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 is the birthstone of September, and one of the most popular gemstones on the jewelry scene today. The deep blue color of a sapphire ring is just right for an evening out. A long time favorite of jewelry designers, aquamarine is the birthstone of March. The diamond-like brilliance of an aquamarine ring is sure to attract attention.
