Returns Policy
Last updated: September 27, 2026
We describe every piece carefully and accurately. If something isn't right, you may return eligible items within 30 days of delivery.
What can be returned
Items must be returned in the same condition in which we sent them. We can't accept:
- Special orders and custom-made pieces.
- Items that have been worn, damaged, engraved, resized or altered by a jeweler other than us.
If a third party's opinion of a piece differs from our description, please tell us who provided it (a business card is ideal) so we can review it together. Grading involves professional judgment, and opinions can differ.
How to return a purchase
- Get a Return Merchandise Authorization (RMA) number. Call us at (646) 645-2453. Write the RMA number on the outside of the package.
- Complete the RMA form. We'll email it to you. Place the completed form inside the package.
- Pack it carefully. Include all original packaging and paperwork, every diamond certificate, and the hearts and arrows viewer if one was included (replacement fees apply if these are missing). For security, don't write our name or any description of the contents on the outside of the package.
- Insure and ship. For purchases under $25,000, send it by registered, fully insured mail via FedEx, UPS or the US Postal Service, insured for the full purchase amount. For purchases of $25,000 or more, call us first for instructions.
Return conditions
- Packages without an RMA number, received after 30 days, improperly packed or uninsured cannot be accepted.
- We are not responsible for loss or damage to return shipments.
Your refund
Refunds are the purchase price of the item(s), less shipping, handling, insurance and payment-processing fees, and are made to your original payment method within 30 days of our receiving the return. Our liability is limited to the total amount invoiced.
