zite is still unknown to many gemstone buyers. But the gemstone world began to pay attention to kunzite when they learned of a 47 carat kunzite ring that President John F. Kennedy had purchased for his wife,[link widoczny dla zalogowanych], Jacqueline. He never had the chance to give her the ring before his tragic death in 1963. The kunzite ring sold for more than $410,000 at a Sotheby's auction of the Estate of Jacqueline Kennedy Onassis in 1996.
Kunzite is the pale pink-violet to light violet species of the mineral spodumene. It is a good hard stone (6.5 to 7.5 on the Mohs scale) with a vitreous luster and good transparency, so it suitable for all kinds of jewelry. It is typically a very light pink or lilac, though we occasionally see some more saturated pinks. We've also found some interesting pieces in an unusual golden pink.
Though most of the fine kunzite in today's market comes from Pakistan and Afghanistan, the gemstone was first discovered in the USA. It was named as a tribute to George F. Kunz, the legendary American mineralogist and buyer for Tiffany & Co,[link widoczny dla zalogowanych], who first described the gem in 1902. Interestingly, the green form of spodumene was also first discovered in the USA, and was named after another American, W.E. Hidden.
Kunzite is strongly pleochroic, meaning there is a color intensity variation when a crystal of it is viewed from different directions. The top and bottom of the crystal reveal the deepest colors. Kunzite is challenging to cut to ensure that the light passes through the gem and accents the desired color.
Kunzite can often be found in sizes over 20 carats,[link widoczny dla zalogowanych], and we occasionally see pieces as large as 50 carats. These days it often receives a portuguese cut,[link widoczny dla zalogowanych], since the extra facets of this cut enhances its brilliance. Most of the kunzite we find is quite clean, and it is not unusual to find large pieces that have no visible inclusions at all, even under magnification.
