This gem was discovered around the early 1900's and named after
G.F. Kunz, who was Tiffany's chief gemologist at the time. It requires special
skills of the cutter to bring out the beauty of this gem. Kunzite's cellular
structure gives it perfect cleavage and so it is very sensitive to pressure
along this cleavage plane. Orientation of the gem material is critical to
successful faceting of this material. Kunzite is in the spodumene group and the
lithium in its chemical composition gives it a wonderful pink-violet color that
compliments either fall or spring wardrobes. It shows its color well in larger
sizes. Since it is a pastel gem, small sizes tend to be very pale. Kunzite needs
a certain amount of mass to bring out its color. Keep kunzite out of direct sun
or high heat because it can fade.
