Cobalt Halo pairs a clean, pale daytime tone with an intense cobalt-blue glow that transforms the entire ring after dark. Its broad, rounded Halo profile is finished in a smooth satin texture for a refined, understated look in daylight and a vivid presence when the lights go down.
- Whole-ring cobalt-blue glow
- Smooth satin finish
- Broad, rounded Halo profile
- Handmade by Rune Refinery
- Available in US sizes 7–14, including half sizes
Each ring is individually made, so subtle variations are part of its character.
How It's Made
Here's a quick video that shows what goes into making our rings. We hand craft each ring in house made specifically for you. We use the highest grade carbon fiber, ultra pure epoxy that has been cured and post cured for maximum strength, super bright glow and high grade materials across the board.
