From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Garnet design, as well as create a vintage or antique look. One of the oldest gemstones in history, garnet is the birthstone of January. Garnet rings have been popular since Victorian times, and are treasured for their deep red color. Brown gemstones are gaining in popularity and smoky quartz is an affordable choice. A smoky quartz ring goes well with autumn colors and evening wear.
