Introducing the Octo Ring.

A contemporary interpretation of the suction pads on an octopus, encircling the finger in diamonds of varying size. Representing the beautiful, uneven balance of nature, the diamonds are placed in an organic rhythm without repetition.

Expressed in 18k recycled solid gold with natural, F/VS diamonds between 1.540-1.870 carats.

Introducing the Diamond Entropy Ring.

Entropy: the countless ways a system can be arranged, observed here in the way water droplets gather and the endless formations they create. In this signet ring, no two diamond is the same size or height. The composition appears almost accidental, yet each stone is precisely placed, relying on the next, held together in a delicate equilibrium.

Interpreted in 18K recycled gold with 49 round, natural F/VS diamonds (1.10cts).

aestival | adjective | \ˈes-tə-vəl\
Of or belonging to the summer; appearing or occurring in summer. From Latin aestivalis, from aestas, summer.

Introducing the Aestival collection. A study of summer in bubbles and droplets. Of the close formations they create in boiling water, the way they gather on skin in the heat and cluster in beads on a cold glass. An exploration of casual opulence, if such a thing exists. Photographed in New York City during a heatwave.
