4C Kiwango cha almasi zinazokuzwa katika maabara ya hpht
Hpht maabara mzima almasi Rangi
Rangi ya almasi hupangwa katika mazingira sanifu ya utazamaji.Wataalamu wa madini huchanganua rangi katika safu ya rangi ya D hadi Z huku almasi ikiwekwa juu chini, ikitazamwa kupitia ubavu, ili kuwezesha mwonekano wa upande wowote.
Maabara ya Hpht iliyokuzwa almasi Uwazi
Huainisha uwazi kulingana na viwango vinavyokubalika kimataifa katika ukuzaji wa 10X, kulingana na mwonekano, saizi, nambari, eneo na asili ya sifa za ndani na za uso katika ukuzaji huo.
Hpht maabara mzima almasi Kata
Wanajimu kwa ujumla uwiano, vipimo na pembe za sehemu hulinganishwa na tafiti za mwangaza, moto, ukoleaji na muundo ili kubainisha Daraja la Kata.
Hpht maabara mzima almasi Carat
Hatua ya kwanza katika kupanga almasi ni kupima almasi.Uzito wa Carat ni kitengo cha uzito cha kawaida cha vito.Uwekaji alama wa almasi ni sehemu mbili za desimali ili kuhakikisha usahihi.
