Buying jewlery from all over the world has never been easier. With just the click of a button you can now order that piece of jewelry you have always wanted.
However, it is important to remember that different places throughout the world use different units of measurement, whether it’s millimetres, inches or even a letter, so it always vital to check that you are buying the correct size for you.
Rings, especially, fall into this category. Countries in Europe, North and South America, and the UK and the nations of the Commonwealth all use different systems for measuring ring sizes so what is correct in one place might not necessarily be correct in another.
Use our ring size conversion chart below to make sure you are choosing the correct size for you. You can find out what is your ring size now with oNecklace’s own article: How To Find Your Ring Size
