The term ‘synthetic’ for ‘lab grown diamonds’ is immensely confusing and deceiving specially for consumers. Lab grown diamonds are 100% diamonds and should not be misrepresented to consumers. Cubic Zirconia and synthetic moissanite are considered synthetic or artificial because they are meant to imitate a diamond. 
PDC Diamonds are 100% genuine diamonds that are certified by independent grading labs. Grown using advanced technology in labs which recreates conditions from under the earth, PDC rough grown diamonds are cut and polished using the same tools and techniques as used for earth-mined diamonds.
