How to Care for Your Jewelry
Size Guide
Measurements on product pages are given in millimeters and inches. Use these guides to compare sizes before you order; each product page shows the sizes available for that piece.
Earring Size, Weight & Comfort
Size, next to US coins
Coins are drawn to scale with each other. Sizes on product pages are height x width in mm and inches.
Weight & comfort
We weigh one earring, not the pair. US coins weigh a fixed amount, so they make a handy reference.

Ring Size & Fit
We make whole US sizes only (no half sizes). Each product page shows the sizes available for that ring.
| US size | Inner diameter | Finger circumference |
|---|---|---|
| 4 | 14.9 mm | 46.8 mm |
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
| 13 | 22.2 mm | 69.7 mm |
How to measure
Measure the inner diameter of a ring that fits the same finger, or wrap a strip of paper around your finger and compare the circumference with the table. Measure at the end of the day when your fingers are warm, and make sure the ring can pass over your knuckle.
Wide bands (for example 8 mm) fit more snugly. If you are between sizes, choose the next size up. Tungsten rings cannot be resized, so please check your size before ordering.
If you use a printable ring sizer, print it at 100% scale. Measurements are approximate.
