Orange and yellow wulfenite crystals with red vanadinite, deep brown to black mottramite, pale yellow mimetite, and tiny purple fluorites. The larger wulfenite crystals are orange, and there is some zoning evident. Ex Scott Braley. First photo: Width of view 6mm. Stack of 70 images. Second photo: Width of view...

Colourless-white radiating sprays of wavellite (or fluorwavellite) with pale pink (ferrian) variscite crystals. The paper describing fluorwavellite states that all specimens analysed were fluorwavellite, but that does not guarantee that wavellite doesn’t occur. Without analysis, you just don’t know as both species are visually indistinguishable. Ex Charles Willett Collection. Joint...
