COMPLEMENTARY MADAJ SIGNATURE BOX WITH EVERY ORDER
Every creation is carefully handcrafted and delivered in iconic Madaj packaging.

Our Emeralds
Our emeralds are 100% natural, carefully selected from trusted suppliers who work with stones originating in Colombia and Zambia — two of the most renowned sources for high-quality emeralds. Never lab-grown or treated, each stone is chosen by our expert gemologists for its deep color, natural character, and ethical provenance. The visible inclusions — known as the jardin — are part of what makes each emerald unique. Your stone is certified alongside your jewelry piece, with every detail clearly documented.
Origin matters. So does character. That’s what makes a MADAJ emerald.

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.

Made to Order, Crafted to Fit
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.
