Labradorite
Madagascar, Finland · 9 specimens · 19.8ct avg
Labradorite is a plagioclase feldspar (typically intermediate between andesine and bytownite) best known for labradorescence—a vivid play-of-color sheen that appears as blues, greens, golds and other hues when light hits from certain angles. Base body color is usually gray to dark gray, though some material is nearly black or light. With Mohs hardness about 6–6.5 and good toughness, it is suitable for many types of jewelry when properly set.

Value Drivers
Carat weight influences value mainly through the size of cabochons and statement pieces that can display large, uninterrupted areas of labradorescence. Larger, clean slabs or cabochons showing strong, multicolored sheen are more desirable than small pieces, but basic commercial material is readily available in many sizes.
Color and quality of labradorescence are primary value drivers. The best labradorite exhibits bright, saturated flashes of blue, green, gold or multi-hued 'spectrolite' effects against a contrasting dark background. Weak, patchy or limited sheen, or a very light, washed-out body color, reduces value.
As an opaque to translucent material, clarity is evaluated by surface integrity and internal coherence. Clean, stable pieces with minimal fractures, pits or cloudy zones that interfere with labradorescence are preferred. Excessive cracking or roughness disrupts the sheen and lowers desirability.
Labradorite is usually cut as cabochons or flat-backed freeforms, oriented carefully so that the labradorescent play-of-color is maximized and centered on the face. A high-quality polish is essential to bring out a mirror-like surface that enhances the optical effect. Poor orientation can result in dull stones with little visible sheen.
Market Dynamics
Labradorite is mined in several countries, including Canada, Finland (spectrolite), Madagascar, Russia and others. Overall supply of commercial-grade material is substantial, supporting widespread use in jewelry and decorative objects, although high-end spectrolite with intense, multi-colored sheen is more limited.
Demand is strong in both fashion and artisan jewelry markets, driven by its distinctive optical effect and relatively modest price. High-quality spectrolite from Finland is particularly prized among designers and collectors who seek vivid, multi-hued sheen.
Recent Trends: steady demand from the broader jewelry market, with gradual growth in online and designer channels for well-cut, natural stones.

Insights
The stone was first described from Labrador, Canada, which gave labradorite its name.
Spectrolite is a trade name for particularly colorful, high-grade labradorite from Finland, with a broader color palette and more intense labradorescence than typical material.
Labradorite is often used in large statement pendants, rings and cuffs, where its play-of-color can be viewed over a broad surface area.
Because the optical effect is directional, each cabochon must be individually oriented; this adds to cutting labor compared with more straightforward opaque stones.
Some labradorite is translucent to semi-transparent and can be faceted to show internal blue flashes, though this is a smaller segment of the market.
In metaphysical circles, labradorite is associated with intuition and transformation, which supports demand for tumbled stones and bead strands.
