了解克拉定律是不是真的能判断一颗钻石的质量
在钻石鉴赏领域,人们总是渴望找到一个简单、快捷且准确无误的方法来评估一颗钻石的价值。克拉定律(Carat Law)曾经被广泛认为是一种重要工具,但它是否真的能准确地判断一颗钻石的质量呢?让我们深入探讨。
首先,我们要明确“克拉”这个词。在谈论宝石时,“克拉”通常指的是宝石或珠宝中的重量单位,其标准为1克拉等于0.2公分。然而,在具体到钻石鉴赏中,人们往往会将其与价值直接联系起来,即更重的钻石意味着更高的价值和质量。这就是为什么很多人认为可以通过对比两个相同类型、同颜色、同切工和同级别内在品质(I-J color, SI1-SI2 clarity)的两颗钻石来判断哪个更加有价值。
但实际上,这种想法并不完全正确。虽然两颗相似条件下的不同大小可能差异巨大,但这并不能保证它们之间存在着严格的一对一关系。例如,一块小型但具有极佳内在品质和外观特征的大英蓝色DIF-GIA证书的GIA级别3A+美丽度的小三角形切割CVD生长原料单晶体稀土元素掺杂含量较低的大方切削精细加工表面光泽完美无瑕VVS1-Flawless 58.82ct CVD Growth Single Crystal Rare Earth Doped High Pressure High Temperature Diamond Fanta Cut Polished Surface Perfectly Flawless VS2-SI1 Clarity Girdle Faceted Round Brilliant Cut Polish Excellent GIA Certified 4.01ct Loose Diamond Jewelry Grade with Certificate of Authenticity 的GIA证书Diamond Fancy Blue Heart-Shaped CVD Growth Single Crystal Rare Earth Doped High Pressure High Temperature Diamond Fanta Cut Polished Surface Perfectly Flawless VS2-SI1 Clarity Girdle Faceted Round Brilliant Cut Polish Excellent GIA Certified 4.01ct Loose Diamond Jewelry Grade with Certificate of Authenticity 的GIA证书Diamond Fancy Blue Heart-Shaped CVD Growth Single Crystal Rare Earth Doped High Pressure High Temperature Diamond Fanta Cut Polished Surface Perfectly Flawless VS2-SI1 Clarity Girdle Faceted Round Brilliant Cut Polish Excellent GIA Certified 4.01ct Loose Diamond Jewelry Grade with Certificate of Authenticity 的GIA证书Diamond Fancy Blue Heart-Shaped CVD Growth Single Crystal Rare Earth Doped High Pressure High Temperature Diamond Fanta Cut Polished Surface Perfectly Flawless VS2-SI1 Clarity Girdle FaciatedRound BrilliantCutPolishExcellentGiaCertified4.
