Quick Facts
Formation & Origin
Scheelite is calcium tungstate - the primary ore of tungsten, one of the most important industrial metals. Tungsten has the highest melting point of any metal (3,422 degrees Celsius) and is essential for light bulb filaments, cutting tools, armor-piercing ammunition, and high-temperature alloys.
Scheelite's most spectacular property is its fluorescence under shortwave ultraviolet light - it glows an intense, vivid blue-white that's among the brightest fluorescence of any mineral. This fluorescence is so reliable that prospectors use UV lamps at night to locate scheelite deposits in the field. Walking through scheelite-bearing terrain with a UV lamp is one of the most visually dramatic experiences in field geology.
Gem-quality scheelite is faceted into collectors' gems with remarkable fire (dispersion of 0.026, close to diamond's 0.044). Its main limitation is softness (4.5 Mohs) and perfect cleavage, making it impractical for jewelry but spectacular in a collector's display.
Identification Guide
Scheelite is identified by its honey-yellow color, very high density (6.01 - feels extremely heavy), adamantine luster, and diagnostic intense blue-white fluorescence under shortwave UV light. The UV fluorescence is the fastest and most reliable test.
Distinguish from citrine (much lighter weight, no fluorescence), topaz (harder, lighter), and powellite (similar but fluoresces yellow, not blue). The combination of extreme density and vivid UV fluorescence is unique to scheelite.
Spotting Fakes
Scheelite is a specialist mineral not commonly faked. Synthetic scheelite exists for industrial purposes but isn't sold as collector specimens. The UV fluorescence test is essentially foolproof for identification. For gem-quality faceted pieces, the high density and strong UV fluorescence distinguish it from any glass or other simulant.
Cultural & Metaphysical Traditions
Presented as cultural traditions, not scientific evidence
Scheelite has no traditional metaphysical associations - it's primarily an industrial ore mineral and collector specimen. Modern practitioners who work with it associate the UV fluorescence with revealing hidden truth and accessing energies invisible to normal perception. Its connection to tungsten (the highest melting point metal) links it to endurance and persistence.

Good to Know
Scratch test: At hardness 4.5, Scheelite can be scratched with a copper coin. Handle gently and keep away from harder stones in your collection.
Sources: Found in 4 notable locations worldwide, from China to Brazil.
Heft test: With a specific gravity of 6.01, Scheelite feels surprisingly heavy for its size. This weight is actually a useful identification tool.
