What do tourmalines have that other minerals don't? The large family of tourmalines offers something for everyone: tourmalines come in incredibly beautifully colored crystals in every color of the spectrum, as valuable gemstones, in a wide variety of shapes, and with unusual properties. Tourmalines simply offer it all. Numerous excellent photographs—from the rare elbaite to the common schorl—showcase the vast array of colors and forms. Attractive, wafer-thin tourmaline slices reveal the colorful interior of the tourmalines. Various reports on the discovery sites document many interesting new finds—for example, from the Laghman Mine and Paprov in Afghanistan, from the Rosina pegmatite on the island of Elba, and, of course, from Madagascar. Everything about the fascinating world of tourmalines—from shapes and colors to discovery sites and the latest finds—can be found in this extraLapis No. 41 Tourmaline II, which builds upon the already classic extraLapis No. 6 Tourmaline.
