Our Story


In 1976, Wolfgang Schwantes opened the doors of Xennox Diamonds, with a vision of bringing the world's finest jewellery to Brisbane. His passion and commitment to excellence laid the foundation for the Xennox brand.

In the family

Wolfgang's son, Karl, inherited his father's passion for jewellery and joined the family business. Under his leadership, Xennox has grown to become one of Australia's premier jewellery destinations.


Today, Xennox Diamonds continues to be a family-run business, with a team of passionate and knowledgeable experts who are dedicated to providing the highest quality service and craftsmanship.


With a focus on innovation and excellence, Xennox Diamonds is committed to staying at the forefront of the industry. We are constantly exploring new technologies and designs to bring our clients the best possible experience and products.
