From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Emerald design, as well as create a vintage or antique look. The birthstone of May, an emerald ring symbolizes the eternally returning spring. The velvety green color of emerald is a perfect match for spring and summer fashions. 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.
