The Real Copper Test

Most Bracelets Can't.

The Science

Why the Ice Melt Test Matters

Copper's thermal conductivity isn't just a party trick. It's the same property that allows real copper to interact with your body's natural electrical system — conducting warmth, energy, and trace minerals through your skin.

401 W/mK
Pure copper's thermal conductivity — transfers heat faster than almost any material on Earth. That's why it melts ice on contact.
99.9%
Purity of every Cavizio cuff. No plating. No alloy blends. Just solid copper that passes the ice test, every time.
2mg /day
Recommended daily copper intake for adults. Wearing copper on skin allows trace absorption — a practice used for over 5,000 years.
"Copper has been shown to have anti-inflammatory and antioxidant properties. When worn against the skin, trace amounts can be absorbed transdermally — a principle that ancient civilizations understood intuitively."

I was skeptical — I've tried three "copper" bracelets from Amazon and none of them did anything. My daughter showed me the ice test trick and we tested my old ones. Nothing. Then we tested this one and it went straight through. Within two weeks, the stiffness in my wrist was noticeably better. I wear it 24/7 now.

The quality is incredible. It doesn't turn my skin green like the cheap ones. My husband saw me wearing it and asked for one too — that's why I love the BOGO deal. We both wear them every day. My hands feel so much better in the mornings.

I'm a nurse and I'm on my feet all day. My wrists ache from charting and lifting patients. A coworker recommended Cavizio and I've been wearing mine for 6 weeks now. The difference is real. I even got compliments on how elegant it looks — people can't believe it's copper.

Frequently Asked Questions

Place any copper item on an ice cube. Pure copper has a thermal conductivity of 401 W/mK — meaning it transfers heat incredibly fast. A real copper bracelet will melt through ice in seconds. Copper-plated or alloy bracelets won't, because the base metal underneath doesn't conduct heat the same way. It's the simplest proof of purity.
No. Cavizio cuffs are specially treated to prevent oxidation while still allowing trace copper absorption. Unlike cheap copper bracelets that use reactive alloys, our 100% pure copper with protective finishing means no green marks on your skin — guaranteed.
Absolutely. Every Cavizio cuff is fully waterproof. Shower, swim, wash dishes — it stays on. Most of our customers never take it off, and the cuff maintains its finish for years.
