Wulfenite

In practice, wulfenite value is determined more by crystal size, perfection and aesthetic arrangement than by carat weight. Larger, undamaged, well-formed crystals with vivid color are rarer and more valuable to collectors, while broken or heavily chipped pieces are much less desirable.

Color is a primary value factor. The finest wulfenite exhibits intense, saturated orange or yellow hues with strong luster. Stones that are pale, heavily brownish or dull command lower prices. Even color across crystals mounted on matrix specimens is especially prized.

For wulfenite, clarity equates to the transparency and surface perfection of the crystals. Transparent to translucent crystals with minimal internal cracks and clean, unpitted surfaces are more desirable than cloudy or heavily fractured material.

Wulfenite is almost never cut as a gemstone due to its extreme fragility; value is based on natural crystal habit and aesthetic display. Occasional faceted stones exist as curiosities but are extremely rare, fragile and not suitable for wear.

Wulfenite occurs as a secondary mineral in the oxidized zone of lead deposits in localities worldwide, including Arizona and New Mexico (USA), Mexico, Morocco, Austria and others. Fine, well-crystallized specimens are rare and typically recovered by mineral collectors rather than commercial mining.

Demand is highly concentrated in the mineral collector market, where top specimens can command significant prices. There is virtually no mainstream jewelry demand due to the mineral's fragility and lead content.
