Just as a few factors influence our decisions in everyday life, so does the 4Cs influences how much every stone is and should be priced.

It is obvious – a perfectly unblemished, flawless, and well-proportioned stone will cost a lot more than a flawed diamond, even if showcasing the same carat weight.

A factor that is responsible for depreciating value and price of certain diamond shapes while creating a monopoly of demand for others is the brilliance of a diamond.

Diamond Shape –What Is the Most Expensive?
