While Blue Nile adheres to the Kimberley Process and provides conflict-free diamonds, their transparency regarding broader environmental practices and labor conditions in their supply chain could be improved. They have made commitments to responsible sourcing but lack comprehensive public reporting on their environmental impact and social responsibility initiatives. Their recycled materials usage and carbon reduction strategies are not clearly communicated, though they have taken steps to ensure ethical diamond sourcing.
