Diamaint saothraithe saotharlainne Hpht Dath
Déantar dath an diamaint a ghrádú i dtimpeallacht chaighdeánaithe amhairc.Déanann geimeolaithe anailís ar dhath sa raon datha D go Z agus cuirtear an diamant bun os cionn, amharc tríd an taobh, chun radharc neodrach a éascú.
Diamaint saothraithe saotharlainne Hpht Soiléireacht
Gráid soiléireachta de réir caighdeáin a nglactar leo go hidirnáisiúnta ag formhéadú 10X, de réir infheictheacht, méid, líon, suíomh agus nádúr na saintréithe inmheánacha agus dromchla ag an méadú sin.
Diamaint saothraithe saotharlainne Hpht Gearr
Déantar comhréireanna foriomlána, tomhais agus uillinneacha gné na gemologists a chur i gcomparáid le staidéir ar ghile, tine, scintillation agus patrún chun an Grád Gearrtha a chinneadh.
Diamaint saothraithe Hpht lab Carat
Is é an chéad chéim i ngrádú diamant ná an diamant a mheá.Is é meáchan carat an t-aonad meáchain caighdeánach do chlocha geama.Tá grádú diamant go dtí dhá ionad dheachúlacha chun cruinneas a chinntiú.
