From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Peridot design, as well as create a vintage or antique look. Once considered more valuable than diamonds, a peridot ring is a must have. This "gem of the sun" is the birthstone of August and is a beautiful match for the lush green tapestry of late summer. 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.
