和田玉，“中国四大名玉”之一（其三为陕西蓝田玉、辽宁岫玉和河南独山玉）。传统狭义范畴特指*疆新**和田地区出产的玉石，以和田“子料”为代表闻名于世；广义的和田玉指软玉（真玉）。和田玉虽然因*疆新**和田而命名，但其本身不是地域概念，并非特指*疆新**和田地区出产的玉，而是一类产品的名称。中国把透闪石成份占98%以上的石头都命名为和田玉，都在国标范围内。
秦始皇统一中国的时候，和田玉因产于昆仑山被称为“昆山之玉”，以后又因位于“于阗国”境内而被称为“于阗玉”。直到清光绪九年（1883年）设立和田直隶州时，才被正式命名为“和田玉”。
和田玉中的名品，是珍藏于陕西历史博物馆的西汉国宝级*物文**“皇后之玺”，其质地为*疆新**和田羊脂玉，是迄今唯一的汉代皇后玉玺，为首批禁止出国（境）展览*物文** 。2008年北京奥运会会徽徽宝“中国印”，也是采用*疆新**和田玉作为材料。
和田玉属镁质大理岩与中酸性岩浆岩接触交代而形成的变质岩，内含透闪石、角闪石、阳起石等多矿物集合体，化学成分是含水的钙镁硅酸盐，化学式为Ca2(Mg,Fe2+)5[Si8O22](OH)2，密度为2.95—3.17，摩氏硬度在6.0—6.5之间。
藏品介绍
中文名称：和田玉龙凤佩
英文名称：Hetian jade dragon and Phoenix pendant
类别：玉器
规格：一件
品相：美品
螭是古代神话传说中的一种龙。螭龙寓意美好，吉祥，招财，也寓意男女的感情。《汉书·司马相如传上》：“于是蛟龙赤螭。”颜师古注：“文颖曰：‘龙子为螭。’张揖曰：‘赤螭，雌龙也。’如淳曰：‘蠄，山神也。’”《广雅》云：“有角曰虬，无角曰螭。”
按常理，有角的为虬龙，可以看都龙首脑后，有两y字形的角，实际上这就是虬龙，现在在文玩市场经常被误称为螭龙佩，而这是一对不折不扣的虬龙，两虬龙以背相对，头顶上为一雷纹玉璧，左右刻的各一只凤纹，以首相对，玉璧边缘下刻如意纹，可以看到整个玉佩的轮廓就形似一个如意头，上缘蝙蝠纹，而玉璧为礼天之器，寓意着洪福齐天，龙凤呈祥，如意吉祥，寓意吉祥，雕工精湛，且品相完美十分难得。
文化
文化：油润细腻的质地，“色如截脂”的净白，“常如肥物所染”的光泽，符合中国传统文化含蓄的审美观念，不张扬，不艳丽，不耀眼，用一种“精光内蕴”的美，吸引了中国人几千年。羊脂玉的美丽之中有一种神秘的魅力，多少人为之痴狂陶醉，千金散尽亦不悔。
古人关于玉有“五德”、“九德”、“十一德”的种种论述，更将玉石的人文内涵提高到了一种神圣的地步。
收藏价值：自古道，“黄金有价玉无价”。这件和田龙凤佩，颜色是带有油脂光泽的白，整体油感足，入手温润，久握存温，且温度流失缓慢，经鉴定，为难得的和田玉，和田玉投资一直都被关注，一篇‘疯狂的石头’报道了和田玉十年涨幅千倍，令人咋舌，如今*疆新**本地也找不好的和田玉了，再加上政府禁止开采，形成了十玉九藏的局面，使得和田玉价格水涨船高，加上这是一件龙凤老玉佩，具有极高的收藏价值。
英文翻译：Hetian jade, "China's four famous jade" one (its three for Shaanxi Lantian jade, Liaoning xiuyu jade and Henan Dushan jade). The traditional narrow sense refers to the jade produced in Hetian, Xinjiang, which is famous for its "sub-materials". Hetian jade in the broad sense refers to nephrite (true jade). Although hetian jade is named after Xinjiang Hetian, it is not the concept of the region itself, not specifically referring to the jade produced in Xinjiang Hetian region, but the name of a class of products. In China, more than 98% of the tremolite is named hetian jade, which is within the scope of national standards.
When Qin Shi Huang unified China, hetian jade was called "jade of Kunshan" because it was produced in Kunlun Mountain. Later, it was called "Jade of Khotan" because it was located in the land of Khotan. It was not until the ninth year of The Guangxu Emperor of the Qing Dynasty (1883) when hetian Zhili Prefecture was established that it was officially named "Hetian Jade".
The famous hetian jade is the Queen's Seal, a national treasure of the Western Han Dynasty, which is stored in The Shaanxi History Museum. It is made of Xinjiang Hetian amniocentric jade. It is the only queen's seal of the Han Dynasty so far, and the first batch of cultural relics forbidden to be exhibited abroad. The Beijing 2008 Olympic Games emblem "Chinese seal", is also using xinjiang Hetian jade as material.
The metamorphic rock formed by contact metasomatism between Hetian jade magnesian marble and intermediate-acid magmatic rock contains multiple mineral aggregates such as tremolite, hornblende and actinite. The chemical composition is water-bearing calcium and magnesium silicate, the chemical formula is Ca2(Mg,Fe2+)5[Si8O22](OH)2, the density is 2.95 -- 3.17, and the Hardness is between 6.0 -- 6.5.
