From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Lab Sapphire design, as well as create a vintage or antique look. Sapphire has always been associated with the sacred and divine. A sapphire pendant is said to bring serenity and purity to the wearer. A perfect stone for nighttime wear, a black onyx pendant looks elegant and stylish in white or yellow gold.
