Twelve tools, all free, no account
Tools
A tool answers the question a buying guide only describes. None of these try to sell you a ring, two will actively talk you out of one, and all twelve work whether or not the shop is open.
Ring size finder
Measure from a ring you already own, or a strip of paper. UK letters converted to US and European, with knuckle and band width allowances built in.
Sizing is the single biggest reason a ring order is abandoned.

Ring size converter
Convert in any direction between UK, US, European, Japanese and Swiss, with circumference and diameter in millimetres.

Ring weight estimator
How heavy a ring will be before you order it, from metal, width and size, in grams.
Weight is most of what people mean when they say a ring feels expensive.
Open the tool
Anniversary stones
The stone and metal traditionally given for every anniversary from the first to the sixtieth.
