Luster: Earthy, dull, vitreous, silky. Special Features: Limonite is not a true mineral, instead it is a mineraloid because it lacks a distinct chemical composition and crystalline lattice (2). Limonite is known for being an amorphous mineraloid because it is able to pseudomorph.
Limonite has the non-metallic dull luster. Hence, the correct option for limonite is C. Gypsum is a non-metallic mineral has the multiple lustres such as vitreous and silky. Hence, the correct options are B and D. Talc is the non-metallic mineral, which has the non-metallic pearly or dull luster. Hence, the correct option for talc is C.

Geologic Occurrence. Limonite usually occurs as a secondary material, formed from the weathering of hematite, magnetite, pyrite, and other iron-bearing materials.Limonite is often stalactitic, reniform, botryoidal, or mammillary in habit, rather than crystalline.It also occurs as pseudomorphs and coatings on the walls of fractures and cavities.

Luster describes how a mineral appears to reflects light, and how brilliant or dull the mineral is. The terms used to describe luster are: Metallic (also known as splendent); Submetallic; Vitreous (also known as glassy); Adamantine (also known as brilliant or diamondlike); Resinous (also known as resinlike); Silky; Pearly (also known as mother-of-pearl); Greasy (also known as oily)
Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...
