International Shipping and Payment Terms for Gemstone Dealers

Shipping and getting paid for loose stones internationally involves constraints most B2B sellers never encounter — worth understanding before your first cross-border sale, not after a shipment gets refused.

Not every carrier will even accept loose stones

Loose precious stones are flatly prohibited by some major couriers' standard consumer and small-business shipping services — this is a genuine, easy-to-miss constraint, not a formality. High-value gem and jewellery shipments generally need either a specialist secure-logistics carrier (Malca-Amit, Brink's, and similar firms built specifically for the trade) or a carrier's dedicated high-value/declared-value shipping program, not a standard parcel service.

Insurance and customs declaration are separate obligations

A customs declaration establishes what's crossing the border and its declared value; it does not substitute for shipping insurance, and an insurance appraisal doesn't substitute for a proper customs declaration — both need to be handled correctly and separately. Standard carrier liability without added insurance is typically capped at a low flat amount, nowhere near the value of most wholesale stone shipments — never rely on default carrier liability for anything beyond a token-value parcel.

Duty treatment varies, and loose vs set matters

Many jurisdictions treat loose diamonds as duty-free while diamonds or gemstones already set in finished jewellery carry a duty rate — this varies genuinely by country and by stone type, so confirm the specific treatment for your buyer's jurisdiction rather than assuming, and always provide a clear, itemised commercial invoice (item description, weight, declared value) to avoid customs delays.

Payment: memo is the trade's own answer to trust-at-a-distance

Memo — consigning a stone to a buyer for an agreed period (commonly 30-90 days) without upfront payment, documented in writing with insurance responsibility and return terms spelled out — is the trade's long-standing mechanism for moving higher-value goods without either party bearing the full risk of an outright pre-sale. For buyers you don't yet have that relationship with, wire transfer (or telegraphic transfer for overseas parties) remains the standard method for outright sales; agree terms and documentation in writing before goods move either way.
