Powellite & Stilbite on Mordenite (Soregaroli Coll.)

Item Description

Powellite is the rarest and most desirable mineral from the famed basalts of the Deccan Traps of India. This aesthetic specimen features a 1.5 cm tall, sharp tetragonal crystal of highly lustrous and striated, gemmy, amber powellite dramatically set in a snow-white mordenite vug with two pearlescent stilbite blades. This is a beautiful and very fine example of the combination species. You can barely tell, that the tip of the powellite is (very) gently bruised. Bright yellow fluorescence.
