Why Ceramic Matters
Zirconia ceramic isn’t just pretty. It’s tough – 8.5 on the Mohs hardness scale, harder than steel, almost as durable as sapphire. It’s also biocompatible (same stuff used in dental crowns and joint implants), hypoallergenic, and lightweight enough you’ll forget you’re wearing it.
The catch? Ceramic can scuff when it rubs against softer metals. Your dumbbells and cookware might leave marks. It’s jewelry-grade material, so treat it like jewelry.
