A perfect pear shaped stone of good color, 4·70 carats, $50.00. 1962R. Webster Gems I. vii. 129 Kunzite shows a golden-pink or orange glow under long-wave ultra-violet light, and a similar but much weaker effect is seen under the short-wave ultra-violet lamp. Under an x-ray beam kunzite shows a very strong orange fluorescence with a strong and persistent afterglow. When the phosphorescence has died away the stone is found to have changed its colour to a bluish-green; this remains stable provided that the stone is kept away from a stong light. 1973Fortnum & Mason Ltd.
