The Guide to Diamonds – the 4Cs

The International Gemological Institute (IGI), a globally recognized institution, leading labgrown diamond grading, certifies a diamond’s quality by using the international recognized standards, also known as the 4Cs: Color, Clarity, Cut and Carat.

In keeping with BA.SG’s dedication to quality, we examine the selected stone’s certification accurately so that all selected stones meets the standard, before moving on to another level of strict and professional physical inspections
