How It Works

1. Share your starting point

Send a photo, product link or description, together with your budget and currency, ring size if known, and delivery country. Include your preferred date if you have one.

Before You Order

Timing: Standard preparation is estimated at 15 days before dispatch. Transit takes additional time. Ask us to check your preferred date before ordering.

Delivery: Complimentary standard shipping is available to destinations offered at checkout. Import duties and local taxes are additional unless checkout states otherwise.

Custom orders: Customized pieces are not eligible for non-quality returns where permitted by law. This does not affect mandatory consumer rights. Read our Shipping Policy and Refund Policy before ordering.

Tell Us What You Have in Mind

A reference photo and a budget are a useful place to begin. If you do not know your ring size or preferred specifications yet, tell us what you need help with.

Shipping & Returns

Every MISSISSI piece is made to order. This page summarizes how shipping, cancellations and returns work. The complete terms are in our Shipping Policy and Refund Policy, which take precedence if anything here differs.

Shipping

Shipping cost and destinations

Standard shipping is complimentary to destinations available at checkout. A destination may be unavailable because of carrier limitations, legal restrictions, customs requirements or other operational limits. If we cannot ship to the address provided and the order has not been dispatched, we will contact you, cancel the affected order and issue a full refund to the original payment method.

Estimated preparation time

Orders have an estimated preparation period of 15 days before dispatch. This is an estimate, not a guaranteed shipment or delivery date. Depending on the order, preparation may include order review, customization confirmation, stone selection, material sourcing, CAD or design work, sizing, engraving, personalization, manufacturing, quality control and packing.

Transit and tracking

Carrier transit time begins after dispatch and depends on the destination, carrier operations, customs clearance, weather and other circumstances outside our control. We do not publish unverified regional transit estimates. Tracking information is provided when available; carrier tracking may not update immediately after dispatch.

Preparation delays

If an order cannot be dispatched within the stated preparation period, we will notify you and provide a new estimated dispatch date, or tell you clearly if one cannot currently be provided. You may accept the delay or cancel the unshipped order for a full refund to the original payment method.

Customs, duties and taxes

Customs duties, import taxes, VAT, customs-clearance or brokerage fees and local charges are not included and are the customer’s responsibility unless checkout expressly states otherwise. International shipments may be inspected or delayed by customs. Refusing an international delivery does not automatically create a right to a full refund; duties, taxes, carrier charges, return costs and other unrecoverable expenses may be deducted where permitted by law.

Shipping address

Please provide a complete and accurate delivery address and contact information. If you find an error, email support@mississijewelry.com promptly. We cannot promise that an address can be changed after preparation or dispatch.

Cancellations

An order may be canceled for a full refund within 24 hours after payment, only if production has not started. Production is considered started when stone selection, material sourcing, CAD or design work, sizing, engraving, personalization or physical manufacturing has begun. Custom or personalized orders cannot be canceled for non-quality reasons after production has started. We do not charge a cancellation or restocking fee.

Returns

Eligible returns

Eligible non-custom and non-personalized products may be returned within 14 calendar days after delivery. To qualify, the item must be unworn, unused, unaltered, not resized, undamaged and returned with its original packaging and included documentation. Returns are subject to inspection.

How to start a return

  1. Email support@mississijewelry.com before sending anything back. Include your order number, the reason for the request, a description of the issue and photos (and video, where useful).
  2. Wait for our written return authorization. The return address and return instructions are provided after return authorization. Unauthorized returns are not automatically accepted.
  3. Ship the item using a trackable, signature-required method. Appropriate shipping insurance may be recommended for customer-paid returns, but it is not provided by MISSISSI.

Return shipping and refunds

Complimentary outbound shipping does not make ordinary return shipping free: the customer pays ordinary return shipping. There is no restocking fee. Once the item is received, inspected and approved, the refund is issued to the original payment method within 14 calendar days after approval. Your bank or card issuer may need additional time to post the credit.

Custom, resized and engraved pieces

Products made to your specifications, resized specifically for you, engraved, personalized or otherwise customized are not returnable or exchangeable for non-quality reasons, where permitted by law. A product described as made-to-order is not automatically excluded; this restriction applies only when the piece is customized for you. It does not apply to a verified defect, a wrong item or shipping damage.

Exchanges

We do not offer direct exchanges. An eligible non-custom item must be returned and inspected first; after the return is approved, you may place a new order.

Damage, Wrong Items and Quality Issues

  • Shipping damage: notify us within 48 hours after delivery and keep the product, all packaging, the shipping label and supporting photos or video.
  • Visible quality issue or wrong item: contact us within 7 calendar days after delivery with your order number, a description and photos. Please do not wear, alter or resize a wrong item.

After verification, we will arrange an appropriate repair, replacement or refund and pay reasonable authorized return-shipping costs. These notification periods do not limit any mandatory legal rights.

Lost Packages

If tracking shows a delivery problem or a shipment appears lost, email support@mississijewelry.com with your order number and we will open an investigation with the carrier. Carrier investigations do not have a fixed completion period. When the carrier confirms the package is lost, we will arrange an appropriate replacement or refund based on the order circumstances and applicable law.
