Item Description

Most people quite familiar with the blue Kyanites from Barra do Salinas in Brazil, but the specimens from Ribeirao da Folha are much less common on the market, and highly desirable for their unique color and form. This piece is a gorgeous "fan"-like spray filled with dozens if not hundreds of thin, prismatic Kyanite crystals of a dark greenish-black hue. To be honest, this really does not look like Kyanite from any locality, and honestly resembles a species like epidote or an amphibole. Great quality, very little damage and really showy! Valued at $1,000. From the worldwide collection of Tom Campbell. Tom is a mineralogist and mineral collect who works with us here at The Arkenstone. He has over 35 years of experience in the fields of exploration geology, mining, and applied mineralogy, and has even more years under his belt as a collector! Tom has described many new species over the years, and discovered the rare phosphates Tiptopite, Fransoletite and Pahasapaite. Tom was also a co-author on the second edition of the Encyclopedia of Minerals. You can see a list of Tom's published works here ( https://www.irocks.com/thomas-j-campbell-publications-list ).
