An evening dedicated to sapphires.

We were delighted to welcome Joanna Hardy and Jessica Diamond to Cox & Power for a fascinating conversation exploring the remarkable world of sapphires—from their geological origins and extraordinary colours to the stories and craftsmanship behind these exceptional gemstones.

Thank you to everyone who joined us for an inspiring evening of conversation, learning and a closer look at some truly remarkable stones.

On the final day of Seongmin Kim’s residency and exhibition at Cox & Power, we are delighted to introduce Stillness.

Created during her time in the gallery, the necklace features dove-grey freshwater pearls, hand-carved white mother of pearl, and a beautifully carved mother of pearl clasp.

Bringing together many of the themes explored throughout the residency, Stillness rewards close observation, revealing the subtle beauty of natural materials and the attention to detail that defines Seongmin’s practice.

Thank you to everyone who has visited the exhibition, spent time with the work, and supported Seongmin’s residency over the past weeks.

Every detail, from the halo setting to the polished platinum finish, was carefully considered with our client.

When you commission a piece with us, you work directly with our team of dedicated craftspeople to design something custom-made and totally unique, just for you.
