For Diane Petheriotis, jewellery has always been about more than the finished piece. It is about craftsmanship, individuality, and creating something with a story behind it.

Beginning her journey in Kelowna, British Columbia, Diane’s passion for fine jewellery has taken her from Vancouver to New York and Italy, giving her invaluable insight into the world of luxury jewellery. Along the way, she gained behind-the-scenes exposure to renowned houses including Harry Winston and Mikimoto, while exploring the traditions and artistry of jewellery design in Italy.

Today, Diane brings that experience home to The Rock Box Jewellery Studio, creating and curating distinctive fine jewellery with a deeply personal approach. From custom jewellery and one-of-a-kind designs to thoughtfully selected pieces, her work combines timeless craftsmanship with a style that feels individual, expressive, and made to be lived in.

Designed with intention. Made to tell your story.
