FAQ – Frequently Asked Questions About Ring Sizes

“What should I do if my size falls between two standard measurements?”

If you hesitate, consider how you will wear your ring. For daily wear, it is better to choose the larger size, which is more comfortable as the hours pass. On the other hand, for a piece worn occasionally or stacked, opt for the smaller size so it stays securely in place.

Is a ring a bit too large? There are several simple solutions:
– Silicone adjusters, practical and invisible
– A drop of clear resin on the inside of the band (ideal temporarily)
– Professional resizing for a permanent solution

Please note: not all rings can be resized easily. Be careful if you buy a model with:
– Stones all the way around the band (channel settings are delicate to rework)
– A metal like titanium or tungsten (nearly impossible to adjust)
– An interior engraving, which risks being altered during the process
