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
What is a curb (Grumetta) chain?
A curb chain features flat, interlocking oval links that twist to lie uniformly against the skin. "Grumetta" is the Italian name for this style. Curb chains are one of the most popular gold chain types, valued for their durability and substantial feel.
9ct or 18ct — which should I choose?
9ct gold (37.5% gold) is more affordable and harder-wearing. 18ct gold (75% gold) has a richer, deeper yellow colour and feels heavier in the hand. Both are solid gold, hallmarked, and made in Italy. The 4.0mm thickness of the Grumetta gives it presence in either material.
Is the chain solid gold?
Yes. Solid gold throughout, hallmarked 375 (9ct) or 750 (18ct). Not plated or filled.
How does the Grumetta compare to the Serpente?
The Grumetta is a curb-link chain (flat interlocking ovals) with bolder visible link structure. The Serpente is a snake chain with smooth tightly-fitted segments and no visible joins. Grumetta reads more traditional and masculine; Serpente reads cleaner and more modern.
What is the warranty?
Every Lucano piece is backed by a lifetime craftsmanship warranty. Free shipping Australia-wide.
