Over time, jewelry can accumulate body oils and residue from skin products, which may affect the appearance of the mounting and the stones. To maintain the brightness and freshness of your jewelry, follow these simple steps:
- Take a soft-bristled toothbrush with a mild soap and gently brush both the front and back of the stones and metal.
- Rinse the jewelry thoroughly with lukewarm water to remove any soap residue.
- Avoid using ultrasonic cleaners, as they are not recommended for jewelry cleaning depending on the stones.
- Steam cleaning is an effective method, but exercise caution with emeralds or opals, as high heat can potentially damage these stones.
By regularly caring for your jewelry in this manner, you can help preserve its beauty and extend its lifespan.

Our Sapphires
At MADAJ, every sapphire we use is 100% natural and AAA quality — never lab-grown, never synthetic. Sourced responsibly from renowned origins like Sri Lanka and Madagascar and hand-selected by our expert gemologists, our sapphires are chosen for their vivid color, clarity, and ethical provenance. Whether you choose a deep royal blue or a unique custom shade, each stone comes certified alongside your jewelry piece, detailing all its characteristics.
Authentic. Rare. Brilliant.
Because your piercing deserves nothing less.
Only 18k Hypoallergenic Gold
Every MADAJ piece is crafted in solid 18k gold — always nickel-free and hypoallergenic, for maximum comfort and long-term wear.
Available in Yellow, White, and Rose Gold, 18k is the gold standard in fine jewelry — unlike 14k, which carries only 58% gold and often includes irritating base metals.
Enduring quality.
Skin-safe by nature.
Made to stay with you.

Every MADAJ piercing is made just for you — crafted to order in our own atelier, combining traditional goldsmithing with cutting-edge technology. From 3D precision to hand-finishing, our team oversees every step under one roof to ensure exceptional fit, comfort, and quality.
Nothing is mass-produced. We work from raw materials — gold, gemstones, and your specifications — to create a piece that's uniquely yours. That’s how we guarantee a perfect fit, and zero waste.
