Jewellery Studio & Workshop Services

We offer a range of jewellery services at our Hervey Bay studio, from jewellery and watch repairs to custom bespoke designs. Our team is known for designing and creating unique and innovative designs, with a focus on old-fashioned customer service.

Knowing that jewellery can hold a significant amount of sentimental value to the wearer, we believe no job is too small. From resizing a ring, to a simple chain repair, we treat every piece we work on as if it were our own.
