Whether the diamond is white, black, or colored, all the diamonds of the French luxury jewelry house are selected in respect of the Kimberley process.
Our diamonds do not come from conflict zones and are chosen according to rigorous assessment criteria.
Each D.Bachet jewel set with a white or colored diamond is chosen for its exceptional character under the 4Cs criteria established by the GIA (Gemological Institute of America), reputed for its rigor to the highest level in the diamond’s selection. We select only the top categories of the 4Cs.
As a result of its opacity, the 4Cs standards for assessing the quality of white diamonds and colored diamonds do not apply for black diamonds.

We use the quality scale going from A, AA to AAA, based on an assessment of the diamond's cut, polish and symmetry. When these three criteria are excellent, they are graded AAA.
