Lab-created blue and white sapphire together in a stud earring creates a colored gemstone piece with the blue-and-white fine jewelry combination at an entry-accessible price: the 1.35 carats of square octagonal blue sapphire provide the rich blue color that makes sapphire jewelry so compelling, while the 0.43 carats of round white sapphire accents create the bright white contrast that makes the blue appear more saturated. Both stones are lab-created corundum - real sapphire composition grown in controlled laboratory conditions - with the hardness and optical properties of natural sapphire. The geometric square octagonal cut adds contemporary design character to the blue stone.
