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.

Hallmark decoder
Read the marks struck inside an old ring: the metal, its fineness, and which assay office marked it.
Most people own a hallmarked ring and have never been told what it says.
Open the tool
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.
Forty is ruby. Thirty is pearl. Almost nobody remembers which.

Wedding date planner
Work backwards from the wedding or the proposal to the day you need to order, with slack built in.
The answer is earlier than people expect, and sizing is why.
Open the tool
Engraving preview
Type the words and see them at the real character limit for your band width and size.
Engraving is free on every ring, so you may as well use it well.
