This one is from the 1990s and it is actually my size. My fingers are small. Using the ISO for rings (also used in Sweden), the inside circumference of my ring finger is 15.75mm. Most shops only sell sizes from 16.25 and up. So I was thrilled when I found this on Etsy. It is on its way to me now and I will post pictures when it arrives.
International ring sizes, like shoe sizes, are tricky. From Wikipedia:
- The ISO standard for ring sizes is ISO 8653:1986, which defines standard ring sizes in terms of the inner circumference of the ring measured in millimetres.
- In the United States and Canada, ring sizes are specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch (0.8128 mm) in diameter, or roughly 1/10 inch (more precisely, 0.1005 in or 2.55 mm) in inside circumference.
- In Ireland, the United Kingdom and Australia, ring sizes are specified using an alphabetical scale, with half sizes.
- In India, Japan and China, ring sizes are specified using a numerical scale, that only has whole sizes, and does not have simple linear correlation with diameter or circumference.
- In Austria, France, Germany, Belgium and Scandinavia, ring sizes are specified using actual internal circumference in mm (the same as the ISO standard). In some countries, half sizes may be used.
- In Italy, Spain, Netherlands, and Switzerland, ring sizes are specified as the circumference minus 40mm. A 50 in Germany will be a 10 in Switzerland.
….because I love rings and buy them from everywhere, I tend to know what my ring size is in every country ha ha!
I have a plastic ring sizer (which looks like a cable tie) and also a plastic card that has circles drawn on it so that I can place my ring over the right circle and know what size it is in each country. This is very useful when I sell rings, which I do fairly often.
Anyway, this one is a pretty little thing.
