Lab Diamonds vs. Natural Diamonds

We get asked daily; What is the difference between lab diamonds and natural diamond jewelry?

Below is a side by side comparison of the two stones.

LAB GROWN DIAMONDS

  • Chemical Composition: Carbon
  • Hardness: 10 on the Mohs Scale
  • Refractive Index: 2.417 - 2.419
  • Ethically Sourced
  • Relatively Affordable

NATURAL DIAMONDS

  • Chemical Composition: Carbon
  • Hardness: 10 on the Mohs Scale
  • Refractive Index: 2.417 - 2.419
  • Environmental Impact from Mining
  • Higher price point

Lab-grown diamonds and natural diamonds are completely identical to one another. When shopping for lab grown diamonds, you receive the same exact brilliance, hardness and chemical composition that you would get when purchasing natural diamonds but at a fraction of the cost.

-

The only difference between lab-grown and natural diamonds is their origin. Natural diamonds form deep beneath the earth's surface over billions of years, while lab diamonds are created in controlled environments using advanced technology that replicates those same natural conditions. Both result in pure carbon crystals with identical structure—meaning even experienced jewelers cannot tell them apart without specialized equipment. Your lab-grown diamond will pass every standard diamond test and deliver the same lasting beauty.

-

Lab-grown diamonds offer exceptional value without any compromise on quality. Because they can be produced more efficiently than mining diamonds from the earth, you can afford a larger carat size, higher clarity grade, or better color within the same budget. This means you get more sparkle, more presence, and more of exactly what you want in a diamond—all while making a choice that's easier on your wallet and kinder to the environment.
