Metallic Luster:
* Metals: Gold, silver, copper, aluminum, iron, steel. These materials have a shiny, reflective surface that reflects light evenly.
* Pyrite (Fool's Gold): A mineral with a metallic luster, often mistaken for gold due to its bright, golden appearance.
* Graphite: A form of carbon with a metallic luster, though it's not as shiny as true metals.
Vitreous Luster:
* Glass: A transparent or translucent material with a smooth, glassy appearance that reflects light evenly.
* Quartz: A common mineral with a glassy luster.
* Obsidian: A volcanic glass with a glassy luster, often black in color.
Subvitreous Luster:
* Feldspar: A common mineral group with a slightly duller luster than glass.
* Gypsum: A mineral with a pearly, subvitreous luster.
Adamantine Luster:
* Diamond: The most well-known material with adamantine luster, reflecting light brightly and brilliantly.
* Zircon: A gemstone with a high refractive index, giving it a bright, adamantine luster.
Resinous Luster:
* Amber: A fossilized tree resin with a warm, resinous luster.
* Copal: A younger form of resin with a similar luster to amber.
Pearly Luster:
* Mother-of-pearl: The iridescent inner layer of some mollusk shells, known for its pearly luster.
* Opal: A mineral with a play of color, often exhibiting a pearly luster.
* Moonstone: A feldspar with a pearly, opalescent luster.
Silky Luster:

* Coal: A black, sedimentary rock with a dull luster.
Other Luster Types:
* Earthy: Rough, non-reflective surface, like soil.
* Waxy: Smooth, slightly greasy appearance, like beeswax.
* Greasy: Oily, reflective surface, like some minerals.
It's important to note that some materials can exhibit more than one type of luster, depending on factors like the surface quality and the angle of light.
