Luster is the physical property of minerals which describes the appearance of reflected light from fresh mineral surfaces. Lusters fall into two basic categories: Metallic (opaque and metal-like) and Non-metallic (transparent in fine thin particles immersed in luquid.)
The surface appearance of non-metallic minerals is further described as being adamantine (brilliantly reflecting), vitreous (bright and shiny such as broken glass), earthy, waxy, resinous, pearly, silky, greasy and dull.
With this 15 minerals luster set you get to explore all categories or both metallic and non-metallic luster.
Each mineral specimen is approximately 1 inch in diameter and is numbered (reference card is included.)
