The world’s most beautiful diamonds are those that are sourced in a way that respects the planet and the people who live on it. Over the years, we’ve taken extensive steps to ensure that the Ideal Cut melee diamonds we produce are beautiful in every way. We enjoy end to end control of our supply channel – sourcing the rough ourselves, operating our own production facilities, and selling directly to custom jewelers and jewelry manufacturers without involving any middlemen or third parties.
Now we’ve taken the next step and achieved RJC Certification. The Responsible Jewellery Council helps companies of all sizes, throughout the jewelry supply chain meet the rising ethical demands of peers, consumers, financial institutions, and civil society. Our certification means that we follow the RJC “Code of Practices”, a set of standards that pertain to human rights, environmental concerns, and other ethical concerns associated with fine jewelry production. It is through responsible sourcing and supply chain due diligence that the entire jewelry industry can improve, and we’re very proud to be part of this movement.
Demands for Ethical Diamonds are Changing the Jewelry Industry
Grunberger Diamonds is the world’s largest producer of Ideal Cut Melee Diamonds. This means the stones we deal in are very, very small. Given the size of our product, why do we care so much about how it’s produced?
First and foremost, we care because it’s the right thing to do. In this world, we are always faced with the opportunity to make choices. From our earliest beginnings in the 1930’s to the present day, we have always strived to run our business in the most ethical way. The reason we maintain end-to-end control of our diamonds is to eliminate risk to our customers, lower costs, and ensure a higher degree of quality control. We want our customers to be magnificently proud of the jewelry they create using our melee diamonds. That’s only possible when they know the diamonds are sourced responsibly.
RJC Certification also reinforces the value of real diamonds, which is increasingly important as lab-grown stones gain market share. To learn more about RJC certification, visit: https://www.responsiblejewellery.com/
