Lab grown ruby is real—it is the same gemstone as natural ruby in composition, structure, and appearance.
The difference is not what it is, but where it comes from. While natural ruby forms underground over millions of years, lab ruby is created in a controlled environment using the same materials and conditions.
The real confusion comes from how people define “real”—and that’s where most buyers get it wrong.

What Makes a Ruby “Real”?
What Makes a Ruby “Real”?
A ruby is defined by its composition, not its origin.
Scientifically, a ruby is a form of corundum (aluminum oxide) with trace chromium that gives it its red color.
If a stone has:
- The same chemical structure
- The same crystal formation
- The same optical properties
👉 Then it is a real ruby—regardless of where it was formed.
Lab Ruby Is Real — But Not Natural
Lab Ruby Is Real — But Not Natural
Lab ruby is real, but it is not rare.
Lab grown ruby meets every gemological standard of a real ruby. It has:
- Identical hardness (9 on Mohs scale)
- The same brilliance and color
- The same durability for daily wear
The only difference is origin:
- Natural ruby → formed in the earth
- Lab ruby → created in weeks using controlled processes
👉 So the real distinction is natural vs lab-created, not real vs fake.

When one ruby costs thousands and another costs a few hundred, it’s natural to question authenticity.
👉 But the price difference is due to rarity—not composition.
