Our commitment is a part of a global campaign The Rapaport Pledge. The pledge allows socially responsible consumers, jewelers and their suppliers to publicly identify themselves on the www.ethicalpledge.com website and make the following commitments:

  1. Commit - Take responsibility for the legitimacy of the products that you buy and sell.
  2. Investigate - Proactively and reasonably investigate your supply chain, or ask your jeweler if they have investigated their supply chain.
  3. Know your goods - Refuse to buy or sell products you know or have reason to know have been involved in unethical activity.
  4. Take a stand - Require your jewelers and suppliers to provide a written statement affirming that they have reasonably investigated the supply chain of the products they sell.
