In 2003, RTD's India office started implementing an initiative to raise standards among its customers - diamond and jewellery manufacturing firms - regarding the quality of their work and the management of issues relating to environment, health, safety, and social responsibility. Called the Business Excellence Model (BEM), it is a set of standards which can be used for accreditation of customers who achieve certain standards.

The "model" covers health and safety, social responsibility, environmental regulation and operational quality. It focuses on issues such as the use of personal protective equipment, hygiene and housekeeping, paying statutory minimum wages, employing no child labour, providing employee facilities, and preventing pollution. Assuring operational quality is centred on having a customer focus and customer satisfaction feedback.

KPMG in India has been awarded the responsibility of auditing RTD's customer businesses against the standards developed. Each factory owned by a customer will be audited. Once standards are met, a certificate of accreditation will be awarded. This should help customers in their marketing activities as well as providing assurance to RTD that its products are processed by firms operating to acceptable standards of social responsibility.
