The Argyle Dreaming necklace features an interchangeable 3.55-carat white Argyle diamond centre stone, which can be switched with the ring’s champagne diamond centre stone. The piece also includes blue and yellow Argyle diamonds as accents.

Comprising of 673 pink, white, yellow, blue and champagne Argyle diamonds and 237 grams of Rio Tinto gold, Calleija's Argyle Dreaming set of jewellery took over 800 hours to create. Above is a close up of the ring with interchangeable center stone.
