Refund policy

Last updated: July 16, 2026

We want you to be confident in every Diamooky purchase. This Refund and Return Policy applies to products purchased directly from diamooky.com.

30-Day Return Window

You may request a return within 30 calendar days after your order is delivered. To qualify, the product must be unused, uninstalled, unmodified, in its original condition and packaging, and accompanied by proof of purchase.

Starting a Return

• Return Shipping Responsibility

1. Returns Due to Seller Error or Damaged Items
If an item is returned due to an error on the seller’s part, such as receiving an incorrect item, or if the item arrives damaged, the seller will be responsible for the full cost of return shipping.

2. Returns Due to Buyer’s Remorse
If a return is requested for reasons unrelated to seller error, including ordering the wrong item, changing one’s mind, or no longer wanting the item, the buyer is responsible for the return shipping costs. Neither the original shipping fee nor the expedited shipping fee is refundable (no restocking fee will be charged). If a prepaid return shipping label is provided, the cost of the label will be deducted from the buyer’s final refund amount.

1. Email support@diamooky.com with your order number and the reason for the return.
2. Wait for a Return Merchandise Authorization (RMA) number and shipping instructions. Returns sent without a valid RMA number clearly written on the package will be refused.
3. You may use the prepaid return label supplied by us (the cost will be deducted from your refund), or you may use your own trackable shipping method.

Returns sent without prior authorization might be delayed or refused. Eligible return instructions are normally issued within one business day.

Damaged, Defective, or Incorrect Items

Inspect your order when it arrives. If an item is damaged, defective, missing parts, or different from what you ordered, contact us within 7 days of delivery and include clear photos. After verification, we will provide an appropriate replacement, refund, or other solution at no additional cost. We might not require a damaged item to be returned.

Items That Cannot Be Returned

We cannot accept returns for products that have been installed, used, altered, damaged after delivery, or returned without their original components. Gift cards and items clearly marked final sale are also non-returnable, except where applicable law requires otherwise.

Exchanges

For the fastest exchange, request a return for the original item and place a new order after the return is approved. If we shipped an incorrect or defective product, contact us before placing another order.

Refunds

After we receive and inspect an eligible return, we will notify you of the decision. Once your return is received at our warehouse, please allow 2-3 business days for inspection. After approval, refunds are issued within 3-5 business days. Your bank or card provider might require additional processing time. Unless the return is due to our error or otherwise required by applicable law, the original shipping charges and expedited shipping charges will not be refunded (no restocking fee will be charged).

Order Cancellations

To request a cancellation or address change, contact us as soon as possible. We cannot guarantee changes after an order has entered processing or shipped. A shipped order must follow the return process above.
