什么样的和田玉才是最好的(和田玉籽料什么样的最好)
羊脂白玉是和田玉中的极品。
和田玉在古代又称软玉、昆仑玉,主要来源于昆仑山脉中,和田玉化学成分比较复杂,主要矿物成分是:透闪石。密度2.90—3.10g/cm3。硬度在6.0—6.5。和田玉的分子结构致使它的韧性非常好,加工雕琢起来可以有非常生动、细腻、传神的造型。根据和田玉的产况、产地、颜色不同,可以将和田玉有不同的分类和命名。
一、根据和田玉的产况分:山料、山流水、籽料、戈壁玉。
二、根据和田玉的产地分:和田料、青海料、俄料、韩料。
三、根据和田玉的颜色分:羊脂白玉、白玉、青白玉、青玉、黄玉、糖玉、碧玉、墨玉。
每一种分类和命名中相比较而言,和田料、籽料、羊脂白玉分别在每一种分类中占据比较重要的位置,是同类中的上品。如果同时符合这三个特性,即:新疆和田产的羊脂白玉籽料,必然会是和田玉收藏者梦寐以求的藏品。羊脂白玉要
具备如下特征:
一、颜色洁白无瑕。不可以带有其他的色调。
二、质地致密细腻。不可以有任何结晶不完全的石花出现,玉质结晶颗粒越细越好,按照行内的表述:质地要能过手电筒。
三、光泽温润如脂。和田玉的光泽看起来要像羊油,而且看的时间越长,这种感觉越明显。尤其当阳光照在羊脂玉表面时,会看到表面好像有一层油脂闪闪发亮,随时都会滴下来,如果用手去触摸,好像会粘到手指上一样。
古人形容羊脂玉的颜色为“白如截脂”、“白玉之精”。在《西游记》中,观音菩萨手里经常拿着一个羊脂白玉玉净瓶,救苦救难,普渡众生。古代,新疆向朝廷进贡的贡品多数也是羊脂白玉。由此可见,在所有的白玉品种中,品种最好、价值最高的就是羊脂白玉,如果羊脂白玉产自新疆,同时又是有漂亮皮色的籽料,一定是和田玉收藏家的最爱。市场上,也是这种和田玉的价格最高。
和田玉新坑料手镯(收于2016年)新疆和田玉最负盛名,是中国玉石群中的佼佼者,《千字文》有“金生丽水,玉出昆冈”之说,昆冈玉就是指的和田玉,其构造,古代以“填密以栗”称之,颜色非常丰富,有白色、青色、灰色、浅至深绿色、黄色至褐色、墨色等,呈油脂光泽、蜡状光泽或玻璃光泽,油脂光泽很柔和,不强不弱,让人看着舒服,摸着润美,价值较高。
根据玉质特点有“老坑料”和“新坑料”之说,“老坑料”是顶级玉石的“代名词”,容易“冒油”更耐玩。“新坑料”品质平平,往往水头过大,显清透,缺乏油润度 。
然而,关于新老料子的判定,还有一个约定俗成的看法:一件新料子成品,经过多年佩戴或把玩,醇熟老气,日益温润,便成为不折不扣的老件了,老件,也是老料。
和田玉用水测密度法最容易鉴别真假,4摄氏度的蒸馏水测量最准,用直接放在电子秤所称克数除以放在蒸馏水里所得克数的参数即为玉件密度,山料,籽料,俄料2.9-3.1,玻璃2.45-2.55。
Xinjiang Hetian Jade Most prestigious, is the leader of China's Jade Group, "Thousands of words" have "Jinsheng Lishui, Jade out of Kunduz" said, Kun Yuzhu is referring to Hetian Jade, its structure, ancient to "fill in chestnut" called, the color is very rich, white, cyan, gray, light to dark green,
Yellow to brown, ink, etc., a greasy luster, waxy luster or glass luster, grease luster is very soft, not strong or weak, let people look comfortable, touch the United States, the value is higher. According to the characteristics of Jade has "old pit material" and "new pit material", "old pit material" is the "synonym" of top jade, easy to "take oil" more resistant to play.
"New Pit material" quality is flat, often the head is too large, obvious clear, lack of oily degree.
However, on the determination of new and old materials, there is a conventional view: A new material finished products, after years of wearing or playing, alcohol cooked old, increasingly warm, it has become an unabashed older, old pieces, but also old materials. Hetian Jade Water Measurement density method is the most easy to identify true and false, 4 degrees Celsius of the most accurate of the measurement, with directly placed in the electronic scale of the number of grams divided by the number of grams obtained in distilled water is the density of jade parts, mountain materials, seed materials, Russian 2.9-3.1, glass 2.45-2.55.
