Kunzite
Afghanistan, Pakistan · 39 specimens · 24.4ct avg
Kunzite is the pink to lilac variety of spodumene, a lithium aluminum inosilicate. It is strongly pleochroic, often showing deeper color along one crystallographic axis and paler tones along others. With Mohs hardness 6.5–7 and perfect cleavage in two directions, it is relatively brittle and must be handled carefully during cutting, setting and wear. Its delicate pastel colors and large crystal sizes make it popular for showy gems and designer pieces.

Value Drivers
Carat weight significantly impacts value at higher quality levels. Kunzite crystals can be large, so big gems are not rare in absolute terms, but large stones that combine strong color, good clarity and skilled cutting are less common and more desirable. Very large gems (20+ carats) with vivid color are especially sought after by collectors and designers.
Color is the primary value driver. The finest kunzite shows a rich, medium to medium-dark pink or lilac with strong saturation, rather than a very pale blush. Because of pleochroism, orientation is critical: stones cut on the correct axis show the best color face-up, while poorly oriented stones may appear too light or grayish. Overly brown or weakly colored material is significantly less valuable.
Kunzite is typically expected to be eye-clean or nearly so, especially in faceted gems. Internal fractures or prominent inclusions reduce both beauty and structural integrity, making clean stones in larger sizes more desirable and relatively scarce.
Cut is especially important due to cleavage and pleochroism. Well-designed emerald, oval and cushion cuts align the most saturated color direction with the table and minimize cleavage exposure. Poor cutting can yield washed-out color, emphasize zoning or lead to breakage during fashioning or wear.
Market Dynamics
Kunzite deposits occur in Afghanistan, Pakistan, Brazil, Madagascar, the United States (California) and other areas. Rough can be found in relatively large crystals, but material with top color and clarity is more limited. Overall supply supports a small but steady fine-jewelry and collector market.
Demand is driven by its pastel pink-to-lilac appeal in fashion and designer jewelry, as well as by collectors interested in large, showy stones. However, its sensitivity to light and cleavage concerns limit its use in heavily worn rings and everyday pieces.
Recent Trends: steady demand from the broader jewelry market, with gradual growth in online and designer channels for well-cut, natural stones.

Insights
Kunzite was named after gemologist George Frederick Kunz, who helped introduce it to the market in the early 20th century.
Some kunzite can fade in color with prolonged exposure to strong sunlight, a phenomenon known as photochromism; careful storage is recommended.
The stone is usually not subjected to complex treatments, though gentle heat or irradiation may be used to adjust color in some cases.
Because of its perfect cleavage, kunzite should not be cleaned with ultrasonic or steam cleaners, and prong settings must be designed to minimize stress points.
Designers often use kunzite in pendants and earrings where its size and color can be showcased with less risk of impact damage.
Demand for kunzite can be fashion-driven; periods of heightened popularity often coincide with broader trends toward pastel and blush-colored gemstones.
