Description
This poster shows a whopping 162 specimens, carefully selected to include those most likely to be encountered by the student and collector. Over 20,000 photographs were reviewed to select specimens that would best show a diversity of colour, habit, lustre, and crystals. These magnificent minerals are presented by class: native elements, carbonates, sulphates, suflides, halides, oxides, phosphates, organics, and silicates. The silicates are such a large group that the bottom three rows are devoted to them. They are grouped by subclass, such as nesosilicates, sorosilicates, and cyclosilicates. All of the popular gemstones are shown.
