Njengegunya kwishishini lezacholo, i-GIA (iGemological Institute of America) yaziwa ngobuchwephesha bayo kunye nokungakhethi cala ukususela ekusekweni kwayo. I-GIA ezine Cs (umbala, ukucaca, ukusika kunye nobunzima be-carat) ziye zaba ngumgangatho wegolide wovavanyo lomgangatho wedayimani kwihlabathi jikelele. Kwintsimi yeeperile ezikhuliswe, i-GIA nayo idlala indima ebalulekileyo, kwaye i-GIA yayo ye-7 yexabiso leperile (ubukhulu, imilo, umbala, umgangatho weeperile, ukukhazimula, umphezulu kunye nokuhambelana) zibonelela ngesiseko sesayensi sokuchongwa kunye nokuhlelwa kweeperile. Nangona kunjalo, kukho inani elikhulu leeperile zokuxelisa kunye neeperile eziphantsi kwimarike, ezinqabileyo kunye nenkohliso, okwenza kube nzima kubathengi ukuba bahlule. Abathengi bahlala bengenabo ubuchwephesha kunye namava okuhlula iiperile kubuxoki, kwaye abarhwebi banokuthatha ithuba le-asymmetry yolwazi ukulahlekisa abathengi.
Ngokukodwa, izizathu zokuba kutheni kunzima ukuchonga iiperile zinokubalelwa ikakhulu kule miba ilandelayo:
1. Ukufana okuphezulu ngenkangeleko
Ubume kunye nombala: Ubume beeperile zendalo zihlukile, kunzima ukulawula ngokupheleleyo okufanayo, kwaye umbala ugqithise kakhulu, uhamba kunye ne-fluorescence enemibala yendalo. Iiperile zokulinganisa, ezinjengezo zenziwe ngeglasi, iplastiki okanye amaqokobhe, zinokumila ngokuthe rhoqo, kwaye umbala unokufana noweeperile zendalo ngokusebenzisa iindlela zokudaya. Oku kwenza kube nzima ukwahlula ngokuthe ngqo okwenyani kwi-fake ngokusekelwe kwinkangeleko yodwa.
Iglosi: Iiperile zendalo zinokukhanya okukhethekileyo, iglosi ephezulu kunye nendalo. Nangona kunjalo, ezinye iiperile ezikumgangatho ophezulu zingaphathwa ngeenkqubo ezikhethekileyo zokuphumeza umphumo ofanayo we-luster, ukwandisa ubunzima bokuchongwa.
2. Ukwahluka okuncinci kwiimpawu zomzimba
Ukuchukumisa kunye nobunzima: Iiperile zendalo ziya kuziva zibanda xa zichukunyiswa, kwaye zinengqiqo ethile yobunzima. Nangona kunjalo, lo mahluko unokuthi ungabonakali kumntu ongeyongcali, njengoko ezinye iiperile zokulinganisa zinokuphathwa ngokukodwa ukulinganisa oku kuchukumisa.
Springiness: Nangona springiness iiperile yokwenyani idla ngokuba phezulu kunaleyo perile fake, lo mahluko kufuneka kuthelekiswe phantsi kweemeko ezithile ukuze kuqondwe ngokucacileyo, kwaye kunzima kubathengi abaqhelekileyo ukuba basebenzise njengesiseko esiphambili sokuchongwa.
3. Iindlela zokuchongwa zintsonkothile kwaye zahlukene
Uvavanyo lwefriction: Iiperile zokwenyani zivelisa amabala amancinci kunye nomgubo emva kokuhlikihla, ngelixa iiperile zomgunyathi zingenzi. Nangona kunjalo, le ndlela idinga isixa esithile sobuchule kunye namava, kwaye inokubangela umonakalo othile kwiperile.
Ukuhlolwa kweglasi yokukhulisa: Izitenxo ezincinci kunye nokungafezeki kumphezulu weeperile zokwenyani kunokubonwa kusetyenziswa iglasi yokukhulisa, kodwa le ndlela ikwafuna ulwazi olukhethekileyo kunye namava.
Ezinye iindlela zokuvavanya: ezifana nevumba elivuthayo, i-ultraviolet irradiation, njl., nangona ezi ndlela zisebenza kakuhle, kodwa umsebenzi unzima kwaye unokubangela umonakalo ongenakuguqulwa kwiperile, ngoko ke ayifanelekanga kubathengi abaqhelekileyo.
Ukuqaliswa kweteknoloji yeRFID
Itekhnoloji yeRFID (iRadio Frequency Identification) ekwaziwa ngokuba kukuchongwa kwamaza kanomathotholo, bubuchwephesha bonxibelelwano obuchonga into ekujoliswe kuyo ngemiqondiso kanomathotholo kwaye ifunde kwaye ibhale idatha efanelekileyo. Akufuneki ukuseka uqhagamshelwano lomatshini okanye optical phakathi kwenkqubo yokuchonga kunye nethagethi ethile, kwaye inokuchonga ithagethi ethile ngemiqondiso yerediyo kwaye ifunde kwaye ibhale idatha efanelekileyo.
Indawo yokusetyenziswa kweteknoloji yeRFID
Itekhnoloji yeRFID isetyenziswa kakhulu kulungiselelo lolungiselelo, ulawulo lwekhonkco lokubonelela, ukuchongwa kwesazisi, ukongamela okuchasene nokuthengiswa komgunyathi, ulawulo lwezithuthi, ukulandelela izilwanyana kunye namanye amacandelo. Umzekelo, isetyenziselwa ukulandelela imithwalo kwishishini lolungiselelo, kulawulo lokungena kunye nokuphuma kwabasebenzi kwinkqubo yokulawula ukufikelela, kunye nokulandelelwa kokhuseleko lokutya.
Ukuze kuncedwe abathengi bahlule ngcono phakathi kweeperile zokwenyani kunye nezobuxoki, i-GIA kunye ne-Fukui Shell Nuclear Plant kutshanje zisebenze kunye ukuze zisebenzise i-RFID (i-radio frequency identification) iteknoloji kwintsimi yeeperile eziphuculweyo, ukudala ixesha elitsha lokulandela umkhondo weperile kunye nokuchongwa. I-Fukui Shell Nuclear Plant ingenise ibhetshi ye-akoya, i-South Sea kunye neeperile zaseTahiti eziqulethe ii-chips ze-RFID ezizodwa kwi-GIA. Ezi chips RFID zifakwe kwi pearl core ngokusebenzisa i patented pearl ungqinisiso iteknoloji, ukuze iperile nganye "ikhadi ID". Xa iiperile zivavanywa yi-GIA, umfundi we-RFID unokubhaqa kwaye abhale inombolo yereferensi yokulandelela iiperile, ezinokuthi zifakwe kwingxelo yokuhlelwa kweeperile ze-GIA. Ukusetyenziswa kobu buchwepheshe kubonisa inyathelo elibalulekileyo kwishishini leperile ekuphuculeni ukulawulwa komgangatho wemveliso kunye nokulandelwa kokuchasana nomgunyathi.
Ngokunyuka kweemfuno zabathengi zokuzinza kunye nokucaca kwemveliso, le ntsebenziswano phakathi kwe-GIA kunye neSityalo seNyukliya se-Fukui Shell ibaluleke kakhulu. Ukudibanisa itekhnoloji yeRFID kunye nengxelo yeeperile ezifuywayo ye-GIA ayinikezi kuphela abathengi ukuqonda okucacileyo kwemvelaphi, inkqubo yokukhula kunye neempawu zomgangatho weperile nganye, kodwa ikwakhuthaza ukungafihli kulo lonke unikezelo lweperile. Oku akuncedi kuphela ekulweni neemveliso zomgunyathi kunye nezingekho mgangathweni kwimarike, kodwa konyusa ukuthembela kwabathengi kushishino lweeperile. Ukusetyenziswa kobuchwephesha beRFID kongeze amandla amatsha kuphuhliso oluzinzileyo lweshishini leperile.
Kwinkqubo yokulandelela ngokuchanekileyo ukukhula, ukuqhutyelwa phambili kunye nokuthengiswa kweeperile, amashishini kunye nabathengi banokuqonda ngakumbi nge-intuitively ukubaluleka kophuhliso oluzinzileyo. Oku akuyi kunceda kuphela ukunciphisa inkunkuma yemithombo kunye nokungcoliseka kwendalo, kodwa kwakhona kukhuthaze abavelisi abaninzi beeperile ukuba bamkele iindlela zokuvelisa ezihambelana nokusingqongileyo kunye nezizinzileyo, kunye nokukhuthaza ngokubambisana ukuguqulwa kohlaza kwishishini leperile.
