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 |

| 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 does Pyramidi mean?
Pyramidi is Italian for "pyramids." The Pyramidi Triangle Eternity Ring takes its name from the triangular pavé pattern of the diamonds, which step up in graduated formation across the band.
Can the Pyramidi stack with engagement rings?
Yes. The slim band and triangular pattern create a clean line that pairs well with solitaire and halo engagement rings.
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 Pyramidi is offered with either IGI-certified lab-grown or GIA-certified natural F VS diamonds.
How long does it take to make?
