2.05" Lamprophyllite Crystal Aggregations in Matrix - Russia
This fantastic specimen features sprays of lamprophyllite crystals in matrix. It was collected from Murmansk Oblast, Russia and is mounted to an acrylic display base with mineral tack.
Lamprophyllite is a relatively rare, but widespread mineral that typically forms within alkaline igneous rock. It was named after the Greek words "lampro" (meaning shining) and "phyllo" (meaning leaf) in reference to its vitreous luster, cleavage and leaf like crystal formation. Its chemical composition is (Na,Mn2+)3(Sr,Na)2(Ti,Fe3+)3(Si2O7)2O2(OH,O,F)2 and it typically forms as dark brown, flattened and elongated crystals.
