About Us

Since 1898, when George William Cox opened the doors of our first watchmaker and jewellery store on Hindley street, G.W. Cox has been an integral part of the Adelaide cityscape. Now situated in the bustling Rundle Mall, G.W. Cox – My Jeweller has established an enduring reputation, with decades of experience in dealing with the sophisticated and individualised requirements of each generation of G.W. Cox customers. Over the years, we have become a household name and grown into a brand associated with trust, exceptional quality and joy.

In order to provide the highest level of service, we offer our customers practical advice, value for money and distinctive jewellery with enduring style. We design many of our own signature pieces and source the best quality stones and materials, offering unparalleled quality and choice, customised to the individual’s taste and budget.

Relationship Built on Trust

Making the decision to get married, proposing and selecting that perfect engagement ring is an exciting time in a couple’s relationship, but we also understand that it can be stressful. For many people, selecting an engagement ring is the first time they step inside a jewellery store. It is also the start of a lifelong relationship, starting with the engagement ring, followed by the wedding band, and then the eternity ring.

Over a lifetime, there will be countless opportunities to buy jewellery. That’s why it is important to develop a relationship with your jeweller. One you can trust, and who will be there for you for your entire journey, providing you with the best advice, and understand what it is that you are looking for, because they know you too.

When you purchase from G.W. Cox – My Jeweller, you are purchasing our family history, passion and experience. With that expertise comes loyalty, and an assurance that we are with you for life. After all, diamonds are forever, and that’s how long we promise to care for you and your jewellery.

Our Forever Promise

To maximise the life of the jewellery, we offer you the G.W. Cox – My Jeweller Forever Promise. We invite you to return to our store each year for us to assess your jewellery. We will provide advice on any repairs that need to be done and if no repairs are required, we will professionally clean and polish your jewellery so that you can wear it with confidence. The cleaning and assessing is our gift to you. You may be asked for proof of purchase, so please keep your receipt. We try to offer this service while you wait, but reserve the right to complete it within three days if we are unable to assist straight away.

Naturally, any repairs required as a result of a faulty product will be no charge as under Australian Consumer Law. For other repairs identified (usually from wear and tear), we will quote to repair. Loss of diamonds, gemstones or any other parts of your piece are not covered unless such a loss was caused by a defect in workmanship and/or materials without any undue stress or damage. Our jewellery is covered for the life of the piece; however, this will vary depending on the product. Taking advantage of Our Forever Promise will ensure that you get the best out of your jewellery.

Our Heritage

Still owned and operated by the Cox family today, G.W. Cox – My Jeweller is a fourthgeneration business and Adelaide’s oldest family jeweller. From the first store on Hindley street, G.W.’s son Cecil moved it to Rundle Street opposite the historic Beehive Corner. But when he died prematurely at 52, his son Gerald – Jon’s father - was forced to move it back to Hindley Street. It was here that he steered the business to create the real foundations of today’s business. In 1966, Gerald bought the current shop at 99 Rundle street and over the years, the business has become less of a watchmaker and more of a specialist in diamond rings and gold jewellery.

With Jon at the helm, we understand that today’s customers are more sophisticated, but and their tastes have become more discerning. In order to provide these customers with the highest level of service, we take the time to get to know our customers, understand what is important to them and aim to deliver the best value for their money. These have always been the G.W. Cox family values, but in today’s fast-paced world, true personalised service is rare and therefore more important.

Whatever your requirements or desires, our Adelaide-based jewellery experts can help you to find the perfect fit. Our mission is to offer you an unforgettable experience, one that will remain with you forever. We know that when choosing your first piece of diamond jewellery, an engagement ring or special anniversary piece, expertise and trust are paramount. G.W. Cox – My Jeweller will be with you every step of the way.
