Mhando dzemadhaimondi iwe unofanirwa kuziva usati watenga diamondi

Madhaimani agara achidiwa nevanhu vazhinji, vanhu vanowanzotenga madhaimani sezororo zvipo zvavo kana vamwe, uye kune mamwe marudzi haana kufanana, vasati vatenga madhaimani, iwe unofanirwa kunzwisisa mhando dzemadhaimani.

Kutanga, zvinoenderana nekuumbwa kweparutivi

1. Zvisikwa zvakaumbwa madhaimani
Madhaimani anodhura pamusika anowanzoumbwa neakakombama pamusoro penguva yemamiriro ekunze ekunyanyisa kupisa uye kudzvanywa (kazhinji madhaimani anowanikwa ane makore mazana mashanu nemashanu emakore. Rudzi urwu rwemadhaimani rwakanyanya mukukosha nekuti hazviwanzo.

2. Madhaimani ekugadzira
Nekuvandudzwa kwesainzi uye tekinoroji, kune akawanda madhaimani emusika, uye vanhu vazhinji vanogona kuita kuti madhaimani kuburikidza negirazi, zircon, strontium titanate nezvimwe zvinhu, uye kukosha kwematanho akadai, uye kukosha kwemadhaimani anowanzove akaderera. Asi zvakakodzera kucherechedza kuti mamwe madhaimani aya anogadzira ari nani anotaridzika kupfuura zvemagetsi zvakaumbwa.

Chechipiri, maererano nedanho redhaimani 4C giredhi

1. Kurema
Maererano nehuremu hwedhaimani, iyo yakakura kurema kwedhaimani, iyo yakakosha madhaimani. Iyo unit inoshandiswa kuyera uremu hwe diamondi ndiyo carat (ct), uye imwe carat yakaenzana negiramu mbiri. Chatinowanzo fonera 10 mapoinzi uye makumi matatu emapoinzi anokamurwa kuita zvikamu zana, chimwe nechimwe chazvo ndechimwe chinhu chimwe, icho, mapoinzi mashanu ari 0.1 carats, makumi matatu ematanho 0.3 carats, zvichingodaro.

2. Ruvara
Madhaimani anokamurwa neruvara, izvo zvinoreva kudzika kweruvara pane mhando yemuvara pazasi. Zvinoenderana nekudzika kwerudzi rwedhaimani kuti uone mhando yedhaimani, kuswededza madhaimondi haina ruvara, iyo inounganidzwa. Kubva kuD giredhi madhaimani ekuti z grade madhaimani ari kuwana rima uye kusviba, GJ inenge isina ruvara, uye k-grade diamonds inorasikirwa kukosha kwavo pamwe chete.

3. Kujeka
Madhaimani akakamurwa nekujekeswa, ayo ari kunyatsochenesa diamondi. Kuchena kwedhaimani kunogona kucherechedzwa pasi pegumi-fold microscope, uye zvakanyanya kana kupfuura zvinokanganisa, nezvimwe, nezvimwe, zvakadzama kukosha, uye zvinotyisa. Zvinoenderana nekujeka kwemadhaimondi makuru akakamurwa kuita marudzi matanhatu, zvichiteerana fl, kana, vvs, vs, s, i.

4. Cheka
Govanisa madhaimani kubva kucheka, zvirinani kucheka, iyo kakawanda madhaimani inogona kuratidza mwenje kuti uwane chikamu chakakwana. Iyo yakajairika madhaimani akacheka maumbirwo memoyo ari moyo, mraba, oiri, kutenderera uye mutsipa. Pazviri izvi, madhaimani akakamurwa mumhando shanu: Ex, vg, g, zvakanaka uye murombo.

Chetatu, maererano nedare redhaimani reruvara

1, isina ruvara madhaimani
Mavara asina ruvara anoreva mhando yeisina ruvara, ingangoita isina ruvara, ine hukasha yemavheni madhaimondi, uye kuiswa kwemadhaimani madhaimani anotaurwa pamusoro apa maererano nekudzika kwemuvara kuti apatsanidzwe.

2. Marovere madhaimani
Chikonzero chekuumbwa kwemadhaimani ndeyekuti shanduko dzakavanzika mukati medhaimani dzinotungamira kune ruvara rwedhaimani, uye maererano nerudzi rwacho rwedhaimani, madhaimani akakamurwa kuita marudzi mashanu. Panyaya yemutengo, yakakamurwa madhaimani madhaimani madhaimani, madhaimani madhaimani, madhaimani madhaimani uye madhaimani madhaimani (kunze kwedhaimani dzakasarudzika).
