Made Locally & Ethically Sourced

Our jewelry is handcrafted by in-house artisans—each piece individually made using traditional jewelry techniques, from our hearts to yours.


We use reclaimed and recycled gold and silver, and our gemstones are fair-trade and ethically sourced.


Studio Cosette was born in the summer of 2011, in a little bachelor apartment on Yonge & Eglinton in Toronto. Though now based in Tokyo, Japan, our jewelry, with its humble beginnings, is cherished and adored by customers in every corner of the world.

Studio Cosette is a delicate and ethereal jewelry shop, inspired by clean lines and an understated elegance. Our goal is to make timeless fine jewelry that last forever.

  • The Maker & Designer

    Fai Oda is the owner & maker behind Studio Cosette. She was born and raised in sunny Bangkok, Thailand. She began jewelry self-taught, then trained with a Japanese master jeweler in Tokyo. 

    Fai has a deep connection to jewelry when she wore her late mother’s earrings and necklace on her wedding day. Jewelry for her is personal, sentimental and is a relationship from one person to another.

    When she is not forging metals, she enjoys trying out new coffee shops, visiting galleries in Tokyo, and day-dreaming about next trips with her husband.
