The effect of blue fluorescence on the appearance of faceted diamonds is a controversial topic in the trade today. Yet inert and fluorescent diamonds are commonly placed next to each other in contemporary jewelry. Half the necklace and one earring in this composite photo are shown under normal lighting conditions (left), and the other half of the necklace and the same earring are shown as they appear under a long-wave ultraviolet lamp (right). For a complete view of the necklace and earrings under both lighting environments, see page 258. The diamonds in the necklace weigh a total of 132 ct, and the pear-shaped center stone in the earring weighs 3.20 ct. Courtesy of Harry Winston, Inc., New York.
