Two large, tabular, 5-cm crystals of smoky quartz lie flat against the matrix of sharp, euhedral crystals of cream-colored microcline - with another quartz of the traditional prismatic form growing at their base. Pale greenish-gray albites are here and there. From a small private collection of long-collected Argentine minerals built up by a US expatriate down there. From the Rumi Tueu Mine.
