18k Gold
"Nickel-Free. Skin-Safe. Always."
We believe your jewelry should feel as good as it looks. That’s why every MADAJ piece is crafted from solid 18k gold, specially alloyed to be 100% hypoallergenic and nickel-free — the safest choice for sensitive skin and healing piercings.
Unlike mass-market jewelry that often contains hidden alloys like nickel (a common allergen), MADAJ uses only premium, medical-grade gold compositions. Our gold is not just skin-safe — it’s luxury-grade, durable, and made to last.
- Available in Yellow, Rose, White — and soon, Black Gold
- Zero nickel, zero irritation — even for fresh piercings
- Hallmarked for gold purity and made in our own atelier
14k vs 18k Gold:
What’s the Real Difference?
At MADAJ, we use only 18k gold — not 14k — because your skin deserves the highest purity available for everyday wear.
Some other brands use 14k gold, which contains just 58.5% pure gold — the rest is base metals like copper, zinc, and often nickel, a known allergen. While it’s commonly chosen for being harder and more cost-effective, it comes at the expense of skin compatibility and long-term value.
18k gold, by contrast, is 75% pure — richer, softer on the skin, and more resistant to tarnish and oxidation. Our proprietary alloy is nickel-free and hypoallergenic, making it the safest and most luxurious choice for piercings, especially for sensitive or healing skin.
- More gold, less risk: 18k is gentler on your skin and healing tissue
- Nickel-free by design: Always safe, even for sensitive skin
- Luxury that lasts: Richer color, better resistance, and more value over time
When you're wearing jewelry through your skin — not just on it — purity isn’t a luxury, it’s a necessity.
FAQ
18k Gold & Skin Safety
Not at all. Our 18k alloy is engineered for both durability and comfort. It’s soft enough to be gentle on healing skin, yet strong enough for daily wear — without compromising on safety or style.
While some brands choose 14k gold for its hardness and lower cost, it contains more base metals (and often nickel), which can cause skin irritation. At MADAJ, we use nickel-free 18k gold for a higher level of purity, comfort, and long-term value.
Yes. Our gold is 100% nickel-free and hypoallergenic, making it a safe and luxurious choice for sensitive skin and healing piercings.
We only use solid 18k gold — never gold-plated, vermeil, or filled. What touches your skin is the real thing, through and through.
