Behind the piece

The Nova Pear & Emerald-Cut Diamond Toi et Moi Ring – Lab-Grown | 18K Gold or Platinum

Every Una ring begins with a clear point of view and a commitment to craft. Yours is no exception.

The Nova is a lab-grown toi et moi ring — two stones, set side by side, each one different. A pear-cut and an emerald-cut lab-grown diamond sit together on a single slim band, each stone angled toward the other. It is a ring that tells a story about two people, two shapes, and two ways of seeing the same thing. Made by hand to order in solid 18K gold or platinum.

Toi et moi rings have a long history as symbols of partnership and duality. The Nova combines a pear-cut lab-grown diamond (pointed, romantic, elongating) with an emerald-cut lab-grown diamond (architectural, glassy, precise) in a pairing that is deliberately contrasting and deliberately complementary. Both stones are IGI certified lab-grown diamonds.

About toi et moi rings

Toi et moi (French for "you and me") is a two-stone ring style with a rich history in fine jewellery. The Nova puts a contemporary spin on the format with contrasting cuts — the curved softness of the pear against the linear precision of the emerald. From $6,100 AUD.

Toi et moi: two stones, one ring

Toi et moi translates from French as "you and me" — a ring of two stones has meant partnership and duality for centuries. The format gained renewed attention after a series of high-profile proposals brought the style back into conversation, but The Nova is not about trend-following. A pear cut and an emerald cut are two shapes with genuinely different characters, and placing them side by side creates a dialogue between them. The pear is soft and elongating; the emerald is precise and architectural. Together, they make something more interesting than either could alone.

Lab-grown diamonds for a toi et moi ring

Getting two lab-grown diamonds to sit harmoniously in a toi et moi setting requires careful stone matching. The Nova pairs each stone from our IGI certified lab-grown inventory, with colour and clarity selected to ensure both stones read as a unified pair. Lab-grown diamonds make it far easier to achieve well-matched pairs at a sensible price point — a key advantage over mined diamonds. Browse our pear-shaped engagement rings, emerald-cut engagement rings, and oval-cut rings for other beautiful shapes.

First marriage didn't work out, but I'm pretty sure it's because it wasn't an Una Diamond!
