Considerations
- Ring size can vary depending on the time of day and weather/temperature conditions.
- Ring size will also vary across both hands.
- Size may also vary according to ring design. A wider ring band may be a more snug fit compared to a narrow or slim band.
- Multiple ring resizing is not suggested as it may weaken the structure of the piece, so an accurate measurement is essential.
- Certain designs are not resizable, including most eternity rings.
- Please contact us if you have any questions about ring sizing.
Disclaimer: The size guide only provides a size reference. Ronald Abram takes no responsibility for inaccurate measurements. Please read our returns policy carefully.
