One of a very few tourmalines I found in this old collection with this classic combination from the 1960s or 1970s: nice brilliant lustre, glassy surface, intense color zoning between pink to green. Parallel groth, terminal rhombohedrons and a crossing prismatic pink small crystal between them. This well-known pegmatite mine was discovered in 1991 and produced very colorful tourmalines. Nice gem.
Topaz crystal with intense color, transparence and good brilliance. With a complex termination very rich in faces, where we can observe at least two pyramid forms and the pinacoid, along with two prisms. The base is a cleavage surface.
On a matrix formed by good size crystals of quartz (var. amethyst) some scalenohedral calcite crystals are disposed, brilliant and translucent. Calcite presents intense red fluorescence under LW-UV light. A very aesthetic piece that represent the calcite crystals which appear in the classic Brazilian amethyst geodes.
From an not well-known Brazilian locality for the species, a colorful and aesthetic specimen formed by green malachite rosette-shaped pseudomorphs after azurite scattered over matrix of limonite. Good size and excellent shape.
Group of very nice elbaite crystals, one of them with a good size, transparence and marked color zoning. They are accompanied by a rich group of clevelandite crystals very aerial disposed. We can observe groups of developed lepidolite crystals those give an aesthetic touch to the specimen.
Group of divergent elbaite crystals with good brilliance, defined prismatic faces and complex terminals, almost needle. Good transparence that reveals green color, violet at the upper terminal faces and a delicate red tone in the crystal core. The color zoning is very marked. A gemmy specimen.
