Clarity of Diamonds

A diamond’s clarity is determined by the degree to which it is free from naturally occurring inclusions, often called ‘nature’s fingerprints’.

The number, type, colour, size and position of the internal birthmarks can affect a diamond’s value.  However, many are invisible to the naked eye requiring magnification under a standard 10x magnification loupe before they become apparent.  The fewer inclusions, the rarer the stone and the higher its value.
