Maabara ya jumla iliyoundwa almasi EX VG cvd almasi kununua online
Uzito wa Carat
Sehemu ya uzani ya almasi iliyotengenezwa na maabara ya CVD 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.

Daraja la Rangi
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.

Kata Daraja
Ubora wa kukata huathiri moja kwa moja uzuri wa almasi iliyoundwa na maabara ya CVD, 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.
