Frequently asked questions about Lab Diamonds VS. Mined Diamonds
What Is A Lab Grown Diamond?
Lab-created diamonds are grown in highly-controlled laboratory conditions that reproduce the Earth’s natural growing environment. These diamonds have the same chemical composition, crystal structure, optical and physical properties of diamonds found in nature. They show the same fire, scintillation and sparkle as mined diamonds. Lab grown diamonds are categorized as either high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) diamonds, depending on the method of their production.
Are lab diamonds as strong as natural diamonds?
Lab diamonds are as strong and as hard as natural diamonds, both scoring a 10 on the Mohs scale of hardness.
Can a gemologist tell if a diamond is lab-created?
For even professional gemologists, it’s often not possible to tell the difference between a natural and a lab-created diamond with the naked eye. But with specialized equipment, a gemologist is able to identify a lab-created diamond.
Will lab diamonds pass a diamond tester?
Yes. Lab diamonds are real diamonds, made from pure crystallized carbon, and will pass the diamond testers.
Are lab-grown diamonds GIA certified?
Lab diamonds are graded on the same scale of Cut, Clarity, Color and Carat weight as natural diamonds. The GIA does certify lab-grown diamonds, however, since they have just started, they aren’t that many of them. I recommend IGI certifications for lab diamonds, as they also give specific grades for Color and Clarity.
Bottom Line: Do What Feels Right For You
Nature-formed and lab-created diamonds are chemically exactly the same. If you decide to purchase any of those diamonds, I would recommend seeing it in person before you buy — and picking the stone that speaks to you personally.
