Cosimo.

Cosimo Jewellery is a custom design and repair studio in Five Dock, run by its namesake jeweller Cosimo, who works directly with clients on both new commissions and restoration work. Much of the shop's reputation comes from hands-on repair and adjustment work on existing pieces. Customers describe bringing in a small diamond ring for repair and being delighted with the result, and one client had a diamond ring adjusted and returned the very next day rather than having to leave it behind for a longer trip. Reviewers consistently describe the finish on repaired pieces as flawless, with close attention paid to matching the original craftsmanship. Alongside repairs, Cosimo designs and hand-crafts custom pieces from scratch, including engagement rings and wedding bands, and has taken on more unusual commissions such as a bespoke set of rose gold drumsticks for a customer. His website also lists a watches category among the jewellery on offer, alongside dedicated engagement ring, gemstone and custom design sections. Clients describe Cosimo as a true craftsman who listens carefully to what they want before creating or repairing a piece, with a process they call professional, easy and enjoyable from consultation through to collection. The studio's ability to turn around adjustments quickly, sometimes overnight, has made it a go-to for Sydney's inner west when a piece needs fixing in a hurry.
