Costco's jewelry return policy is unusually generous: most jewelry falls under their Risk-Free 100% Satisfaction Guarantee with no fixed time limit, and diamonds of 1.00 carat or larger have an extra documentation step. Here is how it actually works, and what to check before you rely on it.
The Policy in Practice
| Situation | What generally applies |
|---|---|
| Most jewelry | Returnable under the satisfaction guarantee, no stated deadline |
| Diamonds 1.00ct+ | Must be returned with all original IGI/GIA paperwork |
| Diamonds 1.00ct+, timing | A Costco Jewelry Credit Memo is issued and appraisal must be produced within 48 hours |
| Online orders | Returnable in warehouse or via Costco.com order history |
| Membership | Required to return; refunds go to the original payment method |
Costco updates its terms periodically. Confirm the current policy on costco.com or with your warehouse before making a purchase decision based on it.
Warranty vs Return
These get conflated constantly. The satisfaction guarantee covers you changing your mind or being dissatisfied. It is not a repair warranty. Manufacturing defects are handled separately, and normal wear, damage, and loss are not covered by either. Costco does offer jewelry repair services through its optical and jewelry counters at some locations, but availability varies.
Why the Policy Is So Good, and What It Costs You
The generous return window is real and worth having. The trade-off is selection: Costco carries a narrow, high-value assortment aimed at gifts and milestones rather than everyday rotation. For a proposal or an anniversary piece, that is a strong combination. For jewelry you intend to wear daily through showers and workouts, the more relevant question is materials rather than returns.
If You Are Buying for Everyday Wear Instead
Milestone jewelry and daily-wear jewelry are different purchases with different failure modes. Everyday pieces fail by tarnishing, turning skin green, or losing plating, none of which a return policy really solves after a year. There the thing to check is the base metal.
Where That Leaves You
That standard is what Ezra Gems is built around: hypoallergenic, waterproof, tarnish-free pieces designed for women who put jewelry on and forget about it. Shop Bestsellers for the everyday end of that split, and use Costco's guarantee for the milestone end where it genuinely shines.

Is Ezra Gems jewelry really waterproof?
Yes. Every piece is 18K gold plated over surgical stainless steel, a non reactive base that does not corrode in water, chlorine, or salt. You can shower, swim, sweat, and sleep in it.
Will it turn my skin green?
No. There is no copper or brass touching your skin, only surgical stainless steel under the gold plating, so it will not leave green marks or discoloration.
Is it hypoallergenic and nickel free?
Yes. Every piece is nickel free and free of lead and cadmium, made for sensitive skin and ears that react to ordinary gold tone jewelry.
