Undertones VS modifiers
In the world of fancy color diamonds, we apply a large number of terms to describe a stone. Some of these terms portray the stone’s general beauty, some its gemological attributes, and some its color. Many terms were invented by the GIA and became industry standards after decades of use. Other terms, such as “Tint, Tone, Shade, Pure, Dirty, Sweet, a touch of…”, etc.

Chromism in pink diamonds
Pink diamonds from Argyle have been known by polishers, laboratories and traders to exhibit a phenomenon of photochromism whereby their colour can be influenced by illumination of different lights and intensities. These influences are relatively short-lived and most conspicuous after illumination by short wavelength light of high intensity. This effect is particularly noticeable when using instruments to observe fluorescence, such as a DiamondView, which after use with Argyle pink diamonds results in a distinctively bleached or pale colouration.
