VVS1 VVS2 VS1 VS2 cvd maabara ya almasi iliyokuzwa na kuthibitishwa
maabara mzima almasi gia kuthibitishwa Carat uzito
Sehemu ya uzito ya almasi iliyokuzwa katika maabara ni karati (ct), karati 1= pointi 100 = gramu 0.2
Wakati marejeleo mengine ya 4C yanafanana, kadiri uzito wa almasi unavyoongezeka, ndivyo thamani inavyokuwa juu
Jedwali hili linatumika tu kama marejeleo ya kulinganisha saizi tofauti za karati, ambazo zinaweza kuwa tofauti na saizi halisi.
maabara mzima almasi gia kuthibitishwa Rangi
Rangi za almasi zilizokuzwa katika maabara zimeorodheshwa kama D E F G H I JK L M N
maabara mzima almasi gia kuthibitishwa uwazi
Uwekaji alama wa uwazi unatokana na sifa za ndani za almasi kama inavyozingatiwa chini ya ukuzaji wa 10x, na mijumuisho michache inayofanya almasi kuwa adimu.
maabara mzima almasi gia kuthibitishwa Kata
Ubora wa kukata huathiri moja kwa moja uzuri wa almasi, VG juu ya kukata almasi, moto wa almasi ni dhahiri zaidi.Inashauriwa kuchagua almasi na 3EXcut na mioyo nane na athari ya mwanga ya mishale nane, ambayo ni nzuri sana.
