We all know the infamous Argyle Pink Diamonds™, whose delicately flushed brilliance captured hearts and headlines alike. But, as with the finest stories, there’s more beneath the surface.

What are Argyle champagne diamonds?

While the Argyle pink diamond may have been the darling of the jewellery world, the Argyle mine’s most abundant treasure was something even more surprising: champagne diamonds.

Coined by Argyle in the 1980s to describe the stunning range of “brown diamonds” they discovered, the term “champagne” has since been widely adopted by the diamond industry. But here’s where the magic unfurls: many of these earthy beauties carry not just brown, but a soft, unmistakable pink.

A hue so present, it’s often mistaken for something else entirely.

That’s the quiet brilliance of it all. They’re not pink diamonds, but argyle champagnes with a secret blush; complex, rare, and unlike anything seen before.

While these unique stones can no longer be sourced from the mine, at Nina’s, we’re proud custodians of their extraordinary story. Through decades of partnership with Argyle, we’ve acquired some of the last and loveliest examples of these champagne treasures and given them a new home: Rosewood.

Why are Argyle champagne diamonds so rare?

Formed in the same red earth that produced the world’s most sought-after pink diamonds, Argyle champagne diamonds contain a breathtaking secondary tone, a hint of pink warmth that’s never been replicated.

They’re pink, without the pink diamond price tag.

How to style champagne diamond jewellery?

Each piece in Rosewood flaunts the rosy blush of these rare champagne diamonds, contrasting it beautifully with high-shine gold. With designs that harken back to their origins in the Kimberley region, this collection celebrates a uniquely Australian story.

The stones may be rare, but their story, rich, grounded, and gloriously Australian, is one we believe deserves to be worn every day.

Styling tips for pink champagne diamonds

Let the stone speak.

Champagne diamonds carry a warmth and depth that need little embellishment. Rosewood blends a modern edge with timeless sensibility, crafted with such care that it becomes more than jewellery; it becomes your signature.

Curate, don’t clutter.

The Rosewood collection was designed to be worn in harmony: rings, pendants, and earrings can be layered or stacked to create a look that’s considered yet effortless. Think of it as composing a visual rhythm, each piece echoing the warmth of the champagne diamond, each one adding depth without distraction.

Style with sentiment.

Whether it's worn to mark a memory, a milestone, or simply the moment you're in, your diamond should feel personal. At Nina’s, we believe jewellery is a personal statement, an extension of your story, told in precious stones and enduring design.

From our hands to yours

Rosewood is the result of uncompromising craftsmanship. Our master jewellers don’t just make jewellery; they shape modern heirlooms.Whether it’s a softly blushed champagne diamond or a finely set gold band, these designs are meant to be worn daily, lived in, and passed on.

Style them not as decoration, but as quiet declarations of who you are.

Why we fell in love with champagne

At Nina’s, every piece begins long before the design sketch. It starts with a conversation, a memory, a moment, a feeling. Rosewood is no different. This collection was born from reverence for the rare, soft sparkle of Argyle’s most quietly beautiful stones, and shaped by the hands and hearts of the people who work with them every day.

We asked a few members of our team to share what these diamonds mean to them.

“They have a colour you can’t quite describe, like pink caught in the earth, or dusk on red dust. Wearing them feels like you’re framing a moment in time. That’s how I see it.”

Nicole, Assistant Store Manager & Diamond Specialist

“There’s always been something sacred about Argyle stones. But these champagne diamonds have such a gentleness to them, a kind of grace. Rosewood had to be just as considered, as quiet and rare as the stones themselves.”

Krysta, General Manager of Marketing & Sales
