Izinyathelo ezi-5 ezibalulekile i-International Gemological Institute eyeluleka ukuthi uzilandele lapho uthenga amadayimane namatshe ayigugu

Iningi labathengi bamadayimane namatshe ayigugu emhlabeni wonke bayazazi izindlela ezine zekhwalithi zamadayimane: ukusikwa, umbala, ukucaca, kanye ne-carat - kodwa bashaye indiva umbandela wesihlanu nobaluleke kakhulu wokuthola isitifiketi esigunyazwe emhlabeni wonke sokuhlolwa nokuhlukaniswa.

Ukuthenga kwakho ubucwebe bedayimane nobucwebe bedayimane mhlawumbe kungenye yezinto ezinkulu nezibaluleke kakhulu oyoke uzenze empilweni yakho, hhayi kuphela ngokwemibandela “yemizwelo” kodwa nenani lokutshalwa kwezimali kwezimali okunikezelwe kule nqubo. Lapha wenze ucwaningo lwakho ngokucophelela futhi wakhetha isitolo noma amawebhusayithi ukuthenga idayimane lakho elisha ngemva kokubonisana iningi labangane nomndeni wakho! Nokho, ngomzuzu wokugcina obalulekile ngaphambi kokusebenzisa ikhadi lokuthenga ngesikweletu noma isheke lasebhange, ungase uzizwe ungabaza futhi mhlawumbe uzibuze: Ingabe idayimane lami lizoligcina inani lalo ngempela? Ingabe muhle futhi ungokoqobo njengoba ebukeka? Ingabe kuyinzuzo engiyikhokhayo?

Ngokuqondene nezimpendulo zale “mibuzo emikhulu”, ngeke wazi impendulo yazo uma ungazi ngokugcwele futhi ujwayelene nemibandela emine okuhlolwa ngayo amadayimane. Ngokwesisekelo sawo, yizi: Sika, umbala, ukucaca, ne-carat. Kodwa lapho uhlolisisa inqubo yocwaningo ngaphambi kokuthenga amadayimane, uzothola ukuthi kunenye inkomba yesihlanu ebaluleke kakhulu, okuyisitifiketi sokuhlolwa nokuhlukaniswa esiqinisekisa ukunemba kokukhetha kwakho kanye nenani langempela lamadayimane owathandayo. ithengwe futhi yatshalwa kuyo.  Abanye bangase bathi, amadayimane awahlali efika futhi awathengiswa nesitifiketi sokuhlolwa nokulinganisa, futhi amadayimane owathengile angase abe ngokoqobo noma angabi ngokoqobo kungakhathaliseki ukuthi aqinisekisiwe noma cha. Pho kungani kufanele ngifune isitifiketi sokuhlolwa nokuhlukaniswa?

Ukuhlola: inqubo eqinile yesitifiketi

Amadayimane ayahlolwa, ahlelwe futhi ahlolwe ngokwamazinga omhlaba. Ama-gemologists anolwazi ezindaweni zokucwaninga ezivikeleke kakhulu zisebenzisa amandla aphezulu, ama-microscopes anokucaca okuphezulu, amathuluzi nobuchwepheshe obuthuthukisiwe ukuze batadishe futhi balinganise ukufakwa kwedayimane, ukukhubazeka, ukucwebezela, ukulinganisa kanye nombala wamadayimane. Esebenza ngokuzimela kubavukuzi bedayimane noma abathengisi, la malebhu ahlinzeka ngokuhlolwa okuthembekile nokungachemi, okufana ne-CV yedayimane wonke umuntu azoyazisa kanye nomhlahlandlela othembekile nesithenjwa esisekela inani lakho ledayimane.

Ngiyacelawa Okwengeziwe: Unganciki nje ebufakazini obujwayelekile bomthengisi.

Ubufakazi noma imibiko ekhishwa abenzi bobucwebe ngokuvamile iqukethe amazinga ahlukene olwazi, hhayi imininingwane eqondile ephelele. Kodwa imibiko evela ezindaweni zokucwaninga ngokuvamile ihlanganisa umdwebo wedayimane ezingxenyeni ezimbili eziphambanayo, phezulu nohlangothi, kanye neshadi elinesisindo, ithoni, ukusikeka nama-engeli. kanye namazinga okufakwa ento ngayinye.

Amanye amadayimane athuthukiswa ngobuchwepheshe be-laser noma ukushisa, ukucindezela, noma ezinye izindlela ezithuthukisa umbala noma ukucaca. Umthengi kufanele azi ukuthi idayimane lakhe liye labhekana nanoma iyiphi yalezi zinqubo - ngokuvamile ezingafakwanga esitifiketini esivamile esinikezwa abakha ubucwebe.

Amalabhorethri amaningi anikezela ngezinsizakalo ezengeziwe, okuhlanganisa ukubhala inombolo yesitifiketi esincanyana kumadayimane ukuze asetshenziswe kamuva ekuhlonzeni ucezu, njenge-International Gemological Institute (IGE)IGI). Umdwebo mncane kakhulu ukuthi ungabonwa ngeso lenyama futhi akuthinti ukucaca nhlobo.

Ungalokothi uthenge amadayimane aqoshiwe nanemibala eminingi ngaphandle kwamavidiyo akhulisiwe noma izithombe

Ezikhathini eziningi, abathengi bamatasa kakhulu ngokuthola idayimane “elikhulu” elinemininingwane “engcono kakhulu” ephepheni ngenani elincane lemali. Kodwa-ke, uma kukhulunywa ngamadayimane amise okwefashini (njenge-Cochin Cushion, OvalOval , Emerland Emerald, kanye neNkosazana Princess), isitifiketi sedayimane esisekelwe ngesithombe sizokusiza ukuthi "uqonde" kangcono idayimane lakho.

Yenza inani labo lihlale njalo: Thola isiqinisekiso kumenzi wobucwebe.

Ngaphezu kwesitifiketi sokuhlolwa nokuhlukaniswa, idayimane lakho lingase lifike newaranti; Noma ungathenga isitifiketi sewaranti, njengoba nje uthola lapho uthenga imoto entsha. Ngakho-ke, thenga ngobuhlakani futhi uthole isiqinisekiso kumenzi wobucwebe, indandatho yakho yedayimane izohlala iphephile futhi icwebezela.

Kuye ngokusikwa nokufakwa, amadayimane angakwazi ukucwilisa noma aphule, ngisho nasezintweni ezilula njengokuphakamisa izikhwama zegrosa ngaphandle kwemoto, lapho usebenza engadini, njll.

Ngaphansi kwalesi siqinisekiso, ungaletha ubucwebe esitolo lapho uthenge khona, ngokuvamile njalo ezinyangeni eziyisithupha, ukuze ochwepheshe bakwazi ukuhlola futhi balungise uma kunesidingo. Iwaranti izophinde ihlanganise noma yikuphi ukukhubazeka kokusebenza noma ukwenziwa.

Qiniseka ukuthi uthatha lezi zinyathelo zokuphepha ezengeziwe lapho uthenga ubucwebe bedayimane futhi uqaphele ukuthi ungathengi emthonjeni onganikeli izitifiketi neziqinisekiso njengenketho, ngoba omunye wemisebenzi ebaluleke kakhulu yomcwebi oyigugu kumakhasimende abo ukuhlinzeka ngamadayimane alethayo. injabulo kubaqoqi babo impilo yonke.

Iminyaka engaphezu kweshumi, wasungula i-International Gemological Institute (IGE).IGI) ngokwaso njengesikhungo esihamba phambili se-gemological ukuhlinzeka ngezinsizakalo zokugreda amadayimane, ubucwebe namatshe ayigugu. Esikhathini esifushane, i-International Gemological Institute yazuza ukwethenjwa ngabathengi nezingcweti zobucwebe futhi yaba ireferensi yokuqala yabaningi emhlabeni wonke yokuhlukaniswa nokuhlolwa kobucwebe. I-International Gemological Institute inezitifiketi eziningi  ISO Usanda kuthola isitifiketi sami ISO 17025 kanye no-9001 wokuhlolwa nokuhlukaniswa kwamadayimane akhule elabhorethri.
