Lab-grown solitaire diamond rings give you a larger, higher-quality stone for the same budget as a mined diamond solitaire. A lab-grown diamond is chemically and optically identical to a mined diamond. Certified by IGI with full 4C grades (cut, colour, clarity, carat), every stone we use is selected for cut quality first, because a well-cut diamond is what creates brilliance.

Our lab-grown solitaire rings are available in 18K yellow gold, 18K white gold, 18K rose gold, and 950 platinum. Each metal is solid — never plated — and built for a lifetime of daily wear.

Every solitaire in this collection is made to order to your finger size and chosen specifications. Delivered with an IGI grading report and a luxury presentation box. From $6,100 AUD.

The appeal of a solitaire — sometimes called a "one diamond ring" — is that everything comes down to the stone. There is no halo to distract from a smaller centre diamond, no side stones to draw the eye. A single lab-grown solitaire diamond ring stands or falls entirely on the quality of what's in the setting. That's why we select every stone for cut quality above all other criteria, and why every ring comes with an IGI certificate confirming the grade. A solitaire lab-grown diamond ring from Una Diamond can be made with any diamond shape we offer: oval, round brilliant, pear, emerald, marquise, or radiant. The same setting works across all shapes. Choose the shape that suits your partner's style, and we'll build the ring around it.
