    The European Union Nickel Directive initiated in 1994 regulates the use of nickel in jewelry. Nickel is a hazardous and allergenic metal. The United States and other countries doesn't have such strict regulations therefore, check with each brand to ensure that they don't contain nickel.

    Mara Paris jewelry, our ateliers, our partners, and the production process are entirely nickel-free.

    Mara Paris jewelry is ethically handcrafted in Europe in small batches by expert artisans in our ateliers, under safe, high-quality working conditions. True jewelry craftsmanship is a skill refined over generations, where care, patience, and passion shape every step of the process. Because each piece is handmade, subtle variations may occur, making every creation uniquely yours.

    All Mara Paris jewelry is laser engraved to ensure quality and authenticity. We choose to engrave in small size, but it is easy to spot with the naked eye. To examine it in detail, you might need a loop.

    Every jewelry contains two markings:

    • Mara Paris logo
    • Official French state-recognized Mara Paris hallmark
  • Made in Paris, Istanbul, Portugal and Spain
  • GVS

    We use the GIA International Diamond Grading System. It is based on the 4 Cs – Cut, Colour, Clarity and Carat weight. This piece features round brilliant cut, natural diamonds of GVS quality. GVS diamonds offer a great balance of quality and value.

    G signifies the color quality, it is a bright white diamond within near-colorless category. G color diamonds look amazing in a pavé setting.

    VS signifies the clarity. This is an abbreviation for “very slight”, referring to inclusions, or indeed lack of them. Any inclusions in these diamonds can only be detected with an expert eye and with the use of a jeweller’s loupe.

    A GIA (Gemological Institute of America) certificate can only be provided for individual diamonds that are over 0.3 carats.

A Decade of Design, Redefined in Fine Jewelry

Natura Forma

To mark ten years of creative exploration, this first fine jewelry collection becomes a manifesto of the MARA PARIS vision. Sculpted in gold and diamonds, each piece embodies architectural clarity, emotional resonance, and a new language of contemporary luxury.

The Art of Organic Form

Rooted in the quiet intelligence of nature and the language of abstraction, each piece reflects a philosophy that embraces imperfection, transformation, and fluid evolution. Forms unfold with instinctive grace, capturing the tension between natural spontaneity and sculptural intent.

Wearable Sculpture

Designed to Move

Far beyond traditional adornment, these pieces are living forms—crafted to interact with the body, light, and motion. Asymmetrical compositions, sculptural lines, and bold negative space create a refined visual rhythm, offering a sense of elegance that is both modern and timeless.

“Walk into a crowded room, and you will be the centre of attention with Mara Paris’ have-to-look-twice Dina Ear Cuff.”
Vogue
“Mara Paris celebrates the irregularity and offbeat beauty of pearls in the new Haven collection. The new pieces are a modern rethink of traditional styles.”
