藏品描述展示

猫眼石常被人们称为“高贵的宝石”。它和变石一起属于世界五大珍贵高档宝石之一。猫眼石主要产于气成热液型矿床和伟晶岩岩脉中。世界上最著名的猫眼石产地为斯里兰卡西南部的特拉纳布拉和高尔等地,巴西和俄罗斯等国也发现有猫眼石,但是非常稀少。
的猫眼石眼线应该较为狭窄,界线清晰,并显活光,并且要位于宝石的正中央。关于眼线的颜色,有人喜欢银白的额色,而有人则偏爱金黄色,而绿色和蓝白色的线较为受冷落。体色呈不透明的灰色者,常常有蓝色或蓝灰色的眼线。不过,无论什么颜色,重要的是眼线必须与背景形成对照,要显得干净利落。眼要能张很大,越大越好,而合起来时就要锐利。
 
鉴定张老师:
  单光照射
  真猫眼两边颜色不同
  国际珠宝市场上,一般从颜色、色带形状、重量、净度四个方面确定猫眼的价值,颜色纯度高、饱和度高且色质均匀者为上乘,色带(即猫眼效应丝状体)越明显、越规整且宽度适中者,价格越高。
  鉴别猫眼的方法是研究宝石中央的褐黄色的“猫眼”色带,天然猫眼的绢丝状包体有的是金红石,有的是空管,形状清晰,管状包体细长而且密集,所以猫眼效应特别明显,就是在较弱的光源下也十分清晰。
  如果用单光源从猫眼石侧面照射,猫眼石两侧的颜色明显不同:从右边照猫眼石时,右侧为蜜黄色,左侧呈乳白色;从左侧照射时,其颜色正好相反。
玻璃、石英制造的人工猫眼,在宝石的弧形顶端会同时出现几条亮带,而非一条,而天然猫眼石却只有一条;用放大镜观察人工猫眼石的两侧,可见六边形蜂窝状结构。
猫眼石是珠宝中稀有而名贵的品种,它同样拥有着猫眼效应,其原理和虎睛石基本相同。猫眼石是一种金绿宝石的变种,虽然很多宝石都具备猫眼效应,但是只有具备猫眼效应的金绿宝石才能被称为猫眼石,而其它具有猫眼效应的宝石,必须在“猫眼”二字之前加上宝石的名称。
虽然自然界中具备猫眼效应的宝石很多,但是都远不如金绿宝石猫眼来得珍贵。世界上最著名的猫眼产地是斯里兰卡。

Cat's eye stone is often referred to as "noble gems." It is one of the five precious high-grade gems in the world together with the stone change. Cat's eye stone is mainly produced in gas-forming hydrothermal deposits and pegmatite veins. The world's most famous opal is originating in places such as Tranber and Gore in southwestern Sri Lanka, with cat's eye found in countries such as Brazil and Russia, but scarce.
The cat's eye eyeliner should be relatively narrow, clear boundaries, and live light, and to be located in the middle of the gem. About the color of the eyeliner, some people prefer the silver color, while others prefer the golden color, while the green and blue-white color lines are more neglected. Body color was opaque gray, often with blue or blue-gray eyeliner. However, no matter what color, it is important that the eyeliner must be in contrast with the background to be neat and tidy. The eye can be a large Zhang, the bigger the better, but when combined will be sharp.
 
Identification Zhang teacher:
Single light irradiation
True cat eyes on both sides of different colors
International jewelry market, generally from the color, ribbon shape, weight, clarity of the value of the cat's eye in four areas, the color of high purity, high saturation and color quality are excellent, ribbons (cat's eye effect filaments) The more obvious, more regular and moderate width, the higher the price.
The method of distinguishing the cat's eye is to study the brown-yellow "cat's eye" ribbon in the center of the gemstone. The cat's eye effect is particularly obvious when the natural cat's eye silk-like inclusions are made of rutile, empty tubes, clear shapes and long and dense tubular inclusions, It is also very clear under the weaker light source.
When illuminated with a single source from the side of a cat's eye, the opal has a markedly different color on either side: when cat's eye is stoned from the right the honey is yellow on the right and milky white on the left; the opposite color when illuminated from the left.
Artificial cat's eye made of glass and quartz can show several bright bands at the top of the arc of the gem instead of one, while the natural cat's eye stone has only one piece. When magnifying glass is used to observe both sides of artificial opal, hexagonal honeycomb structure.
Cat's eye stone is a rare and precious jewelry species, it also has a cat's eye effect, the principle and tiger eye stone is basically the same. Opal is a golden emerald variety, although many gems have a cat's eye effect, but only the emerald with cat's eye effect can be called cat's eye stone, and other cat's eye effect with precious stones, must be in the "cat's eye" word Add the name of the gem before.
Although there are many precious stones in nature with cat's eye effect, they are far less precious than golden emerald cat's eye. The world's most famous cat's eye origin is Sri Lanka.
