	Large crystal of Ferro-axinite from Puiva, Saranpaul, Polarural, Russia. Ex coll. Claus Hedegaard.
	5 cm Magnetite crystal with Forsterite var. Peridot crystals from Sapat (Kohistan, Pakistan). Mineralogical Association of Dallas' "Minerals from the Roof of the World" display at the TGMS show 2004.
	Helvite crystals to 8 mm on 14 cm Quartz matrix from Navegador Mine, Conselheiro Pe–a, Minas Gerais, Brazil. Luiz Menezes specimen.
	Helvite crystal with Spessartine and Quartz from Tongbei (Yunxiao County, Fujian Province, China). Fabre Minerals specimen.
	Blue Hemimorphite from Sa Duchessa, Iglesias, Sardegna, Italy. Ex coll. Museo de Mineralogia, Roma, Italy.
	Clusters of brown Hubeite xx on Quartz matrix, covered with tabular Apophyllite xx, from Da Ye Mine, Hubei Province, China.

	It looks ugly, but it is actually a relatively pretty piece! Lepidolite-3M Ð a monoclinic Lepidolite with a three-layered molecular structure Ð is one of the rare stacking patterns. This specimen was found by yours truly near a deep, dark pond, deep in the forest at Skuleboda (Väne Ryr, Sweden). Ex coll. Claus Hedegaard.
	Dense aggregates of Lepidolite flakes are cutable. They not easy to cut but do produce interesting cabochons. This is the most common structure type of Lepidolite, Lepidolite-3T Ð triclinic Lepidolite with a three-layered molecular structure. The specimen was collected in the farm Davib-Ost at Karibib (Erongo Region, Namibia). Ex coll. Claus Hedegaard.
	The fine-grained, whitish material inside the green Tourmaline crystals is Lepidolite, formed as an alteration of the Tourmaline. Tourmaline often has microscopic tubes running parallel to the crystal axis. This gives access to external fluids and the Tourmaline appears to be altered Õfrom insideÕ. This specimen was collected in a pegmatite in Uiswater, North of Uis in Namibia. Ex coll. Claus Hedegaard.
	Leucite crystal from Cevta Castellana at Roma, Italy.
	Manganese Vesuvianite crystals from N'Chwaning II Mine at Kuruman, Kalahari Manganese Field, Northern Cape Province, South Africa. Note, Manganese Vesuvianite is a valid species, it is not merely a manganoan Vesuvianite.
	Huge crystal of Manganese Pyrosmalite from Broken Hill, New South Wales, Australia.
	Muscovite crystals from Ferruginha, Minas Gerais, Brasil.
