LABS BY DECCLA
REDEFINING FINE JEWELLERY FOR THE CONSCIOUS ERA

At DECCLA, we're pioneering a new approach to luxury.

LABS by DECCLA marks our first step into modern luxury— where craftsmanship embraces transparency, and innovation drives sustainability.

A THOUGHTFUL EVOLUTION IN FINE JEWELLERY

LABS by DECCLA offers an innovative take on diamonds, offering sustainability without the traditional price markup.

Our lab-grown gemstones are indistinguishable from nature's finest but come with the peace of mind that only ethical sourcing can provide.

From origin to the final piece, our diamonds carry a story of transparency and responsibility. With a minimised carbon footprint and zero traceability concerns, we believe that luxury can—and should—come with a conscience.

YOUR STORY, OUR CRAFTSMANSHIP

Every piece we create reflects meticulous craftsmanship and attention to detail. Our foundation is built on an exceptional curation of finest-tier Hearts & Arrows and Triple Excellent diamonds, offering an unprecedented selection now made accessible.

We ensure that every ring we craft is as unique as the love it symbolises. Our engagement rings combine personal touches with the unrivalled calibre of materials, hand-finished in 18K Gold or Platinum, and built to the highest standards of resilience.

We understand the significance of your engagement and relentlessly strive to honour your moment with a seamless journey—from design to doorstep delivery.

A GLOBAL CONNECTION

From our headquarters in Sydney, we collaborate with a world network of artisans who uphold the same unwavering standards of excellence. With the support of renowned certification bodies such as GIA and IGI, we guarantee that every diamond adheres to the most rigorous benchmarks of quality and craftsmanship.
