Ngokusekelwe embhalweni onikeziwe, yisho izici ezithile zeparele.
Context:Iparele liyinto eqinile, ecwebezelayo ekhiqizwa ngaphakathi kwezicubu ezithambile (ikakhulukazi ingubo) ye-mollusk enamagobolondo ephilayo noma esinye isilwane, njenge-conulariids yamagugu. Njengesigqoko se-mollusk, iparele lakhiwe nge-calcium carbonate (ikakhulukazi i-aragonite noma ingxube ye-aragonite ne-calcite) esefomini elincane le-crystalline, eye yabekwa izingqimba ezihlangene. Iparele elihle kakhulu liyindilinga futhi libushelelezi, kodwa kunezimo eziningi ezaziwa ngokuthi amaparele e-baroque. Sekungamakhulu amaningi eminyaka amaparele emvelo asezingeni eliphakeme ehlonishwa kakhulu njengamatshe ayigugu nezinto zobuhle. Ngenxa yalokhu, iparele liye laba isingathekiso sokuthile okuyivelakancane, okuhle, okuhlaba umxhwele nokuyigugu.
1. Iparele liyinto ekhazimulayo futhi eqinile ekhiqizwa ngaphakathi kwegobolondo lezilwane ezinwabuzelayo noma amanye amagobolondo. 2. Njengama-shell amaparele nawo akhiwe nge-calcium carbonate. 3. Iparele Elihle liyindilinga futhi libushelelezi ngokuphelele, kodwa lingaba nezimo ezihlukahlukene njengamaparele e-baroque. 4. Amaparele emvelo asezingeni eliphakeme kakhulu abhekwa njengamatshe ayigugu. 5. Njengoba amaparele emnandi, engavamile futhi eyigugu, aye aba umfanekiso.
