Choosing Your Gemstone Shape

Not sure where to start with ovals, pears, emerald cuts or something less traditional?

Our Gemstone Shape Guide walks you through every silhouette — how it looks, how it wears, and what to consider when designing your ring or jewellery.

We also have a curated selection of gemstones available in our Adelaide studio to view and try on in person.

Our Beginnings.

Carmen & Lucy Fine Jewellery is an independent South Australian studio led by gemmologist and designer Julia.

Named in honour of her grandmothers, Carmen and Lucy, the collection reflects the tradition of jewellery as a vessel for memory, a marker of milestones, and a carrier of personal meaning.

Each piece is crafted with intention — balancing beauty with structural integrity — using ethically sourced gemstones and Responsible Jewellery Council certified gold.

From bespoke designs to made-to-order favourites, we combine personalised service with exceptional craftsmanship to create modern heirlooms designed to last.
