4C Inbhe daoimeanan fàs lab hpht
Hpht lab air fàs daoimeanan Dath
Tha dath daoimean air a rangachadh ann an àrainneachd amhairc àbhaisteach.
Hpht lab air fàs daoimeanan 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.
Hpht lab fàs daoimeanan 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.
Hpht lab air fàs daoimeanan Carat
Is e a’ chiad ìre ann an rangachadh daoimean 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.
