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 an emerald cut engagement ring?
An emerald cut engagement ring features a rectangular centre diamond with stepped, parallel facets that produce a clean, hall-of-mirrors brilliance rather than the fiery sparkle of a brilliant cut. The shape is architectural, calm, and reads larger than its carat weight thanks to its elongated outline.
Is the emerald cut a good choice for engagement?
Yes. The emerald cut has been used in engagement rings for a century and is particularly popular among buyers drawn to vintage and Art Deco aesthetics. It is one of the original "fancy cuts" defined by GIA, alongside the round brilliant and the princess.
How does the emerald cut compare to the radiant cut?
Both are rectangular, but emerald-cut has long stepped facets (clarity-led), while radiant-cut has brilliant-cut faceting (sparkle-led). See the Imperia Radiant Solitaire for the radiant version of this design.
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.
How long does it take to make?
Each Imperia Emerald 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.
