How are lab-grown diamonds graded?
Laboratory diamonds are graded similar to natural diamonds. During the process, diamondsare evaluated using the 4C criteria: carat, clarity, color and cut. In this blog post, we tell you all about ratings. Stay with us!
1.carat
When calculating the carat,the weight of the diamond is measuredin grams, and the carat value is determined based on this.One carat approx. It means 0.2 grams. Generally,the biggerthe carat,the bigger and more spectacular the diamond.
2.Clarity
Clarityrefers to the transparency and clarity of the mineral. Lab-grown diamonds are generally clearerthannatural diamonds, as natural diamonds oftencontaininclusions.
3.Color
The colorintensityandshade of diamonds is a key factor in their evaluation. Colorless, cooler -toned diamondshave thehighest value, while visibleyellow or other colored diamonds are priced lower. Yellowish discoloration can most often be traced back to thepresence of nitrogen. Lab-grown diamonds are usually colorless, as such diamonds contain few or no nitrogen atoms.
4.Grinding (Cut):
The cut of diamonds is one of the most important factors thatdetermine theactualvalueand beauty of a diamond. Cut includes the machining and shape of the diamond, as well as the amount andqualityof light it reflects .
Diamonds are usually made up of 57 or 58 facets(small faces) that are of different depths and angles to allow the diamond to reflect the right amount of light. If a diamond is not cut properly, it will not reflect light properly, making it less brilliant and valuable.
