Vitreous describes the appearance of which surface?

Explanation:
Vitreous luster describes a glass-like surface appearance. When light strikes a gem with this sheen, reflections are bright and crisp, similar to polished glass. It’s the most common type of luster for faceted gemstones and gives a clean, brilliant shine. This contrasts with dull waxy luster (low, greasy shine), pearly luster (soft, nacreous iridescence), or metallic luster (strong, metal-like reflection). So the glass-like surface shine is the best match for vitreous.
