MARLII LAB was founded in 2023 with a commitment to blending elegance with sustainability in fine jewellery. Frustrated by the lack of ethical options in the market, the team established MARLII LAB in the heart of Adelaide to offer an alternative that prioritises environmental and social responsibility. Led by a team with over 9 years experience in fine jewellery, MARLII LAB is dedicated to redefining luxury jewellery. We are committed to using only lab-grown diamonds and responsibly sourced gold, ensuring that each piece is crafted with the highest ethical standards. Their vision is clear: to create beautiful, meaningful jewellery without compromising on sustainability.

At MARLII LAB, transparency and integrity are at the core of everything we do. Our diamonds and gemstones are cultivated in zero-emission laboratories, significantly reducing our carbon footprint. We work exclusively with suppliers certified by the Responsible Jewellery Council, ensuring that our gold is sourced responsibly and ethically. Proudly 100% made in Australia, we are committed to supporting local artisans and businesses.
