Why are you still paying 96% more for the same stone?

A 3-carat natural Royal Blue sapphire from Burma or Sri Lanka (Ceylon) easily commands $20,000 or more. The lab-grown version—chemically identical, visually indistinguishable, and boasting the exact same refractive index—costs about $120. Same deep velvety blue. Same hardness (9 on the Mohs scale). The only difference is that one sat in the earth for millennia while the other was meticulously grown in a matter of weeks. Use the calculator on the right to see your instant savings.
