About GIA

Meet Colby

GIA started with a moment.

In the lead up to her daughter Gigi Isabella’s first birthday, Colby and her mum sat down to make a necklace together — something special, something personal. It wasn’t planned. It wasn’t strategic. But the second it came together, something clicked.

This is it.

What began as a single piece quickly turned into something more. People noticed. They asked. And without overthinking it, GIA was born.

The name itself holds that story — Gigi Isabella Australia. A reflection of where it all began, and who it was for.

GIA is built on the idea that jewellery should feel like a part of you. Pieces you don’t have to think about, but always reach for. Designed to be worn daily, layered or alone, and lived in over time.

Each piece reflects Colby’s instinctive approach to design — natural textures, imperfect details, and materials that feel elevated without trying too hard.

There’s no chasing trends here. Just a focus on creating pieces that last — in quality, in style, and in feeling.

GIA is for the girl who wants to feel put together without overcomplicating it. Who understands that the smallest details can change everything.

It all started with one necklace.

And a name that means everything.
