💫 Bronze-shadow lore and care
Hypersthene is generally treated today as a historic, varietal or appearance-based name rather than a separate modern mineral species. “Bronzite” overlaps with it in commercial use, while exact placement between Enstatite and Ferrosilite normally requires analytical testing. Large carvings may also contain several orthopyroxene grains or associated minerals rather than one uniform crystal.
Hypersthene-bearing material measures approximately 5–6 on the Mohs scale and has two good cleavage directions meeting close to a right angle. Clean briefly with lukewarm water, mild soap and a soft cloth or brush, then dry completely. Protect polished surfaces from grit, harder gemstones and sharp impacts, and avoid prolonged soaking, solvents, steam and ultrasonic cleaning.
