Review Minerals-6

This is the mineral galena. What type of luster does it have?

  1. Vitreous

    No. A vitreous luster means that the mineral looks glassy. Galena does not look like it is made of glass.
  2. Shiny

    No. Shiny is not a type of luster.
  3. Metallic

    Yes! A metallic luster means that the mineral looks like it is made of metal. Galena reflects light in the same way that a piece of metal does. If a mineral looks like it is made of metal, it has a metallic luster.
  4. Silver

    No. Silver is a color, not a type of luster. Luster is the way that a mineral reflects light, not is color.
