Step-by-Step Guide: Testing Mineral's Luster like a PRO

Luster is a vital physical property of minerals, especially in differentiating between sulfides (which have metallic luster) and non-sulfides minerals (non-metallic luster). The luster test (or reflective test) checks how light reflects from the mineral surface. No additional equipment is needed for the luster identification.
