SPI Supplies Individual Loose Microanalysis Standard Item, Minerals Group, Almandine

This is an optical micrograph of a polished, carbon coated almandine garnet crystal taken in reflected light. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. Almandine (or almandite) is the iron aluminum end member of the garnets and is a rugged mineral as can be seen from its good polish and prominent relief. Homogeneous garnets are rare so this is a prized material.
