The Harmonic collection is a collaborative capsule launched in partnership with world renowned diamond mine, Rio Tinto, and their Diamonds With a Story initiative. With a focus on sustainability in design and business practice, Sandy Leong was honored by Rio Tinto for the second year in a row for her work highlighting the importance of tracing diamonds- and other materials- back to their origins. 

The Harmonic collection was designed to symbolize vibrations and sound waves. Each note and curve is constructed in 18 karat recycled gold and ethically sourced diamonds that have been mined responsibly and transparently from Rio Tinto's Argyle diamond mine in Western Australia.
