The process of choosing the right diamond starts with the point in the 4 Cs - Carat, Cut, clarity and color. All this has been taken into account throughout the process when the diamonds are negotiated worldwide. GIA is the largest organization established in 1931 that authorizes diamonds, colored stones, and pearls. An official no-profit institute, GIA is also the leading source of knowledge, standards, and education in precious stones and jewelry. Whether you want to buy loose diamonds or you buy finished diamond jewelry, take a look at the certificate included and get the quality validation you need. No matter how beautiful a diamond may look or how much it reflects, you cannot see its true quality. The 4Cs would give you the necessary information about the quality you need, so you can make an informed purchase.
