💫 Iron-earth lore and care
Red Jasper is a descriptive lapidary and geological category rather than one formally defined mineral species. It overlaps with strongly pigmented red Chert, while Carnelian and most red Agate are usually more translucent. Colour alone cannot establish a particular mine, country or named variety, and unusually uniform pigment concentrated around pores or drill holes may indicate dye.
Dense Red Jasper commonly measures approximately 6.5–7 on the Mohs scale and has no continuous rock-wide cleavage, although it remains brittle. Clean sound pieces briefly with lukewarm water, mild soap and a soft cloth or brush, then dry around seams and drill holes. Avoid sharp impacts, abrasive powders, strong chemicals, steam and ultrasonic cleaning when fractures, resin, wax, dye, backing or repairs may be present.
