4C Inbhe daoimeanan air fàs ann an obair-lann
Dath
Tha dath daoimeanan fàs Lab air a rangachadh ann an àrainneachd seallaidh àbhaisteach.
Soilleireachd
Soilleireachd ìrean 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 a dhearbhadh.
Carat cuideam
Is e a’ chiad ìre ann an rangachadh daoimeanan a chaidh fhàs ann an obair-lann 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.
