4C Standar saka dhuwur meksa dhuwur suhu mirah
warna
Werna berlian suhu dhuwur tekanan dhuwur diklasifikasikake ing lingkungan tampilan standar. Gemologists nganalisa warna ing macem-macem warna D nganti Z kanthi berlian diselehake ing sisih, dideleng ing sisih, kanggo nggampangake tampilan netral.
kajelasan
Gelar kajelasan saka dhuwur meksa dhuwur suhu mirah miturut standar ditampa internasional ing 10X magnification, miturut visibilitas, ukuran, nomer, lokasi lan alam karakteristik internal lan lumahing ing magnification sing.
Cut
Gemologists sakabèhé takeran, pangukuran lan ngarepke facet dibandhingake karo pasinaon padhange, geni, scintillation lan pola kanggo nemtokake Cut Grade saka hpht dianggep mirah.
Bobot karat
Tahap pertama ing grading berlian suhu dhuwur tekanan dhuwur yaiku nimbang inten.Bobot karat minangka unit bobot standar kanggo watu permata.Grading Diamond nganti rong panggonan desimal kanggo njamin akurasi.
