・Recycled Gold・

MARIE MAS jewelry is realized using recycled gold to reduce sourcing of virgin materials.

・French Hallmark・

All of MARIE MAS jewelry pieces are hallmarked with a small Eagle Head, which is the French legislation's symbol to to certify the 18K gold quality.


Our high-quality diamonds are ethically sourced from the suppliers who follow conflict-free and socially responsible practices, and are all Kimberley process certified.


All of our gemstones are genuine mineral stones, highly valued for their beauty, longevity, and rarity. We use an array of precious and semi-precious stones, from Emeralds to Amethysts. Most of our stones are unique and have a special cut designed for our collections.


We create reusable packaging which will serve you well for years. MARIE MAS boxes are designed to keep your precious jewels safe and long-lasting, and the embroidered tote bags are made with GOTS Certified Organic cotton, both for safe-keeping. Nothing else. We hope you choose to use them for generations to come.

・Transgenerational creations・

We don't believe in ​​disposable collections. At MARIE MAS we make creations which transcend generations, adding value, meaning and soul to every piece.
