What’s the Difference Between Lab-Grown Diamonds and Natural Diamonds?

Lab-grown diamonds and natural diamonds are more similar than they are different. Lab-grown diamonds and natural diamonds have the exact same chemical structure, physical properties, and optical properties. They’re equally durable, strong, and beautiful. The main difference between lab-grown diamonds and natural diamonds is how they’re made. Lab-grown diamonds are made in a lab by scientists, while natural diamonds form in nature.

Lab-Grown Diamond FAQs

Q: Are lab-grown diamonds real diamonds?
A: Yes, lab-grown diamonds are real diamonds that are created in a lab by scientists, rather than in the earth by nature.
Q: How are lab-grown diamonds made?
A: There are two methods used to make lab-grown diamonds: chemical vapor deposition and high pressure high temperature. The high pressure high temperature (HPHT) method requires placing a tiny diamond seed into carbon, then exposing it to immense pressure and heat, causing a larger diamond to form around the seed. This mimics how diamonds form naturally in the earth. The chemical vapor deposition (CVD) method involves placing a tiny diamond seed into a heated chamber filled with carbon-rich gas, then exposing it to ionization technology, which is similar to the technology used in microwaves. This causes carbon to stick to the seed and create a larger diamond around it.
Q: Do lab-grown diamonds look different from mined diamonds?
A: Lab-grown diamonds have the same optical properties as natural diamonds, so you can’t tell the difference between them just by looking at them. Even an expert gemologist can’t tell a lab-grown diamond apart from a natural diamond with the naked eye.
Q: Are lab-grown diamonds the same thing as diamond simulants?
A: No, lab-grown diamonds are not diamond simulants. A diamond simulant is something that looks like a diamond, but is not a diamond. Since lab-grown diamonds are real diamonds with the same physical, chemical, and optical properties as diamonds, they don’t fall into the diamond simulant category. Examples of diamond simulants include gemstones like moissanite and cubic zirconia.
Q: Are lab-grown diamonds graded by the GIA or other grading labs?
A: Yes, lab-grown diamonds are graded by grading labs. Two grading labs that commonly grade lab-grown diamonds are the Gemological Institute of America (GIA) and the International Gemological Institute (IGI).
