About Sam Tsia

Founded in New York City in 2015, Sam Tsia is a fine jewelry studio where each piece is designed and made by hand by founder Samantha Tsiagalis. Now working from her home studio in Lightning Ridge, Australia since 2023, Samantha is closely connected to the land and materials that inspire her work, including some of the world’s most extraordinary opals.

As a first-generation Greek American, her designs are guided by the effortless beauty and quiet elegance of the Greek Islands — a sensibility that values natural form, balance, and enduring quality. Every Sam Tsia piece reflects this philosophy, blending sculptural detail with a sense of ease and harmony.

Sam Tsia pieces are created in very small quantities, often as one-of-a-kind works that revolve around a specific center stone, and are intended to be collected and worn for a lifetime.

Commissioning a custom Sam Tsia piece is a personal and intimate process, centered on trust, craftsmanship, and intention. From sourcing rare stones to shaping each element by hand, the experience is designed to honor both the materials and the individual who will wear them.
