Idayimane lemvelo kwakuwukuphishekela "okuthandwa" kwabaningi "kanye nentengo ebizayo nabo bavumele abantu abaningi banamahloni. Kepha kule minyaka emibili edlule, intengo yamadayimane lemvelo ayaqhubeka nokuphelelwa yindawo. Kuyaqondakala ukuthi kusukela ekuqaleni kuka-2022 kuze kube manje, ukwehla okupholile ngentengo yamadayimane amabi atshalwe afinyelela kuma-85%. Ngasohlangothini lokuthengisa, amadayimane atshalwe ka-1-carat awile ngaphezu kwama-80% aqhathaniswa nephuzu eliphakeme.
Umphakeli omkhulu kunawo wonke emhlabeni wamadayimane wemvelo - ubhiya ngoDisemba 3, u-Est uzothengiswa emaphethelweni entengo yamadayimane asesibili entengo ye-10% kuya ku-15%.
Abanye abahlaziyi baveze ukuthi ubhiya ubhiya bavame ukubheka ukusikeka okukhulu kwentengo njenge- "yokugcina" ukubhekana nezinguquko zemakethe. Ukusikeka kwamanani amaningi wenkampani kukhombisile ukuphuthuma kwalo ebusweni bomakethe bemakethe. Lokhu futhi kukhombisa ukuthi, njengoba umdondoshiya womkhakha, ubhiya ubhiya obhekene nengcindezi eyakha phansi emakethe wehlulekile ukusekela ngempumelelo intengo yamadayimane.
Ngokusho kwemiphumela engama-2023 ekhishwe ngu-De Beers, imali ephelele yeqembu yawa ngo-34.84% kusuka ku- $ 6.6 billion ngo-202 billion, ngenkathi ukuthengiswa kwedayimane okungama- $ 60 kuya ku- $ 6 billion.
Ngokuqondene nezizathu ezingemuva kwe-dive yakamuva ezitsheni zedayimane, abasebenza emkhakheni bakholelwa ukuthi umnotho onciphisayo, ukuguquguquka kwabathengi okuvela kumadayimane kubucwebe begolide, kanye nokwehla kwenani lemishado kunciphise isidingo samadayimane. Ngaphezu kwalokho, i-CEO yeDe Beers iphinde yathi isimo se-Macroeconomic isishintshile futhi abathengi kancane kancane basuka ekusetshenzisweni kwezimpahla ekusetshenzisweni kwezimpahla ezithambekele, ngakho-ke isidingo sokusebenzisa amadayimane, siyehle kakhulu.
Kwabuye kwahlaziywa ukuthi intengo evuthayo yamadayimane amabi kanye nokwehla kwesidingo semakethe, ikakhulukazi ukuthandwa kwamadayimane atshalwe ngobuciko kunciphise isidingo sabathengi samadayimane emvelo. Intuthuko yezobuchwepheshe inike amandla amadayimane awenze akwazi ukusondela kwikhwalithi yamadayimane lemvelo kodwa ngentengo ephansi, eheha abathengi abaningi, ikakhulukazi ekusebenziseni ubucwebe bezinsuku zonke, futhi bathumba isabelo semakethe samadayimane emvelo.
Njengoba ubuchwepheshe buqhubeka buqhubekisa phambili, izindlela zokukhiqiza zamadayimane atshaliwe ziya ngokuya ziyinkimbinkimbi. Njengamanje, izindlela eziphambili zokukhiqiza amadayimane atshaliwe izinga lokushisa eliphakeme kanye nendlela ephezulu yokucindezela (HPHT) kanye ne-Chemical Vapor Deposition (CVD). Zombili lezi zindlela ziyakwazi ukukhiqiza ngempumelelo amadayimane asezingeni eliphakeme elabhoratri, futhi ukusebenza kahle kokukhiqiza kuhlale kuthuthuka. Ngasikhathi sinye, ikhwalithi yamadayimane atshaliwe futhi ithuthuka, futhi iqhathaniswa namadayimane emvelo ngokuya ngombala, ukucaca nokusikwa.
Njengamanje, inani lamadayimane atshaliwe asetshenzisiwe selivele libambisene nelamadayimane lemvelo. Umbiko wakamuva we-tenoris, isikhungo sokucwaninga ngemakethe yase-US, waveza ukuthi ukuthengiswa kwezitolo ubucwebe obuqediwe e-US kukhuphuke ngo-9.9% ngo-Okthoba 2024, ...
okuthi ubucwebe bedayimane lemvelo bakhuphuka kancane, up 4.7%; Ngenkathi amadayimane atshaliwe afinyelela ekwandeni okungu-46%.
Ngokusho kwesiteji sedatha ye-Statista yaseJalimane, ukuthengiswa kwamadayimane amasiko kuzofinyelela cishe ama- $ 18 billion emakethery yomhlaba wonke ngo-2024, kubalwa imali engaphezu kwama-20% yemakethe yobucwebecwebe.
Imininingwane yomphakathi ikhombisa ukuthi ama-akhawunti okukhiqizwa e-Diamond Monocrystal China cishe angama-95% okukhiqizwa okuphelele komhlaba, isikhundla sokuqala emhlabeni. Ensimini yamadayimane atshaliwe, amandla okukhiqiza ama-China abiza cishe ama-50% esithambeko sokukhiqizwa kwedayimane elitshalwa emhlabeni wonke.
Ngokusho kokuhlaziywa kwedatha ngokubonisana neBain eqinile, ukuthengiswa kwedayimane kwedayimane okulimazayo kweChina ngo-2021 kuzoba ama-carats ayizigidi eziyi-1.4, kanti kulindeleke ukuthi ukuthengiswa kwedayimane kwedayimane kwemakethe ye-China kuzofinyelela ama-carats ayizigidi ezingama-4,8% ka-13.8%. Abahlaziyi bakukhomba ukuthi ngenqubekela phambili yezobuchwepheshe kanye nokuqashelwa kwemakethe, imboni yedayimane elitshaliwe iqala ukukhula ngokushesha.
