A solitaire pendant with a lab created oval-cut blue sapphire (1/2 carats (ctw)) set into gleaming crisp 14 karat white and yellow gold setting and matching gold chain. Blue sapphire is the birthstone for September. This stunning pendant has beautiful 1/3 carat (ctw) of lab-grown diamonds that surround in a halo formation around the blue gemstone.

Both have the same chemical composition and atomic structure, producing the very same durability, fire, and sparkle, the only difference is the origin.
