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. 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.
