A ring that evokes the happiness of love and partnership is even more joyful when you know that it was sustainably sourced and mindfully produced. From our mission to our unique jewelry designs, everything at Brilliant Earth is held to exceptional standards.

Our engagement ring settings are made-to-order with each one handcrafted for your selected center gem’s unique characteristics to ensure the high quality of the finished piece.
As part of our commitment to protecting the planet, Brilliant Earth is Carbonfree®. We calculated our carbon footprint by assessing the direct emissions of our energy use, including packaging, shipping, and employee travel and commuting.
