Maabara ya DEF Colour CVD almasi zinazokuzwa zinauzwa
CVD maabara mzima almasi Ukubwa
Karati ni kitengo cha uzito wa almasi.Carat mara nyingi huchanganyikiwa na saizi ingawa kwa kweli ni kipimo cha uzito.Karati 1 ni sawa na miligramu 200 au gramu 0.2.Kipimo kilicho hapa chini kinaonyesha uhusiano wa kawaida wa ukubwa kati ya almasi ya kuongeza uzito wa karati.Kumbuka kwamba ingawa vipimo vilivyo hapa chini ni vya kawaida, kila almasi inayokuzwa katika maabara ya CVD ni ya kipekee.
Rangi: DEF
Rangi ni rangi ya asili inayoonekana katika almasi iliyopandwa kwenye maabara ya CVD na haibadiliki kwa wakati.Maabara ya CVD isiyo na rangi ya almasi iliyokuzwa huruhusu mwanga mwingi kupita kuliko almasi ya rangi, ikitoa mng'ao zaidi na moto.Ikitenda kama mche, almasi hugawanya nuru katika wigo wa rangi na kuakisi mwanga huo kama miale ya rangi inayoitwa moto.
Uwazi: VVS-VS
Uwazi wa maabara ya CVD iliyokuzwa ya almasi inarejelea uwepo wa uchafu ndani na ndani ya jiwe.Wakati jiwe mbaya linatolewa kutoka kwa kina cha kaboni chini ya ardhi, chembe ndogo za vitu vya asili karibu kila wakati hunaswa ndani na huitwa inclusions.
Kata: EXCELLENT
Kata inahusu pembe na uwiano wa almasi.Kukatwa kwa almasi - umbo na kumaliza, kina na upana, usawa wa sehemu - huamua uzuri wake.Ustadi ambao almasi hukatwa huamua jinsi inavyoakisi na kurudisha nuru vizuri.
