Lab Grosir nggawe berlian EX VG cvd berlian tuku online
Bobot karat
Unit bobot saka lab CVD digawe berlian yaiku karat (ct), 1 karat = 100 poin = 0,2 gram
Nalika referensi 4C liyane padha, sing luwih bobot saka mirah, sing luwih dhuwur nilai
Tabel iki mung digunakake minangka referensi kanggo mbandhingake ukuran karat sing beda-beda, sing bisa uga beda karo ukuran nyata.
Kelas Warna
Grading kajelasan adhedhasar karakteristik internal berlian kaya sing diamati ing perbesaran 10x, kanthi inklusi sing luwih sithik nggawe inten luwih langka.

Cut Grade
Kualitas potong langsung mengaruhi kecemerlangan lab CVD digawe berlian,VG ing ndhuwur potongan berlian, geni berlian luwih jelas.Disaranake milih berlian kanthi 3EXcut kanthi efek cahya wolung ati lan wolung panah, sing apik banget.
