About Us


With roots originally from Russia, the founders of Arnold & Co. have always had a passion for precious metals and gems. Qualified geologists head up the team, who are trained to source and select stones, and also maintain them. Years of experience operating jewellery stores across the globe and unparalleled industry knowledge makes Arnold & Co. shine in their professional and personal delivery of quality jewellery.

Today, Arnold & Co. and its sister store, Diamond Design, offer some of the most beautifully designed jewellery pieces across Canberra and Sydney. Both stores ensure all of their diamonds are ethically sourced both locally and internationally, and are conflict-free, certified diamonds and precious metals.

Known for their unwavering commitment to producing only the highest quality of jewellery, Arnold & Co. specialise in working closely with their clients to create the perfect piece. With a master jeweller, two gemmologists and an in-house designer in their team, they offer complete personalised service from start to finish.

Securing their position as Canberra’s premium jewellery specialist, Arnold & Co. also offer their clients the opportunity to design their own pieces in the Arnold and Co. Design Studio. From hand-selecting a diamond, to working with a designer to create a truly personalised item that speaks to the individual. Arnold & Co. brings each piece to life with their 360 virtual design program; turning jewellery dreams into reality.

For more than a decade, the team at Arnold & Co. have been crafting beautiful, timeless jewellery for their clients. More than just a jewellery store, Arnold & Co. create bespoke pieces that tell a story and uniquely connect with a client. Based on an understanding that no two gems are the same, Arnold & Co. work on the philosophy that no two clients are the same, therefore each piece created is unlike any other. It has its own presence, personality and meaning.
