A Passion for Diamonds

At the heart of GS Diamonds is passion, founded by husband and wife, Julia and Tony, who for over 30 years have shared their love of diamonds and design. With an equally passionate team, including son Peter, who are committed to creating beautiful jewellery that women love to wear forever.


Every woman deserves diamonds, and GS Diamonds wants every woman to have the best. That is why Tony individually selects every diamond straight from the source, which is handcrafted with the latest technology in our Sydney studio to deliver the best quality and price.

Understanding that every woman is different, GS Diamonds offers choice; in diamonds, designs and customisation.

Nothing is too much trouble.

Nothing gives us greater joy than your happiness.

We want you to have the perfect diamond for you.
