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 |

| 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 does a cluster ring mean?
A cluster ring groups several smaller diamonds together to form one design, often reading larger than the stones alone. The Trifoglio sets three round brilliant 2.00mm diamonds, 0.15ct in total, into a balanced trefoil cluster.
Are cluster diamond rings cheaper?
A cluster can offer more visible sparkle for a given budget by using several smaller stones. The Trifoglio carries 0.15ct across three F VS diamonds in solid gold or platinum, and you choose lab-grown or natural, so the price reflects your build.
Can I choose lab-grown or natural diamonds, and which metals?
Yes. The Trifoglio Cluster Ring is set with lab-grown or natural F VS diamonds in 9ct or 18ct yellow, white or rose gold, and is also available in platinum. Made to order in Byron Bay Hinterland, Australia, in 4 to 8 weeks.
