Find Your Perfect Fit
A guide to accurate ring sizing and diamond proportions.
1. Ring Size Conversion Chart
We use the standard Australian/UK (Alphabetical) sizing system. Use the table below to find your match based on your diameter or circumference.
| Inside Diameter (mm) | Inside Circumference (mm) | AU / UK Size | US / Canada Size |
|---|---|---|---|
| 14.1 mm | 44.2 mm | F | 3 |
| 14.9 mm | 46.8 mm | H | 4 |
| 15.7 mm | 49.3 mm | J ½ | 5 |
| 16.5 mm | 51.9 mm | L ½ | 6 |
| 17.3 mm | 54.4 mm | N ½ | 7 |
| 18.1 mm | 57.0 mm | P ½ | 8 |
| 18.9 mm | 59.5 mm | R ½ | 9 |
Includes printable ruler and physical sizing circles.
2. Stone Size: mm vs. Carat Weight
Diamond carat weight measures mass, while millimeter (mm) measures physical dimensions. Use this as a visual reference for Round Brilliant cut stones.
| Carat Weight (ct) | Round Diameter (mm) | Style Guide |
|---|---|---|
| 0.25 ct | 4.1 mm | Subtle & Minimalist |
| 0.50 ct | 5.2 mm | The Classic Choice |
| 1.00 ct | 6.5 mm | Timeless Brilliance |
| 1.50 ct | 7.4 mm | Commanding Presence |
| 2.00 ct | 8.1 mm | Luxury Statement |
Professional Measurement Tips
Temperature: Fingers shrink in the cold and swell in the heat. Measure at the end of the day when your hands are warm.
Band Width: Wider bands feel tighter on the finger. If you are choosing a wide eternity band, we recommend ordering one half-size larger.
Between Sizes: If you fall between two sizes, always opt for the larger size to ensure a comfortable fit.

Frequently asked questions
Is the Petal Ring a wedding band or anniversary ring?
At 4.00ct total diamond weight, the Petal Ring reads more as a statement anniversary eternity ring than a daily-wear wedding band. It is typically given to mark a milestone anniversary (10, 25, or 50 years) or as a major right-hand statement piece.
Natural or lab-grown?
Both options are offered. The price difference is substantial at this carat weight: lab-grown delivers the same look at roughly 50-70% of the natural price.
How is the gold sourced?
Gold is sourced exclusively from ABC Refinery, Australia's only independent refiner with simultaneous accreditation from the London Bullion Market Association (LBMA), Shanghai Gold Exchange (SGE), and CME Group COMEX.
How long does it take to make?
Each Petal Ring is hand-made to order in our Byron Bay Hinterland atelier. Lead times typically run 4 to 8 weeks. Free shipping Australia-wide once dispatched, with Lucano's lifetime craftsmanship warranty.
