  • Cut
  • Clarity

Considering about the hue of the gemstone, the primary hues are violet, blue, green, yellow, orange, and red. These hues together may create a secondary hue, adding a different level of glittering glamour to your gemstone. However, if your gemstone has a pure colour, then it is more valuable than a gemstone which has a colour shade.


The fourth C of the gemstones is cut, which expresses how the gemstone is faceted and styled to refract light. There are several cuts that are faceted in gemstones. Some of such cuts are: Rose cut, Barion Cut, Eight cut and old mine cut. Noteworthy to mention is the “Ceylon Cut” that was born in Ceylon, which comprises a brilliant-cut crown and a step-cut pavilion.


The clarity of the gemstone is determined by the fact that whether foreign inclusions are added to the gemstone. Such foreign inclusions could be other minerals, dust, insects, liquid or air pockets. If the gemstone you buy doesn’t have any inclusions, the value of it greatly increases.
