Profile.

MARLII LAB was established in Adelaide in 2022 by Lucinda and her partner Giacomo, with a simple mission: to create Modern Heirlooms — pieces that feel personal now, and priceless later. We design fine jewellery that carries meaning, made to be worn often, loved deeply, and one day passed on to the next generation.

At the heart of MARLII LAB is time well spent. Lucinda and Giacomo work closely with each client, building genuine relationships and designing through conversation — getting to know your style, your life, and the story you want your piece to hold. It’s warm, intimate, and quietly special: a bespoke experience that feels relaxed, yet undeniably luxurious.

Our aesthetic nods to the past while living firmly in the present — antique and old-world cuts, redefined in refined antique settings with a contemporary edge. The result is jewellery that feels collected, not manufactured: future heirlooms created with care, intention, and a little bit of romance.
