💫 Fire-and-void lore and care
Lava Stone is a broad commercial description rather than one mineral species, chemical formula or universal rock type. Most jewellery material is scoria or strongly vesicular basalt, but porous ceramic, dyed rock, resin composites and industrial slag can resemble it. Perfectly repeated pores, mould seams, pooled colour or glossy material inside cavities may indicate manufacture or treatment.
The compact basaltic framework commonly behaves around 5–6.5 on the Mohs scale, yet thin cavity walls, sharp projections and weathered areas may chip or crumble. Clean briefly with lukewarm water, mild soap and a soft brush, rinse carefully and allow the pores to dry completely. Avoid prolonged soaking, bleach, solvents, steam, ultrasonic cleaning and strong heat, particularly when dye, wax, oil, resin, coatings or mineral-filled cavities may be present.
