This type of luster is known as subadamantine. It is characterized by a shiny, reflective appearance similar to broken glass, often seen in minerals like diamond, zircon, and sphalerite.
Carbon can exhibit both metallic and non-metallic luster depending on its allotrope. In its graphite form, carbon has a metallic luster, appearing shiny and reflective. In contrast, in its diamond form, carbon has a brilliant, non-metallic luster, characterized by its clarity and sparkle. Thus, carbon's luster varies with its structural form.
Platinum has a metallic luster.
No, vitreous luster is non-metallic. It is characterized by a glassy or shiny appearance, similar to that of broken glass or a piece of quartz. Metals exhibit a metallic luster, which is more reflective and more akin to the shine of a polished metal surface.

One example of a mineral with a non-metallic luster is quartz. Quartz typically exhibits a vitreous (glass-like) luster, which can range from transparent to translucent. Other minerals with non-metallic luster include calcite and feldspar, each displaying distinct appearances in terms of shine and light reflection. Non-metallic luster is characterized by a lack of metallic sheen, often appearing dull, pearly, or silky.
Both synthetically made glass and natural quartz crystals exhibit a vitreous luster, which appears similar to glass. This luster is characterized by a shiny, reflective surface. Glass and quartz both have smooth and shiny appearances when polished, leading to the vitreous luster description.
Anthracite luster refers to the shiny, reflective appearance of anthracite coal, which is a high-grade form of coal. This luster is characterized by its glossy, metallic sheen, resulting from its high carbon content and low impurities. Anthracite is known for its clean-burning properties and is often used for heating and industrial purposes. Its distinct luster makes it easily recognizable among other types of coal.
"Pearly" luster in a mineral refers to a sheen that resembles the surface of a pearl, characterized by a soft, iridescent glow. This type of luster often appears in minerals with a layered structure, allowing light to reflect in a way that creates a subtle play of colors. Minerals with pearly luster, such as talc or gypsum, typically exhibit a smooth, somewhat translucent appearance, enhancing their visual appeal.
i dont know sorry No. It is characterized by stiffness.
Diamonds do not have a metallic luster; diamond luster is adamantine to waxy.
