Determining Black Jade Value

Is California black jade valuable? The value of colored stones is typically determined by a combination of its color, clarity, cut, and carat weight. This is no different when determining what black jade is worth. These guidelines will help you choose jade stones for your collection.

After polishing, black jade displays a bright and glassy luster.

  • Black Jade Cut

An opaque stone, nephrite jade is most frequently shaped into cabochons and beads. Thanks to its durability, black jade is also frequently carved into ornamental figures.

  • Black Jade Carat
