Celebrate your journey together with a lab diamond three stone oval engagement ring—one of the most meaningful and luxurious choices for modern couples in Perth. At Diamond Lab, we combine ethical innovation with timeless design to bring you handcrafted rings that reflect your love story.
The three stone setting has long been a symbol of your relationship's past, present, and future. When centred with a graceful oval diamond, the design becomes even more striking—elongating the finger and catching light from every angle. The side stones (usually round, pear, or trapezoid cuts) add dimension and brilliance, enhancing the beauty of the centrepiece without overpowering it.
Our lab-grown diamonds are created in controlled environments that mimic Earth’s natural process—delivering the same optical and chemical properties as mined diamonds but with zero ethical compromises. All of our stones are certified and selected for superior cut, colour, and clarity.
For clients in Perth—from the coastal views of Cottesloe to the urban elegance of Claremont—Diamond Lab offers both luxury and peace of mind. Every three stone ring is fully customisable: select your side stone shape, metal (white, yellow, rose gold, or platinum), setting style, and total carat weight.
The three stone oval design offers a bold and romantic look that works beautifully for proposals, anniversaries, or vow renewals. Whether you're after a classic prong-set arrangement or a contemporary low-profile silhouette, our team will guide you through each detail.
We offer virtual consultations, custom sketches, and detailed CAD renders to ensure your vision comes to life. You can also explore previous creations or start completely from scratch with our in-house jewellers.
As Australia’s leading lab diamond jeweller, Diamond Lab is proud to serve Perth with exceptional craftsmanship, sustainable values, and bespoke design expertise—delivering stunning rings that honour your love and your future.
