Calcite on Amethyst with Celadonite

Item Description

Here we have a showy three-dimensional display specimen from Iraí featuring a 3.3 cm, doubly-terminated, off-white colored, modified Calcite scalenohedron, aesthetically perched atop a group of gemmy, lustrous, fine purple color prismatic Amethyst crystals, with minor accenting blue-green Celadonite. The Amethyst crystals measure up to 2.0 cm long, and have an interested tapered habit on the terminations when you look closely. No major damage and quite eye-catching.
From the collection of the recently deceased Alvaro Lucio, arguably the most well-known and accomplished mineral dealer and collector in Brazil. Alvaro graduated with a degree in civil engineering, mining and metallurgy from the Escola de Minas de Ouro Preto in 1949. He began his PhD in the United States and completed it at the Federal University of Minas Gerais. He worked as a professor of extractive metallurgy at UFMG, and also as a technical consultant for several companies in the sector. He was the author of several works, published in books and magazines around the world. He received several honors for his contribution to the development of metallurgy and the introduction of metallurgical physical chemistry in Brazil. His knowledge, solicitousness and enthusiasm will be greatly missed in the mineral world.
