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. Pink tourmaline is a birthstone of October, along with opal, and is a truly special gem. The deep rosy color of a pink tourmaline ring will be sure to attract attention.
