Ring Size Chart
Our rings use US sizing. Not sure which is yours? Measure in under a minute with either method below.

Option 1 — The String Test

  1. Wrap a strip of paper or string snugly around the base of your finger.
  2. Mark where it overlaps, then lay it flat and measure the length in mm.
  3. Match that number to the Circumference column below.

Option 2 — Use a Ring You Own

  1. Take a ring that already fits the right finger.
  2. Measure the inside diameter across in mm.
  3. Match it to the Inside Ø column. Between two sizes? Choose the larger.

Size Conversion Chart

US Size Inside Ø (mm) Circumference (mm)
5 15.7 49.3
5.5 16.1 50.6
6 16.5 51.9
6.5 16.9 53.1
7 17.3 54.4
7.5 17.7 55.7
8 18.1 57.0
8.5 18.5 58.3
9 19.0 59.5
9.5 19.4 60.8

11.5 21.0 65.9
12 21.4 67.2
12.5 21.8 68.5
13 22.2 69.7

Tip: measure at the end of the day when fingers are warmest, and aim for a snug fit that slides over your knuckle. Wide/comfort-fit bands can feel tighter — size up half a size.

Bold, dark, and completely original, the Black Copper Rune Core Ring is the kind of ring people ask about the moment they notice it.

A deep black exterior etched with rune-inspired markings wraps around a warm copper core, creating a contrast that's striking without being loud. The solid construction gives it real heft in your hand, the kind of weight that signals quality before anyone even looks closely at the detail.

Why you'll love it:

  • The rune carvings and copper core together create a layered look that's hard to find anywhere else at this price.
  • It won't tarnish, won't fade, and holds up to washing hands and all-day wear without losing its finish.
  • The weight and fit feel substantial, not hollow, which is exactly what you want in a ring you plan to wear often.

Once this one is gone, it's gone, so it's worth deciding soon.
