💫 Many-coloured lore and care
Polychrome Jasper is a modern trade name rather than a separate mineral species or ancient historical variety. The best-known commercial material comes from northwestern Madagascar, although colour alone cannot confirm origin. It differs from Ocean Jasper, which is especially recognised for orbicular circles, while Polychrome Jasper is better known for sweeping colour fields, landscape bands and map-like mineral lines.
Dense material commonly measures approximately 6.5–7 on the Mohs scale, but open fractures, porous areas and repaired seams may be more vulnerable. Clean briefly with lukewarm water, mild soap and a soft cloth, then dry thoroughly. Avoid abrasive cleaners, strong chemicals, sudden temperature changes, prolonged soaking, steam and ultrasonic cleaning when fractures, glue, fillings or uncertain treatments may be present.
