A tribute to your past, present, and future, the cushion cut lab diamond three stone engagement ring is one of the most emotionally rich designs we offer at Diamond Lab. Paired with our sustainable values and meticulous craftsmanship, it’s become a favourite among Perth couples seeking both meaning and beauty.
The cushion cut, with its softened corners and brilliant facets, delivers exceptional sparkle with a romantic feel. When flanked by two complementary side stones—whether round, pear, or trapezoid—the centre cushion diamond becomes part of a striking trio that represents your journey together.
Our diamonds are 100% lab-grown, eco-conscious, and certified by IGI or GIA. They’re identical in brilliance and structure to mined diamonds, but far more sustainable, making them a perfect fit for modern Australian couples who want to celebrate their love without compromise.
In Perth, our three stone rings have become increasingly popular for engagements, anniversaries, and vow renewals. Every ring is made to order, and fully customisable—from your preferred diamond shapes and sizes to your choice of metal (white, yellow, or rose gold, or platinum) and setting style.
We offer virtual consultations, CAD design previews, and end-to-end support. Whether you're in Nedlands, Joondalup, or South Fremantle, our process is designed to be collaborative, personal, and seamless.
This design is particularly suited to those who want more than just a central focus—it's ideal for people who appreciate balance, storytelling, and thoughtful symbolism. With Diamond Lab, you're not just choosing a ring—you're creating a legacy.
As Australia’s #1 lab diamond jeweller, we are proud to deliver beautifully made, ethically sourced three stone rings to Perth and beyond.
