Diamond quality standard "4C"
"4C" is an international standard for evaluating the quality of cut jewelery diamonds, established by the Gemological Institute of America (GIA). It is evaluated from the four points of color (color), transparency (clarity), weight (carat), and polishing (cut), and is abbreviated as "4C" from each acronym. This 4C is described in the diamond "certificate".
Custom-made is also available
You can choose the diamond with the certificate by yourself and make it with the posted design (product with the "order reform compatible design" mark) or the original design from scratch. ..
