Abstract
This is the second part of a three-part series on the origin of color in gem materials. This article discusses colors produced by 1) processes that involve multiple atoms (e.g, blue sapphire, organic products); and 2) a variety of defect structures that are generally created by irradiation (natural or artificial), known collectively as color centers (e.g., green diamond). -- AATA
