Authentic Star Mica on Cathedral Quartz – Minas Gerais, Brazil
This exquisite specimen features radiant star-like clusters of muscovite mica perched atop a cathedral-form quartz base. Mined in the renowned gem-producing region of Minas Gerais, Brazil, it’s a stunning example of nature’s artistry—a visual treat that will enhance any mineral collection.
Geological Formation & Origin
Star mica refers to muscovite crystals that exhibit a unique radiating, star-shaped habit, often caused by twinning and sheetlike growth. These formations occur within metamorphic environments where mica and quartz develop together under heat and pressure. “Cathedral” quartz features step-like growth patterns along its crystal faces, giving it a layered, architectural appearance—hence the name. Minas Gerais is globally respected for its rich pegmatite and metamorphic formations producing muscovite and exceptional quartz specimens.
Collector & Display Appeal
This specimen is highly prized for its eye-catching contrast: bright golden mica stars against clear, structured quartz. Perfect for display cases or as a focal point in a mineral collection, its aesthetic richness and natural formation make it a unique standout.
Care & Handling
Both mica and quartz are delicate—handle the specimen gently. Keep in a stable, dust-free environment. To clean, use a soft brush or compressed air use with extreme care; avoid water, cleansers, or solvents to preserve both minerals’ natural beauty.
