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. Legends say that wearing a peridot pendant can bring happiness and contentment. Set in gold and surrounded with diamonds, the power of a peridot is said to intensify. Yellow gold brings out the bronze and golden colors inside a smoky quartz pendant. White gold will highlight the brown and grey tones of the gem. Either way, you can't go wrong.
