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. Gem of hot summer nights and steamy red sunsets, ruby is the birthstone of July. Show the world the passions within you with a fiery ruby ring.
