Established in Sydney in 1899 Percy Marks remains a family owned and run business and for over a century we have shared our passion for the finest diamonds and gemstones with clients from Australia and around the world.

From our heritage as the first purveyor of Australian Black Opals, our expertise extends to all the rare and magnificent gems that are unique to Australia – from lustrous South Sea Pearls to the rare and most highly prized Argyle pink diamonds our collections feature an extensive range of gemstones and fully certified diamonds, each individually selected for their outstanding beauty and quality.

Having the fully qualified jewellers at Percy Marks regularly inspect your jewellery is your best maintenance programme.

If you have jewellery sitting in a drawer that you no longer wear because its too small, not your style, or broken bring it into Percy Marks and let our team help you create something new that you will love to wear.

From pearl rethreading to redesigning an existing piece in a more contemporary manner we would love to work with you. Free estimates can be provided in store for all work required.
