The 4Cs and Cubic Zirconia: When evaluating a CZ gemstone, we take into account the cut, color, clarity and carat weight of the stone.

  • Cut- There’s a variety of cuts that are used for different shapes, and the skill of the stone cutter is paramount to the final appearance of the stone.
  • Color- Color is typically the most important value-setting factor for gemstones. All gems have a preferred color or a relatively small range of preferred colors. Gemstone color can be broken down into three categories: hue, tone, and saturation. The first factor, hue, refers to the specific color of the stone.
  • Clarity- The clarity is the clearness or transparency of a stone. In genuine diamonds, clarity is determined by nature, minute mineral traces, and small crystals of imperfections that can cloud a stone.
  • Carat- Cubic Zirconia is rated by its weight or Carat Size. Gemstone sizes are frequently communicated in millimeters if the gemstone is small, typically less than one carat.


It’s a common misconception that all CZ Stones are the same. Just like Diamonds, there are a number of Quality Levels, and there is a range of Price Points for these beautiful look-alikes.
