Trolleite 6mm Round - 15-16 Inch Stone Type_Artistic Jasper displaying these colors in patternsTrolleite is an extremely rare aluminum phosphate mineral that crystallizes in the form of masses and small prismatic crystals. It is made up of quartz, lazulite, scorzalite, and sometimes lepidolite. It's often found in large masses and can be colorless, light to pale green, bluish green, or bright blue. Trolleite is known for its greasy appearance and subdued shine, even when polished.
