SHIPPING POLICY
Last updated: September 14, 2026
NYON DIAMOND is operated by MESAC INC, a United States company. We serve approved wholesale customers, including professional piercing studios, jewelry retailers, and distributors, and maintain a showroom in New York.
This Shipping Policy explains the fulfillment and delivery arrangements for orders placed with us. Our U.S. business address and New York showroom do not mean that every order is shipped domestically within the United States. Depending on the order, delivery may involve international shipping and customs clearance.
1. SHIPPING AVAILABILITY
Shipping availability depends on the destination, product, shipment value, and available carrier services. Available destinations and delivery options are shown at checkout or confirmed in the written quotation provided before purchase.
We do not guarantee delivery to every country, region, or address. If a destination or service is unavailable, please contact support@nyondiamond.com before ordering.
2. ORDER REVIEW AND PROCESSING
Orders may include in-stock products, custom or made-to-order products, or a combination of both.
Before fulfillment, we may verify payment, wholesale account status, inventory, shipping details, and other information reasonably necessary to process the order.
For in-stock items, processing begins after the applicable payment and order details have been confirmed. Any required verification and its effect on the estimated dispatch date will be communicated to you.
If an item is unavailable or we cannot fulfill an order as agreed, we will contact you to explain the available options. We will not substitute materially different products or impose additional charges without your agreement.
If we cancel an unfulfilled order or item, we will refund the payments collected for the canceled portion, including associated charges where applicable.
3. PROCESSING, PRODUCTION, AND DELIVERY ESTIMATES
Order processing time, custom production time, and shipping transit time are separate.
The applicable processing or production estimate, estimated dispatch date or dispatch window, and estimated transit time will be provided on the product page, at checkout, or in written order terms supplied before purchase.
For custom, personalized, made-to-order, or special-order items, the production schedule depends on the agreed specifications, materials, quantities, approvals, and payment arrangements. The estimate and the conditions that start the production period will be confirmed in writing before purchase.
Please review the estimates applicable to your order. If timing is essential, contact us before placing the order so that we can confirm whether your requirements can be met.
Delivery dates are estimates unless we expressly agree to a guaranteed date in writing. This does not remove any delivery, cancellation, or refund rights available under applicable law.
4. SHIPPING METHODS AND CHARGES
Shipping services are selected according to the destination, package size and weight, shipment value, product characteristics, and service availability.
The available shipping method, service level, and shipping charges collected by us will be shown at checkout or in written terms agreed to before purchase.
Additional services, such as insurance or signature confirmation, apply only where included in the selected service or expressly agreed to. Any associated charge collected by us will be disclosed before payment.
We will not impose an additional shipping charge after purchase without your agreement.
5. COMBINED AND SPLIT SHIPMENTS
Orders containing multiple items, or both in-stock and custom items, may require combined or separate shipments.
Any planned split-shipment arrangement and related charges will be disclosed before purchase. If the arrangement needs to change afterward, we will explain the proposed change and obtain your agreement before charging any additional amount.
Where separate shipments are used, items may arrive on different dates and may have separate tracking information.
6. INTERNATIONAL SHIPPING, DUTIES, AND TAXES
Some orders may involve cross-border shipping, including orders delivered to U.S. customers.
Unless expressly included at checkout or in the written order terms, shipping charges do not include import duties, import taxes, customs clearance charges, brokerage fees, or other charges assessed by a carrier or government authority.
For business-to-business orders, the recipient is responsible for applicable import charges unless we have agreed otherwise in writing or applicable law requires a different arrangement. Relevant import-charge responsibilities will be disclosed before purchase.
Where we collect duties or taxes at checkout, those amounts will be identified in the order information. If a carrier requests payment for a charge you believe was already collected, contact us before making a duplicate payment.
Customers must provide information reasonably required for lawful customs clearance. We cannot agree to false customs descriptions or declarations.
Customs processing may affect delivery estimates. Nothing in this section excludes obligations imposed on us by applicable law.
7. SHIPPING ADDRESSES AND DELIVERY INFORMATION
Please provide a complete and accurate delivery address, recipient name, telephone number, and any necessary business delivery instructions.
To request an address correction, contact support@nyondiamond.com promptly. Changes may not be possible after processing or dispatch.
If an address error, refused delivery, or failed delivery requires a further shipping arrangement, we will contact you to explain the options and any applicable charges before arranging paid reshipment.
An unsuccessful delivery does not automatically mean that the entire order payment is forfeited. Any refund or deduction will be assessed under the agreed order terms, our Return & Refund Policy, and applicable law.
8. TRACKING AND DELIVERY ISSUES
Tracking information will be sent to the contact details associated with the order when available for the selected service.
Carrier scans may take time to update. A label-created notification does not necessarily mean that the carrier has received the shipment.
If tracking appears delayed, a shipment is reported delivered but cannot be located, or an order has not arrived within its estimated delivery window, contact support@nyondiamond.com with your order number.
We will review the available information and work with the relevant carrier where appropriate. Any replacement, refund, or other remedy will be determined under the agreed order terms and applicable law. You are not required to resolve every delivery issue with the carrier without our assistance.
9. SHIPPING DELAYS
Carrier disruptions, customs processing, severe weather, and other events may affect dispatch or delivery.
If we become aware that we cannot dispatch within the timeframe stated for your order, we will notify you, provide an updated estimate where available, and explain the available options.
Where required by law, we will obtain your consent to a delay or allow cancellation of the affected unshipped items with a prompt refund. If we cannot fulfill an item, we will cancel it and refund the applicable payment.
Circumstances outside our reasonable control do not remove rights or remedies that cannot lawfully be excluded.
10. DAMAGED, DEFECTIVE, INCORRECT, OR MISSING ITEMS
Please inspect your order when it arrives and contact support@nyondiamond.com promptly if an item is damaged, defective, incorrect, or missing.
Include your order number, the affected item and quantity, a description of the issue, and photographs of the product, packaging, and shipping label where relevant and reasonably available.
Please retain the affected goods and packaging while the issue is reviewed. Do not ship goods back until you receive the applicable return instructions.
We will investigate and arrange an appropriate remedy under the agreed order terms and applicable law. Requests for photographs or prompt notification do not remove statutory rights.
11. RETURNS AND ORDER-SPECIFIC TERMS
Returns, exchanges, and refunds are governed by our Return & Refund Policy:
https://www.nyondiamond.com/policies/refund-policy
Return destinations are assigned according to the order. Our business address and New York showroom are not automatic return destinations.
Different shipping terms may apply to a particular wholesale or custom order only where they were disclosed and agreed to before purchase, or subsequently agreed to by both parties.
A document issued after purchase does not, by itself, introduce new shipping charges or reduce previously agreed rights. Mandatory legal rights take priority over inconsistent policy or order terms.
