的“昌化鸡血石雕楼阁山子”更是以1344万元人民币成交，创下了当时中国当代工艺品的最高价格纪录。
曾经有媒体报道，鸡血石3年涨10倍，一位做鸡血石买卖多年的老板告诉记者，这种说法有炒作之嫌，鸡血石的市场价格没有出现短时间暴涨的情形，而是比
较平缓的增长。近几年，尤以鸡血石和田黄石市场走势越来越高。一方面，鸡血石的总体产量和精品数量大不如昔，而另一方面，收藏队伍的逐渐扩大，导致其价格
逐年攀升。正是由于其资源的极缺性，有眼力和能力的收藏投资者收藏鸡血石定会有不错的回报。
鲜血淋漓价最高
有多年收藏和投资经验的鸡血石资深藏家告诉记者，收藏鸡血石主要考虑颜色、血量和硬度。首先颜色是第一位的，因为鸡血石尊鲜红者为贵，品评鸡血石，首
先是看“血”的红色，以其鲜、凝、厚为佳。鲜者红如淋漓之鲜血，凝者聚而不散，厚者指有厚度有层次深透于石层中。颜色越鲜红越艳丽则越受追捧，但是强调要
鲜，仿佛是刚流出的鸡血，那种死板呆滞的干红价格就大打折扣。其次，看血量。鸡血石讲究血量不仅要多，而且要分布集中。一般一块石头含70%的血量即被认
为上品，70%到80%之间被誉为“大红袍”，80%以上为极品鸡血石。连续片状分布的血就比较贵，线状血次之，散点血更次。最后看硬度，由于鸡血石绝大
多数是用来篆刻作印章使用的，因此硬度很重要。同等条件下，硬度越低的越利于篆刻，而且石质更细腻温润，价格自然就高。一般把硬度低于3度的鸡血石归为
软，硬度高于3度的称为硬。鸡血石里又硬又干红的品种较差，达不到收藏级别。
另外鸡血石的地也是判断鸡血石的重要依据。地就是红色染在什么样的石头上。鸡血石的地以纯净、半透明，无钉与血之鲜红色彩交相辉映者为上品。鸡血石的品样可分为方形、长方形、椭圆形、圆形、畸形，尺寸大致以5——2厘米的径边为宜。
鸡血石的质地细腻，带韧性，结构紧密，受刀不崩，是做印章的上佳材料。专家表示，好的鸡血石都不加雕琢。红色“鸡血”以外，底色尚有黑、白、黄、绿、
蓝、灰褐、紫、青等基本颜色，再加上浓淡深浅不一的各种色彩相互融合，天然浑成，不须人工雕凿，已构成一幅幅自然美丽的图案。“可以这么说，凡是加雕刻的
鸡血一般都为遮掩其疵，是不足为贵的。”
选购鸡血石毛料风险大
按质地，鸡血石一般分为冻地鸡血石、软地鸡血石、软钢板地鸡血石和硬钢板地鸡血石4大类。顾名思义，从色状上分类，有块血、条血、梅花血、浮云血等几种
类型。"块血"的分布没有规律，东生-块、西生一块，有的块石表面有一大块红色，而里面面一点红的都没有;有的恰拾相反，所以购买鸡血石毛科风险很大。"
条血"的分布相对有规律。"梅花血"则象梅被开放一样，整个石头都是星星点。"浮云血"生在宽带或条带的间接处，即象条血又象梅花血，更象天上的浮云一
样。鸡血石的颜色有鲜红、淡红、紫红、暗红等，最可贵的是带有活性的鲜红血形。
懂行收藏者偏爱昌化鸡血石
昌化鸡血石闻名于世之后，在内蒙古巴林右旗也发现了鸡血石。但是两地的鸡血石石质不同。巴林鸡血石，透明度好、质地温润、颜色更鲜嫩。如果两块刚开采
不久的昌化石和巴林石放在一起，人们都会认为巴林鸡血石的颜色更好看，所以一般不太懂行的人都会选择购买巴林鸡血石，但是巴林鸡血石有个致命弱点，它的颜
色不稳定，随着时间的推移会逐渐褪色，原来鲜红的颜色会变淡变黑，因此高端收藏者花大价钱一般不会选择巴林鸡血石。相比之下，昌化鸡血石就比较稳定，高端
的鸡血石领域，昌化鸡血石价格就远远高于巴林鸡血石。
作伪方法有4招
物一稀，作伪者就多了起来，有几种作伪的方法比较常见。
镶嵌法，采一质地较好的昌化石章，选择几面醒目的地方，分别挖出一个个深浅不一的小坑，然后用红色的流化汞涂料嵌入，待其自然阴干后，再磨光上蜡。不过，这种嵌入的鸡血(硫化汞)没有层次，同时血与昌化石的交接处色泽生硬，没有过渡。
浸渍法，取一方昌化石，在需要的地方涂上硫化汞，阴干再涂，再阴干，使其血稍有层次，然后放在透明的树脂里浸渍，务使周身浸到，拾起晾干，再用细水沙打光即成。用这种方法因树脂易老化，日久表皮会泛黄，与内部的石色不相协调;同时树脂表皮的毛孔比较粗。
切片贴皮法，用切割机把石章的六个平面分别切割出薄如纸的六面。在需要的地方涂上硫化汞。待晾干后再用热烫的办法和以胶水把原来切割下来的六个薄片按
原样贴回去，然后把薄片与胶合处的线角磨光。这样鸡血的红色看起来生在石章里面，而且自然分布。但血的层次毕竟只能停留在一个平面上。
添补法，这是在真鸡血石上，再添加硫化汞，并在添加的部分表面罩上一层极薄的树脂，磨光后即成。这类方法是在血上加血，无疑是锦上添花，价值大增。同时真中有假、假假真真。
如何鉴别
鉴别鸡血石真假，一般用眼观、手摸、雕刻或打磨就基本可以立判真伪。
1、假鸡血没有银斑，色度深浅不匀，线条粗细不一，花纹不自然，排列不符合鸡血赋存规律，肉眼细观极易区别。
2 、质地，有的鸡血石用塑胶化合物假造，完全没有石感，用刀刻也没有石屑粉。用砂布细磨，真鸡血石材会呈石粉状而有朱砂红之现象，化合物则没有;用刀雕刻，假鸡血石下刀后呈塑质之卷曲碎屑，能感觉出来;用火烧，假鸡血石会有烧焦的胶臭味，真鸡血石则不会;
3 、重量：真鸡血石的重量较沉稳，假鸡血的重量较轻浮
2008 China Jia Deqiu shot in a Changhua chicken Dan Shanzi ornaments photograph 1,792,000 yuan, in recent years, shot the highest price in the auction Guardian piece of soapstone works. People can not help but sigh Bloodstone price is moving towards its "stone" after befitting direction. Qing Dynasty folk to spread the "twelve tianhuang thirty-two gold, Bloodstone no price." As a traditional seal of the "King of printed materials," the soapstone has become the eyes of collectors, "the top grade." Which in the end is to determine the price level of the main factors Bloodstone? How to choose when collection of investment? Our reporter interviewed stakeholders.
Mining has thousands of years of history
Bloodstone is known as "post-rock", due to a rare, two due to use special.
Scarce, because the world has only China, the earliest discovered soapstone jade rock Zhejiang Changhua soapstone. Later it was found in Inner Mongolia Chifeng City Balinyouqi Bahrain Bloodstone. In the 1990s and in Shaanxi, Gansu, Sichuan, Hunan, Yunnan and other places discovered soapstone. Now that the Changhua cinnabar (mercury) is almost complete, so Bloodstone yield produced is quite limited, so long mining history because Bloodstone, survive in the world less and most precious.
Produced in Lin'an City, Zhejiang Grand Canyon West Zhejiang jade source rock of Bloodstone, formed in volcanic activity 75 million years ago, the discovery and exploitation of more than 1,000 years of history. Qingqionglongniujian the repair of "Zhejiang Annals" record: "Changhua County seal stone production, if cinnabar red spots, such as the hawksbill also bruising, lovely play good, too near the rare men", which on the one hand was visible Chang prevalence and impact of soapstone in the private sector; the other hand, from that time on mined almost the same.
The use, generally used for seals and carvings, dignitaries seal, especially the Great Seal, and the friendship between the international gifts. Such as the Kangxi and Qianlong, Xianfeng, Tongzhi, Xuantong emperor, Empress Dowager Cixi are soapstone as Bao Xi, Chairman Mao Zedong also had the use and collection Bloodstone. In 1784, Emperor Qianlong down the south, the source of Zen Temple Lin'an Tianmu has presided offer 8 cm Chang fossils party Qianlong overjoyed instantly "Qianlong Treasure" words, and marked "Bloodstone." In 1972, the Sino-Japanese rapprochement, Premier Zhou Enlai Bloodstone chosen as a national gift, gift Japanese Prime Minister Tanaka treasures Along couple.
Bloodstone prices steady annual growth
Experts believe that, since ancient times by people like soapstone for several reasons: First, heliotrope color Hongyan, such as chicken, with chicken folk have been saying evil exorcism; secondly, heliotrope Hongyan fire, symbolic Italy's booming; but the main reason is soapstone now yield less and less quality is very rare. Since soapstone ore containing mercury, mercury refining countries have large-scale mining, and now the remaining amount of soapstone rarely.
In recent years, the rising price of soapstone in the auction market - was evident, in May 2003 Beijing Hanhai auction, a Qing Dynasty Soapstone party chapter sold only 8,000 yuan, in December 2005 quality quite a Qing Dynasty Bloodstone party chapter price quickly rose to 120,000 yuan, in December 2007, Beijing Hanhai autumn auction held "Nissei Yuet Wah - national stone Art" special auction, a piece of the sculptor carved by the national cattle Marx's "Bloodstone Thai pavilion mountain child "more is 13.44 million yuan turnover, setting a record at that time the highest price of Chinese contemporary arts and crafts.
There have been media reports, heliotrope 3 years up to 10 times, do a soapstone business owner for many years, told reporters, this argument has suspected of speculation, there is no market price situation Soapstone short spikes appear, but more moderate growth. In recent years, especially in soapstone Wada Yellowstone market trend is increasing. On the one hand, the overall yield and a large number of fine soapstone not ever, but on the other hand, gradually expanding collection team, resulting in prices rising year by year. It is precisely because of the scarcity, discerning its resources and capabilities to Favorites investor favorites soapstone there will be a good return.
Blood dripping highest price
Has many years of experience in the collection and investment soapstone experienced collectors, told reporters that the main consideration Bloodstone collection color, blood and hardness. First Color is the first, because soapstone statue red by the expensive tasting Bloodstone, first look "blood" red, with its fresh, condensate, thick better. The fresh are dripping red as blood, the condensate and leave together, it refers to the thickness of the thick layered deep penetration in the stone layer. The more red the color the more beautiful the more popular these days, but stressed the need to fresh, as if just out of the chicken, the kind of rigid sluggish red prices greatly reduced. Secondly, look at the blood. Bloodstone pay attention not only to be more blood, but also the distribution of concentration. Usually a stone containing 70% of the blood is considered the top grade, known as 70% to 80% "Big Red", more than 80% of the best soapstone. Blood continuous sheet distributed to more expensive, followed by linear blood, blood scatter more times. Finally look at the hardness, since the vast majority of soapstone carving for use as a seal, so the hardness is very important. Under the same conditions, the lower the hardness of the more beneficial carving, stone and more delicate and moist, the price of natural high. Usually the hardness of less than 3 degrees soapstone classified as soft, hardness higher than 3 degrees called hard. Soapstone was hard and red varieties poor, reach collection levels.
In addition to the Bloodstone Bloodstone it is also an important basis for judgment. Red dye on the ground is what kind of stone. Soapstone ground in pure, translucent, red color of blood and no nails each other for the top grade. Bloodstone product samples can be divided into square, rectangular, oval, round, deformity, roughly the size of 5-2 cm in diameter edge is appropriate.
Bloodstone fine texture, with toughness, structure, by knife does not collapse, it is doing a good seal material. Experts said the increase is not good soapstone carving. Other than red "chicken", there are background black, white, yellow, green, blue, gray brown, purple, blue and other basic colors, coupled with various shades of shades of color are blended into muddy natural, not to be artificial carving, depicting the natural beauty constituted a pattern. "It can be said, who added carved chicken are generally cover their faults, are insufficient to expensive."
Optional soapstone wool risks
Press texture generally divided into frozen ground soapstone soapstone, soapstone soft ground, mild steel and hard steel ground to Bloodstone Bloodstone four categories. As the name suggests, from the color classification like, a block of blood, pieces of blood, blood plum, clouds of blood and other types. "Block blood" irregular distribution, East Health - block, a born West, and some have a large red stone surface, while the inside surface of a little red are not; some just pick the contrary, so the purchase is risk soapstone gross Branch Big. "Article blood" distribution is relatively regular. "Plum Blood" is like plum are open, the entire stones are the stars points. "Cloud blood" born at broadband or indirect strip, that strip as blood and blood like plum, more like clouds in the sky the same. Bloodstone colors are red, pink, purple, dark red, the most valuable is shaped bright red blood with activity.
Knowledgeable collectors prefer Bloodstone
After Bloodstone famous, also found in Inner Mongolia Balinyouqi heliotrope. However different the two of soapstone stone. Bahrain Soapstone, transparency, moist texture, the color is more fresh. If the two newly mined near Chang fossils and Balin together, people will think Bahrain Soapstone colors look better, it is generally less knowledgeable people will choose to buy Bahrain Soapstone, but Bahrain Soapstone has a fatal weakness, its color unstable over time will gradually fade, the original bright red color fades to black, so the high-end collectors generally do not choose to spend millions Bahrain Bloodstone. In contrast, Bloodstone is more stable, high-end field Bloodstone, Bloodstone Bloodstone price is much higher than Bahrain.
Fake method 4 strokes
Was a thin, fake were up more, there are several fake way more common.
Mosaic Law, a better quality of mining Chang fossils chapter, select a few faces conspicuous places, one shades were dug pits, then embed streaming red mercury paint, let it dry naturally after, regrinding light wax. However, this embedded with blood (mercury sulfide) no hierarchy, while blood and Chang fossil junction color blunt, no transition.
Dipping, take one of Chang fossils, where needed mercury sulfide coated, dried and then cover, and then dried, so that blood levels slightly, and then placed in a transparent resin impregnated 务使 whole body immersed in, pick up dry , then fine polish Serve water and sediment. In this way because the resin easy to aging, long time, the skin will be yellow, stone color with the internal lack of coordination; while the relatively thick resin skin pores.
Slice skinning method, with stone cutting machine the six planes were cut out of chapter six-sided paper-thin. Where needed Apply mercury sulfide. Blanching to be dried and then used to glue the ways and cut down the six original sheet as is posted back, then line the sheet with glue at the corner finish. Such raw chicken blood red stone chapter looks inside, and natural distribution. But after all the blood level can only stay on a plane.
Fill method, which is the true heliotrope, add mercury sulfide, and added to the surface of the cover portion of a very thin layer of resin, polished Serve. Such methods are added to the blood in the blood, is undoubtedly the icing on the cake, the value increase. At the same time there is really false, false true.
How to identify
Bloodstone true and false identification, usually with sharp eyes, hands touch, engraving or grinding can basically established contractors authenticity.
1, no fake chicken silver spots, uneven color shades, lines of varying thickness, the pattern is not natural, the arrangement does not meet the chicken Preservative Law, meso easily distinguish visually.
2, texture, some soapstone with fake plastic compound, there is no sense of stone, with stone chips Daoke nor powder. Fine grinding with emery cloth, really Bloodstone powdered stone material will be presented and there is the phenomenon of red cinnabar, the compound is not; carving knife, the knife was a fake soapstone after plastic mass of curly debris can feel it; by fire, false Bloodstone have charred plastic smell, heliotrope is not true;
3, weight: Bloodstone true weight more sedate, lighter weight fake chicken floating
