The calcite and quartz-lined vug on the top of this matrix contains a number of beautiful, sharp, wulfenite crystals with orange-red colour. The vug also contains significant fluorite and one patch of beautiful, colourless willemite crystals. The matrix is laced with fluorescent fluorite and willemite. Very colourful under the U/V lamps. As well, one vug has nice, sharp hemimorphite crystals. Really nice specimen!
