4C Inbhe daoimeanan fàs lab hpht
Dath
Tha dath daoimeanan air a làimhseachadh le hpht air a rangachadh ann an àrainneachd seallaidh àbhaisteach.
Soilleireachd
Soilleireachd ìrean de daoimeanan air an làimhseachadh le hpht a rèir inbhean ris an deach gabhail gu h-eadar-nàiseanta aig meudachadh 10X, a rèir faicsinneachd, meud, àireamh, àite agus nàdar feartan a-staigh agus uachdar aig an àrdachadh sin.
Gearr
Bithear a’ dèanamh coimeas eadar cuibhreannan iomlan gemologists, tomhasan agus ceàrnan aghaidh le sgrùdaidhean air soilleireachd, teine, spealadh agus pàtran gus an ìre gearraidh de na daoimeanan air an làimhseachadh le hpht a dhearbhadh.
Carat cuideam
Is e a’ chiad ìre ann an rangachadh daoimeanan air an làimhseachadh le hpht cuideam an daoimean.Is e cuideam carat an aonad cuideam àbhaisteach airson leacan-uaighe.Tha rangachadh daoimean gu dà ionad deicheach gus dèanamh cinnteach à cruinneas.
