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
What is a princess cut engagement ring?
A princess cut engagement ring features a square (or slightly rectangular) centre diamond with brilliant-cut faceting. It is the second most popular engagement ring cut after the round brilliant, prized for its modern geometry and high light return.
How does princess-cut compare to round brilliant?
Both use brilliant-cut faceting for maximum sparkle, but the princess cut is square while the round brilliant is, well, round. Princess cut tends to read more contemporary and architectural; round brilliant reads more classic and timeless.
Are the diamonds certified?
Yes. Lab-grown diamonds are IGI-certified. Natural diamonds of 0.30ct or above are GIA-certified. All diamonds are graded to F colour and VS clarity.
Can I choose between lab-grown and natural diamonds?
Yes. The Reale Princess Solitaire is offered with either IGI-certified lab-grown or GIA-certified natural F VS diamonds, at 0.50, 1.00, or 1.50ct centre weights.
How long does it take to make?
Each Reale Princess Solitaire is hand-made to order in our Byron Bay Hinterland atelier by Australian goldsmiths. Lead times typically run 4 to 6 weeks. Free shipping Australia-wide once dispatched, with Lucano's lifetime craftsmanship warranty.
