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.
