A diamond is a specification. A coloured stone is a decision — about a colour, a cut, a particular piece of the earth. It is the one part of the ring that can’t be repeated.
Two sapphires of the same weight and grade are not the same sapphire. You choose the actual stone, in the hand, before anything is made.
At the same budget a coloured gemstone is usually significantly larger and more distinctive than the diamond it sits beside.
Her birth month. The colour of the water where you asked. A stone that carried down the family. Colour lets a ring say something a clear stone can't.
We only put stones into engagement rings that can take a lifetime of wear — and we'll tell you plainly when a stone you love can't.

Six to eight weeks, start to finish. Nothing is charged until you’ve seen the design and said yes to it.
Day one
Budget, her hands, what she already wears, whether she wants to know or be surprised. Half an hour, in the Burnside workshop or over the phone.
Week one
We bring out loose stones inside your budget — usually three or four to compare in daylight. You will see the differences between them immediately. Nothing is committed at this point.
Week two
Hand sketches or a CAD render, depending on the piece, with a fixed price. Changes at this stage cost nothing. We only take a deposit once you approve it.
Weeks 3–7
Cast or hand-fabricated, set and finished in Adelaide. We'll send you a photograph at the setting stage so there are no surprises.
Handover
Final fitting, an independent valuation for your insurer, and the ring in a box that won't give it away in a coat pocket.
All stone, nothing competing. Best for a stone you want people to notice.
A ring of small diamonds. Makes the centre stone read larger and protects the girdle.
Three stones — past, present, future. Also the easiest way to use a smaller centre stone well.
Metal all the way around the edge. The most protective setting we make, and the one we recommend for anything under Mohs 7.5.
Several stones read as one. Vintage in feel, and very forgiving of an unusual stone shape.
Every ring on this page is made by our sister company, Diamond Design Studios — the same bench, the same jewellers, a few metres from where the stones are kept. DDS was named Best Ring Manufacturer in Adelaide in 2017 and 2019, and took an Australian Bridal Industry Academy award in 2016.
It means nothing leaves the state to be made, and if something ever needs attention, it comes back to the people who made it.
