About Lab-Created Rubies:

Lab-created rubies are genuine corundum with essentially the same chemical composition, durability, and Mohs hardness of 9 as natural rubies. The primary difference is their origin — they are grown in a laboratory rather than mined from the earth.

Growth Method: Flame Fusion (Verneuil Process). This process uses extremely high temperatures to melt powdered minerals, which crystallize as they cool, producing genuine ruby crystals.

Lab-created rubies are real rubies, not simulated gemstones or imitations.

FINAL SALE: Thanks for checking out my retiring sale pieces. This item is available only as listed and isn’t eligible for returns, resizing, or modifications due to the reduced pricing.
