The strict screening and classification of the diamonds to be used in our collections reflect the high level of qualitative research taking place at 3ND, which is out of the ordinary. 3ND, indeed, only ever selects VVS1 diamonds for its glasses. Each and every stone is set manually and 3ND sets itself apart from the symmetrical crystal setting, that is typically used in most eyewear and accessory collections, by offering the innovative snow-setting technique, which makes each model unique and one of a kind.
