Description :
Chemical element: S (atomic number 16) Mineral class: Native element Typical color: Bright lemon‑yellow to deep ochre Luster: Resinous to greasy Hardness: 1.5–2.5 on Mohs — very soft Streak: White Fracture: Conchoidal to uneven Your piece shows that characteristic rich yellow, with some earthy gray and brown matrix, which is extremely common for sulfur that forms in volcanic or hydrothermal environments. Sulfur usually crystallizes in: Volcanic fumaroles — where hot gases deposit sulfur as they cool Hydrothermal systems — often alongside gypsum, calcite, aragonite, or realgar Evaporite deposits — where sulfate minerals break down and release elemental sulfur The rough, knobby texture in your specimen suggests massive sulfur, not well‑formed crystals. This is typical of sulfur that condensed from volcanic gases rather than growing slowly in open cavities. Based on the image, your piece has: A natural, unpolished surface showing sulfur’s brittle, crumbly habit Color zoning from bright yellow to muted ochre, likely due to minor impurities or oxidation Attached matrix that hints at its geological setting — possibly volcanic tuff or hydrothermal sediment Collectors often appreciate sulfur for its pure elemental nature, its vivid color, and its role in illustrating geochemical cycles. Sulfur is a bit delicate: Avoid heat — it melts at low temperatures Avoid direct sunlight — can dull the color over time Avoid moisture — it can slowly oxidize Keep away from metals — sulfur can tarnish them What Sulfur Is
