Refund policy

This policy applies to orders placed on or after October 7, 2026. Earlier orders follow the policy in force when they were placed.

Our 30-day return window

You may return any item within 30 days of delivery for a refund of the item price to the original payment method, as long as:

The item is in unworn, original condition.
All original packaging is included (jewelry box, polishing cloth, care card).
You have a proof of purchase (order number or confirmation email).

What is refunded

A standard return, including a size you chose that does not fit, refunds the price of the item. Original shipping charges, and any import duties, taxes or customs fees paid on the order, are not refunded. If your order shipped free, the outbound shipping cost we paid to deliver it is deducted from the refund; we tell you the amount with your return instructions, before you send anything back. If the consumer law of your country gives you further rights, they apply. Any part of an order paid with store credit is refunded to your store credit.

How to start a return

Sign in to your account at mynsujewelry.com, open the order and choose Return items; or email service@mynsujewelry.com with your order number and reason for return.
We'll reply within 1 business day with return instructions, the amount of your refund and a return address.
Ship the item back to us with tracking. Return shipping cost is the customer's responsibility unless the return is due to our error (wrong item shipped, defect on arrival).
Once we receive and inspect the item, we'll process your refund within 3–5 business days.

Where returns go

Orders delivered in the United States are returned to our US receiving address. Orders delivered anywhere else are returned to our receiving address in China. The address comes with your return instructions; please do not send a return to the address printed on the parcel you received. For a return from outside the United States, any customs charges on the returned parcel are deducted from the refund.

Refunds for defects or our error

If your item arrives damaged, defective, or different from what you ordered, contact us within 3 calendar days of delivery, by email or through the contact form on our website, with a short description and photos or a video. We will cover return shipping and either replace the item or issue a full refund — your choice. For orders placed before October 25, 2026, the window is 7 days of delivery.

Craftsmanship warranty (360 days)

Every piece is covered by a 360-day craftsmanship warranty from the delivery date. If a stone comes loose, the plating fades, or the piece breaks under normal wear, email service@mynsujewelry.com with your order number and a photo. We will repair or replace the piece, and we cover return shipping once the issue is confirmed as a workmanship fault.

The warranty does not cover damage from impact, water, chlorine, perfume or other chemicals, improper storage, normal surface scratches, or lost items. Items that arrive damaged or incorrect are handled under Refunds for defects or our error above (report within 3 calendar days of delivery).

Non-returnable items

Items showing signs of wear, scratches, or damage caused by the customer.
Custom and made-to-order pieces — see Custom orders below.
Items returned after the 30-day window.

Custom orders

Custom-designed and made-to-order pieces (including CAD design services) are created specifically for you and are non-returnable and non-refundable once design or production has begun.

Design fees are non-refundable once design work starts; on a production order the fee can be reduced or waived depending on the order size.
Each production milestone proceeds only after your written approval of the design.
If a custom item arrives damaged or materially different from the approved design, contact us within 3 calendar days of delivery, with photos or a video — we will repair, replace, or refund it.

Refund timing

Refunds are issued to the original payment method. Once processed, it typically takes 5–10 business days for the funds to appear in your account, depending on your bank.

Exchanges

We do not currently offer direct exchanges. To get a different item or size, return the original under the terms above and place a new order.

Partner and wholesale orders

This policy covers retail orders placed on mynsujewelry.com. Orders placed at partner or wholesale prices follow the partner terms in the MYNSU Partner Portal, not this page.

Loose stones (moissanite melee sold by the pack at partner price) are final sale: a pack is not returned because plans changed or the stones were not used. If a pack arrives in the wrong size or grade, or short of its count, tell us within 3 calendar days of delivery with photos and we replace the pack or credit your account.
