How to Shop
Choose the Right Size Collection
1. Confirm Your US Size
Use a ring sizer or measure carefully. Finger temperature, knuckle size, ring width and comfort-fit design can affect the final fit.
2. Compare the Measurements
Check inside diameter and circumference in millimetres or centimetres. These physical measurements help international customers compare sizing.
3. Open Your Size Collection
Select the relevant size card or chart button to browse rings grouped by that US ring size. Always confirm the size option on the product page.
Need to Measure First?
Use the Separate Ring Size Calculator
This page is designed for customers who already know their US ring size and want to shop by size.
When you need help converting finger circumference in centimetres or an existing ring’s inside diameter, visit the Ring Size in CM Calculator .
Important Tungsten Ring Sizing Information
Tungsten carbide rings generally cannot be resized using traditional jewellery methods. Accurate sizing is therefore especially important.
Wider bands can feel more snug than narrow bands in the same nominal size. When possible, test a ring sizer with a width similar to the ring you plan to purchase.
Check the chosen size on the individual product page before ordering, because not every style is necessarily available in every size.
Frequently Asked Questions
Shopping for Rings by Size
How do I shop for tungsten rings by US size?
Select your US ring size from the quick selector, size cards or chart. You will be taken to a collection of rings associated with that size. Confirm the required option on the individual product page before ordering.
Can customers outside the United States use this page?
Yes. Although the collections use US ring sizes, the page also shows inside diameter and circumference in millimetres and centimetres. Those physical measurements can help international customers compare their size.
What is the difference between diameter and circumference?
Inside diameter measures straight across the inner opening of a ring. Circumference measures the full distance around the inside of the ring, or around the finger where the ring will sit.
What should I do when I do not know my ring size?
Use the separate Ring Size in CM calculator to compare finger circumference or an existing ring’s inside diameter with the nearest US ring size. A physical ring sizer is recommended for final confirmation.
Do wide tungsten rings fit differently?
A wide ring can feel more snug than a narrow ring in the same nominal size because it covers more of the finger. Test a similar band width whenever possible before ordering.
Can a tungsten ring be resized?
Tungsten carbide rings generally cannot be resized using conventional jewellery techniques. Measure carefully and review the current size exchange conditions before purchasing.
Does every ring come in every listed size?
No. A size collection helps you find relevant products, but availability can vary by ring design. Confirm the exact size option and availability on the individual product page.
