Our Story

Third generation family jewellers

J&C Manufacturing Jewellers is a family owned and operated workshop in Semaphore, well respected by local and interstate clients as one of the finest manufacturing jewellers in Adelaide.

Owner and jeweller Greg began his trade in 1981 and brings decades of experience in design, manufacture and repairs. He has trained a number of jewellers over his career, most recently his son Zachary, a third generation jeweller and finalist in the 2010 JAA Australian Jewellery Design Awards. Alongside Kerry, also a third generation jeweller, the bench carries more than a century of combined craft.

From the smallest repair to the most intricate commission, quality, attention to detail and finish are paramount. Greg, his wife Donna and the team will attend to every jewellery need, and help you choose that special piece from our in-store range.

What We Do

Everything, made and maintained on-site

From a first sketch to a yearly clean, our workshop handles the whole life of a piece, so it stays as it should for the people who wear it.

Custom Design

A one-of-a-kind piece designed around your style, needs and budget. From engagement and wedding rings to special-occasion jewellery, we guide you through design, materials, gemstones and manufacture.

Repairs & Restoration

Bring damaged, broken or worn jewellery back to life. Our on-site workshop handles repairs and restorations with care, quality workmanship and a fine eye for detail.

Remodelling & Remakes

Turn old, unworn or sentimental jewellery into something new. We reuse existing gold and gemstones, source additional stones, and shape a fresh design from treasured pieces.

Valuations

We arrange professional independent valuations for insurance, probate, estate purposes, private sale, second-hand replacement value, or simple peace of mind.

Care & Cleaning

Keep your jewellery sparkling with professional cleaning, annual inspections, and honest advice on the care products that suit your pieces.

Diamond Sourcing

As Accredited Antwerp Diamond Brokers, we source high-quality diamonds in the exact size, shape, quality and price you are looking for, often at a substantial saving.
