In 2005, we launched Brilliant Earth to raise the standards in the jewelry industry while creating beautiful fine jewelry that is different in every way – how it’s made, how it’s sold, how it’s sourced and crafted, and how it gives back. As a result, we go beyond current industry practices for sourcing, use recycled precious metals to minimize our environmental footprint, and support environmental and social causes through our giving back initiatives. Or Mission is to cultivate a more transparent, sustainable, compassionate, and inclusive jewelry industry. Our Mission and ESG Goals are underpinned by our foundational pillars: We believe that demonstrating transparency, through ethical business practices and governance, and enforcing rigorous protocols for sourcing environmentally and socially responsible materials are key to driving change in our industry. Our products are designed to be loved for generations, and we seek to reduce our environmental footprint by keeping our jewelry circular and embedding environmental sustainability throughout our operations and value chain. We seek ways to create lasting impact, not just in our own value chain and customer communities but also across artisanal small scale mining communities where gemstones and precious metals are sourced. We are committed to creating a representative jewelry industry through our unique products and inclusive experiences for customers, and through a company culture that emphasizes equitable recruiting practices and invests in our diverse employee base.
