Kunzite can be found in a wide variety of jewelry styles to suit every buyer. Always attractive, it suffers somewhat from a lack of consumer recognition. However, this can translate to reasonable prices at the counter. In its largest sizes and finest colors, kunzite appeals to discriminating collectors.


Kunzite is the pink-to-violet variety of the mineral spodumene, and gets its color from manganese. It’s most often found in shades of pale pink, but more vivid colors are possible and it can achieve rare hues of vivid violet to purple.

Kunzite’s color can be enhanced by irradiation followed by heating. Whether natural or enhanced, the color can fade when exposed to heat and intense light. It’s a good idea to store kunzite jewelry in a closed jewelry box or case when it’s not being worn.

Kunzite is pleochroic, which means it can display different colors in different crystal directions. Kunzite displays its best, most intense color down the length of its crystals.

Kunzite crystals often have relatively few inclusions, so “clean” finished gems in jewelry are common.

Kunzite can present problems for cutters. It has two directions of cleavage, which means that the gem can split cleanly along those directions. As a result, kunzite has been known to simply fall apart from the pressure applied during faceting. In addition, kunzite’s color is usually concentrated down its length, or C-axis. Cutters must factor these properties into their plans when fashioning gems.

Kunzite appears in a wide variety of shapes and cutting styles. Because many crystals are relatively inclusion-free, step-cut stones are fairly common.

Skilled cutters have fashioned kunzite into every imaginable shape and style. Some have even carved the gem. Also, many kunzites are cut deep to maximize the color.
