What is a lab sapphire?

A lab-grown sapphire is a gemstone that is created in a laboratory using advanced techniques that replicate the natural conditions in which stones form. While identical in composition and appearance to natural sapphires, lab-grown sapphires are much more affordable and offer an ethical and sustainable choice without compromising on beauty.
