The Quattro™ collection refers to our use of four wide prongs holding the center stones. Although this collection is sometimes detailed further with tiny pavéd diamonds on the tops of these prongs or on the side shoulders of the shanks, it is primarily about simplicity and the bold colors of the center stones. Some of our favorites are golden rutilated quartz, satin or milky aquamarine, green and red tourmaline, and white and green moonstone.
