Created vs Natural Ruby: What's the Difference?

Created ruby and natural ruby are both genuine ruby — chemically, physically and visually the same stone. The difference is simply how they formed: natural ruby is mined from the earth, while created ruby is grown in a laboratory. Both rate 9 on the Mohs hardness scale and show the same vivid red. The right choice comes down to budget, rarity and personal preference.

Both Are Real Ruby

This is the key point that surprises many people: a created ruby is not a fake or an imitation. It has the same chemical composition (corundum coloured by chromium), the same hardness, and the same optical properties as a mined ruby. The only difference is origin — lab versus earth. Imitations (like red glass or other red stones standing in for ruby) are a separate thing entirely, and not what “created ruby” means.

Side-by-Side Comparison

When to Choose Created Ruby

• You want the vivid red look and full durability at a more accessible price.
• You prefer a lab-grown, conflict-free origin.
• You’re buying for everyday wear or gifting and want great value.

When to Choose Natural Ruby

• The rarity and natural origin matter to you personally.
• You’re after a collectible or heirloom stone and the premium is worth it.
• You value the individual character of a mined gem.

Caring for Either Ruby

Both created and natural ruby are tough and easy to care for — warm soapy water and a soft brush keep them bright. See our ruby care tips for the full routine.

Frequently Asked Questions

Is created ruby a real ruby?

Yes. Created ruby has the same chemical composition, hardness and appearance as natural ruby. The only difference is that it is grown in a lab rather than mined. It is not an imitation.

Is created or natural ruby better?

Neither is 'better' - they are the same stone. Created ruby offers the same look and durability at a lower price; natural ruby is valued for its rarity. The right choice depends on your budget and preference.

Can you tell created and natural ruby apart?

To the eye they look the same. Gemmologists can identify subtle differences in inclusions under magnification, but both display the same vivid red and 9 Mohs hardness.

Is created ruby more ethical?

Many people choose created ruby for its lab-grown, conflict-free origin and lower environmental impact, though responsibly sourced natural rubies are also available.
