Njengesiphathimandla embonini yobucwebe, i-GIA (Gemological Institute of America) yaziwa ngobungcweti bayo nokungakhethi kusukela yasungulwa. I-GIA's four Cs (umbala, ukucaca, ukusika kanye nesisindo se-carat) isiphenduke indinganiso yegolide yokuhlolwa kwekhwalithi yedayimane emhlabeni wonke. Emkhakheni wamaparele akhulisiwe, i-GIA nayo idlala indima ebalulekile, futhi izici zayo ze-GIA 7 zenani leparele (usayizi, ukwakheka, umbala, ikhwalithi yamaparele, ukucwebezela, ingaphezulu kanye nokuhambisana) inikeza isisekelo sesayensi sokuhlonza nokuhlukaniswa kwamaparele. Kodwa-ke, kunenani elikhulu lamaparele okulingisa namaparele aphansi emakethe, angama-shoddy futhi angamanga, okwenza kube nzima kubathengi ukuhlukanisa. Abathengi bavame ukuntula ulwazi nolwazi lokuhlukanisa amapharele kulawo mbumbulu, futhi abathengisi bangase basebenzise leli thuba le-asymmetry yolwazi ukuze badukise abathengi.
Ikakhulukazi, izizathu zokuthi kungani kunzima ukuhlonza amaparele zingabalelwa ikakhulukazi kulezi zici ezilandelayo:
1. Ukufana okuphezulu ngokubukeka
Ukuma nombala: Ukuma kwamaparele emvelo kuhlukile, kunzima ukubusa ngokuphelele okufanayo, futhi umbala ushintshashintsha kakhulu, uhambisana ne-fluorescence enemibala yemvelo. Amaparele okulingisa, njengalawo enziwe ngengilazi, ipulasitiki noma amagobolondo, angaba nesimo esivamile, futhi umbala ungase ufane nowamaparele emvelo ngokusebenzisa amasu okudaya. Lokhu kwenza kube nzima ukuhlukanisa ngokuqondile okwangempela kokungamanga ngokusekelwe ekubukekeni kuphela.
I-Gloss: Amaparele emvelo anokukhanya okuyingqayizivele, ukucwebezela okuphezulu kanye nemvelo. Kodwa-ke, amanye amaparele okulingisa asezingeni eliphezulu angabuye aphathwe ngezinqubo ezikhethekile zokufeza umphumela ofanayo wokukhanya, okwandisa ubunzima bokuhlonza.
2. Umehluko omncane ezicini zomzimba
Ukuthinta nesisindo: Amaparele emvelo azozizwa ebanda lapho ethintwa, futhi abe nomuzwa wesisindo esithile. Kodwa-ke, lo mehluko ungase ungabonakali kumuntu ongeyena uchwepheshe, njengoba amanye amaparele okulingisa angaphathwa ngokukhethekile ukuze alingise lokhu kuthinta.
I-Springness: Nakuba i-springness yamaparele wangempela ngokuvamile iphakeme kunaleyo yamaparele mbumbulu, lo mehluko udinga ukuqhathaniswa ngaphansi kwezimo ezithile ukuze ubonakale ngokucacile, futhi kunzima kubathengi abajwayelekile ukuthi basebenzise njengesisekelo esiyinhloko sokuhlonza.
3. Izindlela zokuhlonza ziyinkimbinkimbi futhi zihlukahlukene
Ukuhlolwa kwe-Friction: Amaparele angempela akhiqiza amabala amancane nezimpushana ngemva kokuwahlikihla, kuyilapho amaparele mbumbulu awakhiphi. Nokho, le ndlela idinga inani elithile lekhono nolwazi, futhi ingase ibangele umonakalo othile epareleni.
Ukuhlola ingilazi ekhulisayo: Ukungalungi okuncane nokungapheleli ebusweni bamaparele angempela kungabonwa kusetshenziswa ingilazi yokukhulisa, kodwa le ndlela idinga nolwazi olukhethekile nolwazi.
Ezinye izindlela zokuhlola: njengephunga elivuthayo, imisebe ye-ultraviolet, njll., nakuba lezi zindlela zisebenza kahle, kodwa ukusebenza kuyinkimbinkimbi futhi kungase kubangele umonakalo ongenakulungiseka kuparele, ngakho-ke ayifanele abathengi abavamile.
Ukwethulwa kobuchwepheshe be-RFID
Ubuchwepheshe be-RFID (Radio Frequency Identification) okwaziwa nangokuthi i-radio frequency identification, ubuchwepheshe bezokuxhumana obukhomba okuqondiwe okuthile ngamasignali omsakazo futhi bufunde futhi bubhale idatha efanele. Ayidingi ukusungula ukuthintana kwemishini noma kokubona phakathi kwesistimu yokuhlonza nento ethile eqondiwe, futhi ingakwazi ukubona okuqondiwe okuthile ngamasignali omsakazo futhi ifunde futhi ibhale idatha efanele.
Inkambu yohlelo lokusebenza yobuchwepheshe be-RFID
Ubuchwepheshe be-RFID busetshenziswa kakhulu kwezokuthutha, ekulawulweni kwe-supply chain, ekuhlonzeni umazisi, ekugadweni okulwa nokuzenzisa, ekuphathweni kwethrafikhi, ekulandeleni izilwane nakweminye imikhakha. Isibonelo, isetshenziselwa ukulandelela impahla embonini yezokuthutha, ekulawuleni ukungena nokuphuma kwabasebenzi ohlelweni lokulawula ukufinyelela, kanye nokulandelelwa kokuphepha kokudla.
Ukuze kusizwe abathengi bahlukanise kangcono phakathi kwamaparele angempela namanga, i-GIA kanye ne-Fukui Shell nuclear Plant muva nje zisebenze ndawonye ukuze zisebenzise ubuchwepheshe be-RFID (i-radio frequency identification) emkhakheni wamaparele athuthukisiwe, okudala inkathi entsha yokulandela nokuhlonza amaparele. I-Fukui Shell Nuclear Plant ithumele inqwaba yamaparele e-akoya, oLwandle OluseNingizimu kanye namaparele e-Tahiti aqukethe ama-RFID chips ahlukile ku-GIA. Lawa ma-chips e-RFID ashumekwe ku-pearl core ngobuchwepheshe bokuqinisekisa ubuqiniso beparele, ukuze iparele ngalinye libe "nekhadi le-ID". Lapho amaparele ehlolwa yi-GIA, umfundi we-RFID angakwazi ukubona futhi aqophe inombolo eyinkomba yokulandela yamaparele, engase ifakwe embikweni we-GIA wokuhlukaniswa kwamaparele. Ukusetshenziswa kwalobu buchwepheshe kuphawula isinyathelo esibalulekile semboni yeparele ekuthuthukiseni ukulawulwa kwekhwalithi yomkhiqizo kanye nokulandelelwa kokulwa nomgunyathi.
Ngokukhula kwezidingo zabathengi zokusimama nokuba sobala komkhiqizo, lokhu kubambisana phakathi kwe-GIA ne-Fukui Shell Nuclear Plant kubaluleke kakhulu. Ukuhlanganisa ubuchwepheshe be-RFID nombiko weparele elilinyiwe le-GIA akunikezi nje kuphela abathengi ukuqonda okucacile ngemvelaphi, inqubo yokukhula kanye nezici zekhwalithi zeparele ngalinye, kodwa futhi kukhuthaza ukubonakala obala kulo lonke uchungechunge lokunikezwa kweparele. Lokhu akusizi nje kuphela ukulwa nemikhiqizo ewumgunyathi kanye nentula emakethe, kodwa futhi kuthuthukisa ukuthembela kwabathengi embonini yamaparele. Ukusetshenziswa kobuchwepheshe be-RFID kwengeze umfutho omusha ekuthuthukisweni okusimeme kwemboni yamaparele.
Enqubweni yokulandelela ngokunembile ukukhula, ukucubungula nokuthengiswa kwamaparele, amabhizinisi nabathengi bangaqonda ngokunembile ukubaluleka kwentuthuko esimeme. Lokhu ngeke kusize nje ukunciphisa imfucuza yezinsiza kanye nokungcoliswa kwemvelo, kodwa futhi kukhuthaze abakhiqizi abaningi beparele ukuba basebenzise izindlela zokukhiqiza ezinobungani bemvelo nezisimeme, futhi ngokuhlanganyela bakhuthaze ukuguqulwa okuluhlaza kwemboni yamaparele.
