  • VVS1 and VVS2 (Very slightly internally included)
  • SI1, SI2, SI3 (slightly included flaw)
  • I1, I2, I3 (flaw can be seen without magnifying glass aid)

Determining Diamond Carat Weight

All the gemstones are measured in weight with the help of Carat (Ct). Consequently, the carat weight also increases with size and diameter, and the prices of diamond levels up as well.

According to a rough estimation, the cost becomes double with the increment of a carat and dimension. Though 200 milligrams lie in 1 carat, the price correlates to other 4Cs as well, especially the cut and shape of the gem.
