At DECCLA, we're doing things differently.

LABS by DECCLA is our inaugural venture into modern luxury, where world-class craftsmanship meets sustainability and transparency.

Our lab-grown diamonds are indistinguishable from nature's variants and guarantee the complete abolition of conflict diamonds within our collection.

Our partnered laboratories produce exceptional diamonds while upholding favourable working conditions and reducing carbon emissions.

With a minimised carbon footprint and zero traceability concerns, we believe luxury can—and should—come with a conscience.

Each ring is handcrafted with over a decade of honed artisanal experience, creating the perfect setting for your uniquely selected gemstone.

We curate the finest Hearts & Arrows and Triple Excellent diamonds, making an unprecedented selection accessible.

Every ring we craft is as unique as the love it symbolises. Our engagement rings combine personal touches with unrivaled materials, hand-finished in 18K gold or platinum, built to the highest standards of resilience.

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

From our headquarters in Sydney, we collaborate with a global network of artisans and diamond cutters who uphold unwavering standards of excellence. All our diamonds are certified by GIA or IGI with physical certificates provided.
