Goldsmith & Diamond Setter

Born in Adelaide, Maurice Lorenz began his journey into the world of jewellery in 1981. He apprenticed under the expert guidance of his German-born father, Manfred Lorenz, a Master Jeweller and one of the founding members of the Goldsmith’s Guild of South Australia. From his father, Maurice learned traditional goldsmithing techniques, skills he continues to utilise and perfect to this day.

Maurice also specialises in Optical Diamond Setting, a precise and intricate craft. He had the privilege of refining his skills in Antwerp, Belgium, under the tutelage of Alexandre Sidorov, a world-renowned master of Diamond Setting. It was in this diamond capital that Maurice honed his expertise in the European standard of stone setting, elevating his craftsmanship to an international level.

Committed to continuous professional development, Maurice integrates advanced techniques to enhance the quality of his work. As a Full Member of the Gold and Silversmiths Guild of Australia, he upholds the highest standards in jewellery manufacture.

Maurice finds great satisfaction in listening to people’s stories and translating those special memories into wearable pieces of art. His passion for creating meaningful jewellery ensures that each piece is not only beautifully crafted but also deeply personal and enduring.
