Collection: Willemite

Willemite (Zn₂SiO₄) is a luminous zinc silicate best known for its brilliant green fluorescence under ultraviolet light. Its most iconic specimens hail from the Franklin and Sterling Hill Mines in New Jersey, USA—famed for their association with franklinite and zincite in one of the world’s most celebrated mineral districts.

Beyond New Jersey, Willemite occurs in several remarkable localities worldwide. The Tsumeb Mine in Namibia produces gemmy, transparent crystals in vivid green and yellow hues; Vieille Montagne Mine in Belgium yields classic European specimens associated with smithsonite and hemimorphite; and Sierra de Los Lamentos in Mexico offers botryoidal and crystalline forms with soft pastel tones. Modern finds from Hunan and Guangxi, China, and smaller occurrences in the DR Congo, Algeria, Sweden, and Zambia further highlight Willemite’s global presence and geological diversity.

Geologically, Willemite forms in the trigonal crystal system, typically within metamorphosed zinc ore bodies and secondary oxidation zones. Its presence often signals the transformation of primary zinc minerals through time, heat, and pressure—producing crystalline beauty from industrial origins.

• Collector appeal: World-class fluorescence, historic and gemmy localities
• Associated minerals: Franklinite, zincite, smithsonite, calcite, hemimorphite
• Metaphysical energy: Enhances clarity, creative expression, and spiritual insight

Whether prized for its scientific rarity or its glowing mystique, Willemite remains a cornerstone of fine mineral collecting. Each Legacy specimen is handpicked for authenticity, fluorescence, and aesthetic impact—offering a true blend of geological wonder and metaphysical resonance.
