Diamond Purchase Policy
The diamonds featured on our website come directly from our network of trusted diamond partners, giving you access to an expansive selection beyond what is displayed in our physical store.
Because these stones are held by our partners, they are not on display in our boutique. To ensure you receive a stone that meets our exacting standards, we invite you to contact us before placing your order.
- Certificate & Vendor Review: A Derco specialist personally reviews the diamond’s grading certificate and back-end vendor data to ensure the stone meets our standards.
- Verification Guarantee: We do not process payments or fulfill any order until we have verified the diamond’s availability and confirmed it through our vendor network.
Return Policy
- All diamond remount rings, wedding sets, and altered jewelry pieces are final sales. We do provide a temporary classic solitaire setting to set the diamond in for the purpose of your proposal. The temporary setting along with the center diamond can be returned in 10 days or exchanged in 30 days.
- Within 60 days of your initial purchase, you may exchange the temporary mounting only (excluding center stone) and choose a new setting.
- Ladies wedding bands ordered in a size other than a size 5.5 are not returnable, since all other sizes would be custom made.
- All exchanges are final.
- Special orders are not returnable or exchangeable.
- If the item came with any lab grading reports, please include those with your return. Otherwise a fee of $250 will be charged to replace the report.
- Customers are eligible to make a one item return within 10 days of receipt during a six month period. A second purchase, after return, within the same six month period will not be eligible for return. Any exchanges made qualify as a return and the same policies would apply.
- Derco reserves the right to modify the upgrade and return policies at any time without notice.
