Luster refers to the way that an object, such as a mineral, reflects light. The luster may be metallic or nonmetallic. A
mineral with a metallic luster may look golden or silver. A mineral with a nonmetallic luster may look adamantine
(transparent and sparkly like a diamond), pearly, vitreous (glassy), waxy, silky, resinous (like honey), or greasy. Nonmetallic
minerals with little or no luster tend to have an earthy, dull look.
Examine all the mineral samples in your kit one by one to determine if they have a metallic or a nonmetallic luster. Some
minerals may be only partially lustrous. Hold them up to the light and look on all sides for an accurate observation.
Classify each mineral as metallic or nonmetallic in the table.
