Which materials commonly exhibit a vitreous luster?

Explanation:
Vitreous luster describes a bright, glass-like shine, similar to polished glass. Quartz and glass are classic examples because they have smooth, highly reflective surfaces that scatter light in a way that produces that clear, glassy gleam. Pearls and coral, on the other hand, tend to show a pearly or waxy sheen; moonstone often displays a milky glow called adularescence rather than a pure glassy shine; opal and peridot can have varied appearances, but the most representative and consistently described glassy look comes from quartz and glass.
