Diamonds in all colors are drawing attention

Spurred, perhaps, by Jennifer Lopez’s 6.10-ct. pink diamond engagement ring by Harry Winston, colored diamonds are in demand. Feeding the frenzy, spring issues of fashion magazines present a plethora of colored diamond jewelry.

When customers ask, educate them about the origin of the hues. A trace element of nitrogen yields yellow, for example, and boron or hydrogen blue. Green diamonds are caused by radiation, pinks and reds are a mystery, and those are just natural colors. Treatments also are used to create colors in diamonds.

Also explain the importance of cut: a radiant cut holds color, a round cut can diffuse it. A larger culet enhances color in pear, oval and marquise shapes.

Mountings matter – yellow and brown diamonds stand out against white metals but recede against yellow. White metal enhances blue diamonds, but yellow metal detracts from them.
