Iko matombo anokosha emaminera here?

Maminari ndeyemakemikari anowanzoitika muchimiro, kazhinji kechimiro chekristalline uye chisati chabudiswa nehupenyu hutsika. Maminera ane rimwe rinokonzerwa nemakemikari, asi dombo rinogona kuva rakawanda yemaminerari akasiyana. Sayenzi yezvicherwa ndeye mineralogy.

Most gemstones are minerals

Minerals have various physical properties. Their description depsnds on their chemical structure and composition. Common distinguishing characteristics include crystal structure and habit, also hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, specific gravity, magnetism, taste or smell, radioactivity, and reaction to acid.

chakaita zvokugadzirwa matombo anokosha

Zvakakosha kusiyanisa pakati pezvigadzirwa zvematombo, nekutevedzera kana kuenzaniswa nematombo.

Synthetic gems are physically, optically and chemically identical to the natural stone, but made in a Factory. In the trade maket, gemstones dealers use often the name “lab created”. It makes the synthetic stone more marketable than “factory created”.

Artificial gemstones

Examples of Artificial stones include cubic zirconia, composed of zirconium oxide and simulated moissanite, which are both gemstones simulants. Imitations copy the look and color of the real stone but possess neither their chemical nor physical characteristics. Moissanite actually has a higher refractive index than diamond and when presented beside an equivalently sized and cut diamond will have more “fire” than the diamond.

matombo

Dombo chinhu chechisikigo, chizere chakasimba cheimwechete kana kupfuura minerals kana mineraloids. Semuenzaniso, Lapis lazuli inzvimbo yakadzika ye-blue metamorphic rock. Nhengo dzayo dzakasiyana-siyana-sedombo rinokosha. Iyo inonyanya kukosha yemaminerari inonzi mapis lazuli ndeye lazurite (25% kusvika 40%), feldspathoid silicate mineral.

Amber, Ammolite, Bone, Copal, Coral, Ivory, Jet, Nacre, Operculum, Pearl, Petoskey ibwe

Mineraloids

A mineraloid isiri yemvura-iyo inenge isina kuratidza crystallinity. Mineraloids ine zvikamu zvemakemikari zvinopesana kunze kwenzvimbo dzakawanda dzinogamuchirwa dzemaminera chaiwo. Semuenzaniso, obsidian iglasi reamorphous uye kwete kristini. Jet inotorwa kubva pakuora kwehuni pasi pekumanikidzika kukuru. Opal imwe imwe mineraloid nekuda kweiyo isina-crystalline.
