Product Description

The STEMAids Twenty Mineral Specimen Collection brings 20 mineral samples together for comparative Earth science study. Learners can examine observable properties such as colour, lustre, texture, crystal form and surface features before using an approved identification key.

Physical specimens make mineral classification more tangible than photographs alone. Teachers can use the collection for geology demonstrations, observation worksheets and introductory identification exercises. The exact mineral names, specimen sizes, grades and presentation format must be confirmed from the approved STEMAids packing list.
