Ring Size Information & ChartUpdated a month ago
All LOUISE JEAN engagement rings and wedding bands are handcrafted to order and can be made to any size requirements, with the exception of our ready-to-wear pieces.
Our rings are made to Australian ring sizes, based on an alphabetical scale from F - Z. These letters correlate with the internal diameter of the band, measured in millimetres. The difference from one ring size to the next is a matter of 0.2mm. The difference between a ring that fits and one that doesn’t could be just 0.4mm.
