Item Description

A classic group of cyclic twinned Cassiterite crystals from Linopolis intergrown to create a showy and eye-catching miniature specimen. The largest twin measures 4.0 cm across. The piece has excellent aesthetics with good crystal form and luster. Overall the piece is in great shape, with only minimal imperfections. There are some reddish iron areas on the piece that could possibly be cleaned away, but it does give the piece character. Rarely does one find three-dimensional display pieces of this material on the market. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
