💫 Scribe-and-stars lore and care
Lapis Lazuli is the name of the complete rock, while Lazurite is its principal blue mineral. Visible pyrite is common but not required, and abundant golden flecks do not automatically indicate superior quality. Pale or porous material may be dyed, while wax or oil may be used to deepen colour and improve polish. Historic Badakhshan material is especially renowned, but locality should be supported by documentation rather than appearance alone.
Its mixed composition gives Lapis Lazuli a bulk hardness commonly around 5–5.5, with softer calcite-rich areas and variable porosity. Clean briefly with lukewarm water, mild soap and a soft cloth, testing an inconspicuous area first when treatment is uncertain. Avoid prolonged soaking, acids, solvents, abrasives, strong heat, steam and ultrasonic cleaning, as these may affect calcite, dye, wax, oil, fillings or repaired sections.
