Our commitment to you

Return Policy

Every Yusei & Co. piece is crafted with exceptional care. We stand behind the quality of our stones and our work.

Because each Yusei & Co. piece we create involves rare, individually sourced stones and significant handcraft, our return policy reflects the nature of what we make. Please read the following carefully before making a purchase.

Natural & Lab-Grown Diamonds

14 days from purchase

Diamonds may be returned within 14 days of purchase. All diamond returns require verification of the micro serial number laser-inscribed on the girdle of the stone, followed by a full diamond test to confirm authenticity and condition. This verification process can take up to 3 business days. Returns will not be processed until verification is complete.

  • Stone must be in original, undamaged condition
  • Micro serial number must be intact and verifiable
  • Diamond test must confirm the stone is unaltered
  • Original certificate and packaging must be included

Exotic Opals

30 days from purchase

Opals may be returned within 30 days of purchase, provided the stone shows no damage of any kind. Opals are delicate by nature — chips, cracks, scratches, or any signs of mishandling will void the return.

  • Stone must be free of chips, cracks, and scratches
  • No signs of mishandling or improper storage
  • Original packaging and documentation must be included
  • Return must be initiated within 30 days of delivery

Ready-to-Wear Pieces

30 days from purchase

Pre-made, ready-to-wear jewelry pieces may be returned within 30 days of purchase in their original condition. Pieces must show no signs of wear, alteration, or damage. All original packaging, tags, and documentation must be included.

  • Piece must be unworn and unaltered
  • No scratches, dents, or signs of wear
  • All original packaging and tags intact
  • Return must be initiated within 30 days of delivery

Custom & Bespoke Commissions

No returns accepted

Custom and bespoke commissions are non-returnable. Each commission is designed and crafted entirely to the client's specifications — the stone selection, setting design, metal choice, and dimensions are unique to that individual order. Because no two commissions are alike and the work cannot be repurposed, all sales are final once a commission has been confirmed.

  • All commission sales are final
  • Clients are encouraged to review all design details before confirmation
  • Any concerns about craftsmanship should be raised within 7 days of delivery
