A diamond's clarity grade assesses how free a diamond is of inclusions and imperfections.
Note: Some inclusions - tiny crystals and other features - do not affect a diamond's clarity and value. Sometimes diamonds with a low clarity grade are therefore still "eye clean". However, other inclusions can affect not only the beauty of a diamond, but also its structural character.
A diamond being conflict free includes all sustainable social and ecological aspects within the value chain. The standard excludes inhumane working conditions, child labour, the financing of civil wars and environmentally harmful practices such as mining or the use of coal-fired power. Likewise, under this standard, the diamonds are not enhanced by radioactivity.
