That Green Mark on Your Skin Isn’t What You Think It Is
You’ve seen it. Took off a bracelet or a ring after a few days and found a greenish-grey shadow underneath. Assumed the jewelry was fake. Threw it in a drawer. Bought something else. Had it happen again.
Most people blame the green mark on “cheap jewelry” and move on. But the mark itself isn’t the problem — and what’s actually causing it is something the jewelry industry would prefer you never looked into.
Fact one
Most jewelry isn’t made of what it claims to be
The bracelet that says “gold-tone” on the listing? It’s a thin metallic coating — measured in microns, not millimeters — sprayed or electroplated over a base of zinc, nickel, or aluminum.
That coating is designed to look like the real thing at the point of sale. It’s not designed to last. Wear it daily — wash your hands, sweat, sleep in it — and the coating wears through.
When it does, the base metal underneath starts touching your skin directly. The green mark is your body reacting to a material you were never told was there.

Fact two
The green mark from real copper means the opposite of what you think
Solid copper — actual, 100% copper — can also leave a faint green tint on the skin. Same color. Completely different cause.
When real copper makes contact with the natural moisture and acids on your skin, it oxidizes. The result is copper salt — a harmless compound that washes off with soap and water.
With real copper, the green is a sign of authenticity. With plated jewelry, the green is a sign of decomposition — the coating dissolving and exposing whatever’s hiding underneath.
Plated jewelry
Thin coating over hidden base metal. Green mark = the piece is falling apart on your skin.
100% solid copper
Same material inside and out. Faint green = natural oxidation, proof it’s real copper.
Fact three
The word “hypoallergenic” is not regulated
There is no legal standard, no certification, and no enforcement behind the word “hypoallergenic” on a jewelry listing. Any brand can print it on any product regardless of what metals are inside.
Nickel — one of the most common contact allergens in the world — is used as a base metal in jewelry across every price point.
The only claim that means something is the material itself. Not what it’s coated with. What it’s made of. All the way through.
The difference
One material. All the way through.
Cavizio makes one product. A bracelet. 100% solid copper, hand-made in Italy. No plating. No base metal. No alloy. No coating to wear through and no mystery underneath.
What the bracelet is on the outside is exactly what it is on the inside — on day one and on day one thousand.
And because copper is one of the oldest materials humans have worn on their bodies — across civilizations, across centuries — you’re wearing something with more history than any brand name could give it.

Solid. Not plated.

What they noticed first
“I stopped wearing bracelets two years ago because everything gave me a reaction. This is the first piece I’ve worn daily in months without checking my skin every night. And it’s genuinely beautiful — people ask me where I got it.”
— Verified Cavizio customer
“My daughter bought me this after I complained about every bracelet turning my wrist green. I’ve had it on for three months straight. The quality is obvious the moment you pick it up — it has real weight to it.”
— Verified Cavizio customer
“I didn’t know the difference between real copper oxidation and cheap plating wearing off until I read about it. Now I’ll never buy plated jewelry again. This bracelet is the real thing.”

The jewelry industry has spent decades training you to blame your skin for reacting to materials it was never told about. “Sensitive skin” became the excuse. “Hypoallergenic” became the empty promise. And the drawer full of abandoned bracelets and rings became normal.
It was never your skin. It was what they put inside the jewelry and didn’t tell you about. Now you know.
