From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Pink Tourmaline design, as well as create a vintage or antique look. 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. This birthstone of October has a luminosity and glow that makes an opal the treasure that it really is. The rainbow of colors on a neutral white background makes an opal ring a perfect match for any outfit.
