A lab-grown diamond is a diamond that is created in a laboratory setting using advanced technological processes. The main difference between the a lab grown diamond and a natural diamond is their origin: natural diamonds are mined from the earth, while lab-grown diamonds are created in a controlled environment.


Lab grown diamonds are chemically, physically, and optically identical to natural diamonds.

Lab-grown diamonds are made of the same material as natural diamonds: pure carbon that has been subjected to extremely high pressure and temperature. They have the same atomic structure, the same optical and physical properties, and the same hardness and durability as natural diamonds. They are also graded using the same 4Cs (cut, clarity, color, and carat weight) as natural diamonds.

In short, lab-grown diamonds are real diamonds in every sense of the word. They are just created using a different method than natural diamonds.

Why Choose Lab Grown Diamonds?

Quality - Lab diamonds have the same physical, chemical and optical properties as a mined diamond.
