切工的目的是为了将宝石的光学效果发挥到最佳
任何以破坏宝石光学效果的切工都是误导

以猫眼和变色最为罕见
[IMGA]http://colorlane.com/UploadFile/2006-10/2006101121105779390.jpg[/IMGA]
[IMGA]http://colorlane.com/UploadFile/2006-10/2006101121111156058.jpg[/IMGA]
只有金绿宝石中具有猫眼效应的可以直接叫猫眼
其他具有猫眼效应的宝石 只能称为 具有猫眼效应的某某宝石
[IMGA]http://colorlane.com/UploadFile/2006-10/2006101121112815520.jpg[/IMGA]
星光宝石是有规律的
比如星光红蓝宝 天然中一般是6根线 发现过12根线的
如果不是6或12根线 必然是假的

某些宝石如果有裂隙 也会在阳光的照射下产生类似的效果
其实是裂隙将阳光折射产生的效果 有点像我们原先玩的三棱镜
[IMGA]http://colorlane.com/UploadFile/2006-10/2006101121115466032.jpg[/IMGA]
变色是最为罕见的效果
除了变石 很多宝石中偶然都会出现在常态下变色的特殊种类
比如 有在常态下三次变色的钻石
这种就属于非常罕见 非常珍贵的宝石了 价格往往是天价 |
