The Garden Strawberry Ring is one of my earliest designs. All of my originals are done in yellow gold (just a personal preference) but recently, I had the chance to make a strawberry in a perfectly matching rose gold.

Introduction to lost wax casting
I make all of my solid gold jewellery using the lost wax method, which involves carving a model out of wax, then having the wax model cast in precious metal.
The original Garden Strawberry ring was carved in a size 4.25:
Scaling a handcarved jewellery design
As seen in the making of the Peony Ring, moulds are a tool which can be used to reproduce a design in the exact same size:
However, moulds are not always suitable for producing rings, which come in many sizes and require designs to be scaled proportionately. To scale the Garden Strawberry to a customer's size 6, I created a new carving from scratch, with a slightly larger centre strawberry and broader leaves to fully extend to either side.
In comparison to computer-based jewellery design, which resizes a design without any changes to detail, scaling a design by hand allows me to adjust the level of detail to match the new form factor. For instance, a larger ring usually allows for clean and precise details, while a smaller ring relies on a more impressionistic approach.
The gold ring is my original design in a size 4.25, and the green wax model below it is the new carving in a size 6:

Sizing rings for lost wax casting
One of the biggest challenges of lost wax rings is accounting for the fluctuations that happen during casting and polishing. During the casting process, the ring size gets a little smaller (due to the way that metal shrinks when being cooled inside the cast). Just for reference, here's a simple diagram I drew of the casting process:

Although I carved the wax model in a size 6, the gold casting came back in a size 5.5. Bringing the ring back up to size required some gentle stretching over a steel mandrel, while accounting for the additional ring size increase that naturally happens during the polishing process. Unfortunately I don't have photos of this part, but if you're interested, you can see the full finishing process in this short video.
