At Diamond Lab, we specialise in elegant, ethical engagement rings that combine high-end craftsmanship with modern values. Our radiant cut lab diamond solitaire rings offer bold brilliance, clean symmetry, and minimalist beauty—making them an exceptional choice for couples in Perth.
The radiant cut is beloved for its square or rectangular shape with trimmed corners and a brilliant-cut facet pattern. It offers the fire of a round diamond with the shape of an emerald, giving you the best of both worlds: maximum sparkle with a modern silhouette.
When paired with a solitaire setting, the radiant diamond becomes the centrepiece of attention. This style is ideal for those who appreciate timeless minimalism—perfect for showcasing your stone without distraction. Whether you’re proposing along the Perth foreshore or planning a celebration in the hills, a radiant solitaire ring offers undeniable impact.
Our lab-grown diamonds are eco-friendly and ethically sourced, offering the same brilliance, durability, and quality as mined diamonds without the ethical baggage. All our stones are IGI or GIA certified and selected for their optimal cut, colour, and clarity.
Clients from Perth suburbs such as Nedlands, Leederville, and South Perth choose Diamond Lab for our high-touch service, bespoke design process, and luxury finish. Every ring is made to order with the option to fully customise: select your metal (14k/18k gold or platinum), band thickness, setting style, and diamond size to create a piece as unique as your love story.
We also offer virtual consultations, custom sketches, and CAD renderings to ensure every detail aligns with your vision. Our Perth showroom is open by appointment, or you can design from the comfort of your home.
As Australia’s most trusted lab diamond jeweller, we’re proud to bring radiant brilliance to couples across Perth—ethically, beautifully, and with heartfelt craftsmanship.
