钻石颜色图表

颜色是4C的其中一个,也是一个关键的品质因素,因为它是非常重要的钻石特征。与您所期望的相反,理想的颜色实际上完全没有颜色,被称为无色钻石。 GIA制定了钻石颜色图表,有助于在规模上对钻石进行分级。钻石颜色图表的范围从字母D到Z,今天在钻石交易中广泛使用。颜色等级D表示最稀有且最理想的无色钻石,而在另一端的Z具有淡黄色或棕色的微弱提示。从D到Z的所有钻石都被认为是白色钻石,尽管它们可能含有不同程度的颜色。在受控照明和严格观察条件下,钻石与主宝石相比色彩分级。

GIA钻石色标

选择正确的颜色等级

一旦将钻石镶嵌在钻石戒指中,并置于含有颜色的环境中(而不是钻石颜色中使用的全白色背景),颜色等级就会变得不那么明显,而且难以检测到。当J钻石镶嵌在钻石戒指中并在正常照明条件下观看时,J钻石可能看起来与D钻石钻石一样无色。

钻石的外观颜色也受安装本身颜色的影响。白色金属底座使低档钻石的颜色更加明显,而黄金使其不那么明显。您选择的钻石形状也会影响颜色等级,因为像祖母绿形状的一些形状显示更多颜色。最后,随着克拉重量的增加,颜色变得更加明显。由于尺寸的原因,使用5克拉钻石比使用2克拉钻石更容易看到J色等级。
