The mineral was mentioned in 1529 by G. Agricola, but the name argentite was not used till 1845 and is due to W. Haidinger. Old names for the species are Glaserz, silver-glance and vitreous silver. A related copper-rich mineral occurring e.g. in Jalpa, Zacatecas, Mexico, is known as jalpaite. [4]

Silver glance (German: Silberglanz) — is a trivial name used among collectors and mineral traders, as well as miners, geologists and representatives of related craft professions for at least two ore minerals, silver sulfides. [1]: 312 It may refer to: Acanthite, monoclinic silver sulfide, one of the most famous silver ore minerals.
Acanthite is a common silver mineral in moderately low-temperature hydrothermal veins and in zones of supergene enrichment. It occurs in association with native silver, pyrargyrite , proustite , polybasite , stephanite , aguilarite , galena , chalcopyrite , sphalerite , calcite and quartz .
The name argentite is therefore used (confusingly) by some to describe pseudo-cubic pseudomorphs of silver sulphide (acanthite) where the original crystal form of the high-temperature cubic argentite has remained. The correct way to label such specimens would "acanthite, pseudo-cubic" or "acanthite, pseudomorphous after argentite".
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. [5] Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.
Stephanite is a silver antimony sulfosalt mineral with formula: Ag 5 Sb S 4. It is composed of 68.8% silver , and sometimes is of importance as an ore of this metal. [ 5 ]
Stones are still the mainstays of civil construction in India, with stones being used extensively in public buildings, hotels, and temples. They are increasingly being used in homes, with the use of stones now penetrating amongst the growing middle class of India. The success of the commercial stone industry solely depends on defects in rock/stone.
