Chameleon Diamonds
A name used to identify a class of colored diamonds (usually
olive) that temporarily change color after having been stored in darkness or
when gently heated. Chameleon diamonds exhibit a range of hues and tones from
light to dark olive (stable color phase) through light to medium yellow
(unstable color phase). After 24-48 hours in darkness, exposure to light
gradually changes the color of a chameleon diamond from the unstable yellow
phase back to the stable olive phase. This is observed as an infinitely
repeatable process.
