Luster
Every mineral's surface looks different, but there are several general ways that a mineral reflects light. Click on the kind of luster that you think our golden cube has!

Metallic luster looks like metal, of course.	A glassy luster is called vitreous.	A plastic-like luster is called resinous.	Adamantine luster is brilliant, as with this diamond.	Pearly luster has a shimmery appearance, like a pearl.	Silky luster has a soft look, just like silk.
