大部分石陨石都是球粒陨石，球粒陨石母天体是一些细小的小行星，化学成分类似于45亿年前尚未分化的太阳星云，它们的体积不足以出现熔融和地质分化，因此没有遭遇过母天体的熔融或地质分异，结构没有发生过改变。

陨石是来自地球以外太阳系其他天体的碎片，绝大多数来自位于火星和木星之间的小行星，少数来自月球和火星。陨石根据其内部的铁镍金属含量高低通常分为三大类：石陨石、铁陨石、石铁陨石。而橄榄陨石是石铁陨石中的最稀有最珍贵的一种，全球发现量不到1%左右。

藏品介绍

中文名称：肯尼亚橄榄石陨石

英文名称：The Kenyan olivine meteorite

规格：一块（16*13*0.5CM）

重量：304.7克

类别：杂项

品相：美品(做防锈处理)

这块石陨石外形端正，质感强，比重高，容易收藏保存，陨石历来都是吉祥石，天外来物，“石来运转”寓意美好。这块陨石美若星河金，黑，银相间，错落有致，形成了非常美妙的结构，是由于陨石在大气层摩擦产生极大的高温，将陨石内的物质提纯，达到了宝石一样的美丽质感。

陨石是太阳系的“考古”标本，根据对陨石中铀、钍、钾等元素的同位素组成的测定，可以推算出：太阳系元素的年龄为54±4亿年，元素形成后至太阳星云凝聚之间的“间隔年龄” 为1—3亿年，太阳星云开始凝聚是在距今47 亿年前，太阳系中各类陨石凝结的年龄大约是 45—46亿 年，这也可以作为太阳系各行星形成的年龄。由此可见，研究陨石对太阳系演化的年代学的研究有多么重要的意义。 陨石在太阳系茫茫空间运行过程中，有可能由于受到碰撞而破碎，碎片直接暴露在宇宙射线之下，会形成许多种宇宙成因核素。对陨石中各种宇宙成因核素的研究， 可以为我们探讨银河系宇宙射线的成分、能谱，认识宇宙线的长期变化规律，弄清高能核反应的特点，故而，陨石又被称作宇宙空间的天然“探测器”。

非洲肯尼亚气候炎热干燥，有利于陨石的保存，因此发现于地表的橄榄陨石品相更好，品质要明显好于地下发掘出来的陨石（地下发掘的陨石因常年埋藏在土壤中，土壤中的水分长期侵蚀陨石，导致陨石氧化严重）。这也是国内判断肯尼亚橄榄陨石价值的重要标准。国内通常用“地表货”、“地下货”来区分。

地表货最明显的特征就是锈层薄，表面能看到裸露的橄榄石晶体，陨石内部橄榄石晶体呈金黄色。

品质好的肯尼亚橄榄陨石切开后可以看见内部的橄榄石晶体色泽金黄，让人赏心悦目。

素来陨石就被视为吉祥之石：有时来运转之意，更有天降时运的好兆头，在这个人民币快速贬值的时代，商人更愿意投资稀有品，正所谓千金易得，一宝难求，目前人们追求陨石更胜过钻石，更有甚者拿陨石泡茶，来调节人体磁场，达到健身养生的目的。这一块陨石外观品相极好，做个底座就能当摆件，观赏价值以及收藏价值极高。

印章，亦称图章，用作印于文件上表示鉴定或签署的文具，一般印章都会先沾上颜料再印上，不沾颜料、印上平面后会呈现凹凸的称为钢印，有些是印于蜡或火漆上、信封上的蜡印。制作材质有 金属、木头、石头、玉石等。

和田黄玉，新疆和田玉的四大主色玉之一。晶莹剔透、柔和如脂，质地细腻、滋润，以色黄正而骄，润如脂者使其身价不菲，它稀有罕见，是玉中的珍品，产量很少，可与羊脂玉相媲美。

此款为篆书卫长君款，篆刻苍劲有力，十分精美。

卫长君，原名卫长子，后改表字为长君 。河东平阳（今山西临汾）人。西汉名将卫青、卫思后卫子夫的长兄。官职为侍中。

卫长君大概于元光年间去世。后来，汉武帝拜卫青为将军，出击匈奴。

卫长君出生于汉文帝末年。身世寒微，其家号卫氏，在当时的平阳侯封邑境内。其父早卒无载，母亲冠以夫姓称卫媪，曾为平阳侯家僮，一说侯妾。

卫长君是家中长兄，下有三个妹妹三个弟弟，分别是卫君孺、卫少儿、卫子夫，卫青、卫步、卫广。

汉武帝建元二年，卫长君的妹妹卫子夫在平阳公主府被武帝看中，带回宫中。建元三年，卫子夫复幸有孕，尊宠日隆，陈皇后嫉妒卫子夫，其母馆陶公主绑架了卫青。卫青获救后，汉武帝召子夫的哥哥卫长君 、弟弟卫青作了侍中。到卫家兄弟都显贵时，几天里赏赐达千金之多。卫君孺嫁给了太仆公孙贺作妻子。卫少儿原先跟陈掌私通，皇上召见陈掌让他当官。子夫作了皇帝夫人。卫青当上了太中大夫 。而后十年，卫子夫受到大幸，有宠，育有三女 [5] 。元朔元年生男孩刘据，遂被立为皇后 。

在此之前卫长君已去世，乃以卫青为将军，而卫青征伐匈奴立下大功，封为长平侯。而后卫氏枝属五人为侯，贵震天下。

篆体，汉字古代书体之一，也叫篆书。是对古文字的统称。“篆者，传也，传其物理，施之无穷。”古人认为篆书为仓颉所造，其实是不可信的。一种文字的产生是要经过一个较长的酝酿发展过程的，不可能有一个人在短时期能完成。广义的篆体包括隶书以前的所有书体以及延属，如金文、石鼓文、六国古文、小篆、缪篆、叠篆等。狭义主要指“大篆”和“小篆”。篆书字划圆转，结构依六书之义，故唐孙过庭谓：“篆尚婉而通”。

印章主要图案为一立体的狮子，我们称为狮钮，这枚狮钮印章在自然光线出现漫反射情况，底光柔和，极其温润，狮子的刻花工艺简单明了，符合汉代刀工的特征，俗称为汉八刀，狮子回头相望，寓意好（狮）事在后头。

底部阴刻篆体精美，玉质细腻，印章小巧便于携带收藏，黄玉温润、细腻，其声若金磐之余音，绝而复起残声远沉，徐徐方尽。他最具中国文化，像一位世家王子，翩然而处变不惊。他成熟内敛，不事声张，谦虚和顺的外表之下，充满生气却又那么坚定不移。无论在秦歌汉赋还是唐诗宋词中，他都那般光艳照人，从未在光阴更替中失色。

黄玉基质为白玉，因长期受地表水中氧化铁渗滤在缝隙中形成黄色调。根据色度

变化定名为：蜜蜡黄、栗色黄、秋葵黄、黄花黄、鸡蛋黄等。古人以“黄侔蒸梨”者为最好。色度浓重的蜜蜡黄、栗色黄极罕见，其经济价值可抵羊脂白玉。在清代，由于黄玉为“皇”谐音，又极稀少，一度经济价值超过羊脂白玉。

黄玉硬度大，达到6.5，质地细腻，韧性强，具有典型的油脂光泽，精光内蕴。通俗地说，就是要像鸡油，油油的，糯糯的，酥酥的。

黄玉是典型的气成热液矿物，产于花岗伟晶岩、酸性火山岩的晶洞、云英岩和高温热液钨锡石英脉中。古人以“黄侔蒸梨”者最好。因含杂质而呈现出不同的黄色，由淡黄、甘黄至黄闪绿色。又可分为蜜腊黄、粟色黄、秋葵黄、黄花黄、鸡蛋黄、米色黄、黄杨黄等。其中色如新剥熟栗色者为贵，甘黄玉、焦黄者次之。黄玉的结晶颗粒普遍都比较小，但是能量温暖、厚实、穿透力强，对应太阳轮，是十分平和稳重的玉石，能带来温暖和勇气。

黄色似金，大地的颜色，火焰的光彩，被佛教和帝王们视为神圣的颜色。黄玉除独有的庄严华贵的色泽外，在我国古代，黄色代表王者之色，并为宗教所用，有崇高、华贵、威严、神秘之感。黄色被认为是阳光和大地之色。如后汉刘熙的《释名》：“黄，晃也，犹晃晃，像日光色也。”东汉的经学家、文字学家许慎《说文》：“黄，土之色也。”象征着能使万物生长的阳光和土地，受到人们的崇尚。黄色与黄金同色，又让我们想到“古来金玉系良缘”之说，黄玉似乎融合了金与玉的天性，使其具有很高的观赏性和更深的文化底蕴。

这件玉印章出自汉代的名人，落款卫长君，为汉代大将军，曾电视剧中也有提及卫青将军的光辉事迹，可谓是见证名人事迹的古玩珍品，对于汉代历史研究有着巨大的价值，就印章本身玉质细腻温润，属于上等的和田黄玉，以当时的名匠所雕刻，具有极高的收藏价值。

英文翻译：Most of the stone meteorites are chondritic meteorites, the parent bodies of chondritic meteorites are some small asteroids, the chemical composition is similar to the undifferentiated solar nebula 4.5 billion years ago, their volume is not enough to appear melting and geological differentiation, so they have not encountered the melting or geological differentiation of the parent bodies, the structure has not changed.

Meteorites are pieces of debris from other bodies in the solar system outside Earth. The vast majority come from asteroids between Mars and Jupiter. A few come from the moon and Mars. Meteorites are usually divided into three categories according to the content of iron and nickel in their interior: stone meteorites, iron meteorites and stone meteorites. The Olivine meteorite is one of the rarest and most precious meteorites, with less than 1% found globally.

The collection is introduced

Kenyan olivine meteorite

English name: The Kenyan November 11, 2013

Specification: One piece (16*13* 0.5cm)

Weight: 304.7 grams

Category: Miscellaneous

Product phase: Mepin (for anti-rust treatment)

This stone meteorite regular shape, texture strong, high specific gravity, easy to collect and preserve, meteorites have always been auspicious stone, the outside of the day, "stone to run" meaning good. This meteorite beauty if the star river gold, black, silver alternate, strewn at random, formed a very beautiful structure, is due to the meteorite in the atmosphere friction to produce a great high temperature, the meteorite inside the material purification, to achieve a gem like beautiful texture.

Meteorites are the "archaeological" specimens of the solar system, according to the meteorites uranium, thorium, potassium and other elements of the isotopic composition of measurement, can be calculated: the age of the solar system elements for 54-400 million, element to after the formation of the solar nebula cohesion between "space age" for the 1, 300 million, the solar nebula began to condense is in about 4.7 billion years ago, all types of meteorites condensation in the solar system is about 45-4.6 billion age, it also can be used as the planets in the solar system formation of the age. Thus, the study of meteorites to the evolution of the solar system chronology is of great significance. As meteorites travel through the vast space of the solar system, they may break up due to collisions, and the debris is directly exposed to cosmic rays, forming many kinds of cosmogenic nuclides. The study of all kinds of cosmogenic nuclides in meteorites can help us to explore the composition and energy spectrum of cosmic rays in the Milky Way galaxy, understand the long-term variation rules of cosmic rays, and make clear the characteristics of high-energy nuclear reactions. Therefore, meteorites are also known as the natural "detectors" of space.

The climate of Kenya in Africa is hot and dry, which is conducive to the preservation of meteorites. Therefore, the olivine meteorites found on the surface of the earth have better appearance and better quality than meteorites excavated underground (meteorites excavated underground are buried in the soil for years, and the water in the soil corrodes meteorites for a long time, resulting in serious oxidation of meteorites). This is also an important criterion for judging the value of Kenyan olivine meteorites in China. Domestic usually use "surface goods", "underground goods" to distinguish.

The most obvious feature of the surface cargo is the thin rust layer, the surface can be seen exposed peridot crystals, the meteorite inside the peridot crystals are golden.

When the good quality Kenyan olivine meteorite is cut open, the olivine crystals inside can be seen to be golden in color, which is very pleasing to the eye.

Have meteorites is considered auspicious rock: sometimes for work, more of heaven to be a good one million head, in this era of rapid renminbi devaluation, businessmen are more willing to invest a rare product, is the so-called daughter comes easily, a treasure is hard to find, at present people pursuit of meteorites more than diamonds, moreover meteorites make tea, magnetic field to adjust the human body, achieve the goal of fitness regimen. These two meteorites look very good, do a base can be a decoration, ornamental value and collection value is very high.

Seals, also known as seals, are used as stationery for marking identification or signature on documents. Generally, seals are stained with paint before being printed. If the seals are not coated with paint, they will appear concave and convex after being printed on the flat surface. The production materials are metal, wood, stone, jade and so on.

Hetian topaz is one of the four main colors of Hetian jade in Xinjiang. Glittering and translucent get clear, soft be like fat, quality of a material is exquisite, moisten, with lubricious yellow and arrogant, embellish be like fat person make its value expensive, it is rare rare, it is the treasure in jade, output is very few, can compare with amniotic jade.

Seal script, one of the ancient Chinese characters, also known as seal script. It is a general term for ancient Chinese characters. "Seal the seal, preach also, preach its physics, the infinite." The ancient people think seal script is made by Cangjie, actually it is not credible. The production of a language has to go through a long process of gestation and development. It is impossible for a person to complete it in a short period of time. The broad seal style includes all the calligraphic styles and genera before the official script, such as the golden script, the Stone drum script, the ancient script of the six states, the small seal script, the Miushuan, and the overlapping seal script, etc. Narrow sense mainly refers to "Big Seal character" and "Small seal character". Seal character delimits circle to turn, the structure depends on the meaning of six characters, so Tang Sun Guo Court that: "seal character wan and pass".

The main design of the seal is a three-dimensional lion, which is called lion button seal. This lion button seal diffuses the natural light, and the bottom light is soft and extremely warm. The carving process of lion is simple and clear, which conforms to the characteristics of han Dynasty's knife work, commonly known as Han Badao.

The bottom Yin carved seal body is exquisite, the jade quality is exquisite, the seal is small and easy to carry and collect, the topaz is warm and smooth, delicate, its sound is like the lingering sound of the golden rock, must rise again and the residual sound is far and deep, slowly but completely. He is the most Chinese culture, like a family prince, without fear of change. He was mature, reserved, modest and submissive, full of life and yet so firm. No matter in Qin Songs, Han Fu, Tang poetry or Song ci, he was all that gorgeous, never lost color in the course of time.

The topaz matrix is white jade, which forms yellow tone in the cracks due to long-term percolation of iron oxide in surface water. According to the chromaticity

Change gives a name for: beeswax yellow, chestnut yellow, okra yellow, yellow flower yellow, chicken yolk. The ancients to "yellow similar steamed pears" for the best. The beeswax yellow with dense chroma, chestnut yellow is very rare, its economic value can reach amniotic white jade. In the Qing Dynasty, as topaz for "emperor" harmonics, and very rare, once more than the economic value of white jade.

Topaz hardness, up to 6.5, fine texture, strong toughness, with a typical oil sheen, gloss. Colloquially, it means like chicken fat, oily, waxy, and crispy.

Topaz is a typical gas-forming hydrothermal mineral, which is produced in granite pegmatite, acid volcanic rock crystal caverns, dolomite and high-temperature hydrothermal tungstan-tin quartz veins. The ancients to "yellow similar steamed pear" the best. Due to impurity, it presents different yellow colors, from light yellow, sweet yellow to yellowish bright green. Can be divided into honeysuckle yellow, millet yellow, okra yellow, yellow flower yellow, egg yolk, cream-colored yellow, yellow boxwood. Among them the color such as new peel ripe chestnut person is expensive, sweet topaz, scorched yellow person is inferior. The crystal particles of topaz are generally small, but the energy is warm, thick and penetrating. Corresponding to the sun wheel, topaz is a very calm and stable jade, which can bring warmth and courage.

Yellow is like gold, the color of the earth, the radiance of the fire, is considered sacred by Buddhists and emperors. Topaz in addition to the unique solemn and magnificent color, in ancient China, yellow represents the color of the king, and used by the religion, there is noble, showily, dignified, mysterious feeling. Yellow is considered the color of the sun and the earth. Such as the later Han Liu Xi's "Name of Salvation" : "Yellow, sway, still wobble, like the color of the sun is also. Xu Shen, a scholar of Confucian classics and philology in the Eastern Han Dynasty, wrote in Shuo Wen: "Yellow is the color of the earth." A symbol of the growth of all things in the sun and the land, by people's worship. Yellow and gold with the same color, and let us think of the "ancient gold and jade department of good marriage" said, topaz seems to be integrated with the nature of gold and jade, so that it has a high ornamental and deeper cultural deposits.

This celebrity, from the han dynasty jade seal, dated WeiChangJun, general of han dynasty, once in also is mentioned general wei ch 'ing's glorious deeds, is a witness celebrity deeds antique treasures, and has tremendous value for han dynasty history research, seal itself, the quality of the jade stone, belong to the finest hotan topaz, at the time of the carving list, has a very high collection value.
