Lintlha tsa Sehlahisoa:
Garnet, e bitsoang ziyawu kapa ziyawu naheng ea China ea boholo-holo, ke sehlopha sa liminerale tse neng li sebelisoa e le majoe a majoe le abrasives mehleng ea boronse.Garnet e tloaelehileng e khubelu.Garnet English "garnet" e tsoa ho Selatine "granatus" (lithollo), e ka 'nang ea tsoa ho "Punica granatum" (kharenate).Ke semela se nang le peo e khubelu, 'me sebōpeho sa sona, boholo le' mala oa sona li tšoana le likristale tse ling tsa garnet.
Li-garnet tse tloaelehileng li arotsoe ka mefuta e tšeletseng ho ea ka lik'hemik'hale tsa tsona, e leng, pyrope, almandine, spessartite, andradite, Grossular, 'me mefuta e fapaneng ke tsavorite, Hessonite le uvarovite.Garnet e theha letoto la litharollo tse peli tse tiileng: (1) garnet iron aluminium garnet manganese aluminium garnet le;(2) Calcium chromium garnet calcium aluminium garnet calcium iron garnet.Garnet ha e na phapang ea maemo lefatšeng.Tseo ho thoeng ke tsa “A” li khetholloa ho ea ka maikutlo a motho.Garnet e tšoanang e ka bolela lipalo tse fapaneng ka matsoho a fapaneng.[1]
