How insured shipping of loose stones works

A fine loose stone crosses borders in a parcel the size of a paperback, and it does so safely thousands of times a week. The machinery behind that, specialist couriers, cargo insurance and customs brokerage, is mature and deliberately dull. Understanding it is mostly a matter of knowing who carries which risk at which moment.

Who actually carries stones

At the top of the market, specialist valuables couriers, the secure-logistics houses that serve banks, auction rooms and the diamond trade, move goods door to door under their own security chain, with insurance arranged as part of the service. For the broad middle of the trade, the familiar express carriers do the physical work. The distinction that matters is not the van but the cover: the standard declared-value protection sold by a general courier typically caps or excludes loose gemstones altogether, whatever the label on the waybill suggests.

The gap is closed by shipper's insurance: either the dealer's own block policy, the all-risks cover a stone dealer carries on goods in trust and in transit, or per-shipment cargo cover placed with specialist underwriters. When a dealer says the shipment is fully insured, the useful follow-up is under whose policy, and to what value.

What it costs

Per-shipment cover on stones is normally quoted as a small percentage of declared value, commonly a fraction of one percent, rising with route and circumstance. The declared value is the invoice value. Under-declaring to soften duties voids the insurance and compromises the customs entry at both ends, which is why a request to mark down the paperwork is a request for you to carry the risk. Decline it, and be wary of a dealer who volunteers it.

The paperwork

• A commercial invoice stating the goods, their value and the tariff heading for loose coloured stones.
• A copy of the lab report where one exists; it identifies the goods for insurer and customs alike.
• Export permits where the origin country requires them.
• At import, for larger values, a customs broker who files the entry and collects what is due.

Duties and taxes

Under the terms most trade shipments use, the buyer is the importer: any import duty and the local sales tax or VAT fall due on arrival, on top of the wire already sent. Many markets admit loose coloured stones at low or zero duty, but consumption taxes commonly apply in full. The rates are knowable in advance. Ask the dealer or the broker to state them before despatch, and treat the landed cost, not the invoice, as the price of the stone.

Packaging and discretion

Stones travel in parcel papers or cases inside tamper-evident bags, inside plain outer boxes that say nothing about their contents. No gem wording on the outside, a signature required at delivery. Some policies specify the packing method; the shipping dealer handles this, and the absence of drama in the packaging is part of the security.

When risk passes, and what to do on arrival

Cover normally runs door to door and ends at the delivery signature. From that moment the stone is yours to protect, so the arrival routine matters. Inspect at once. If the outer packaging is damaged, photograph it before opening. Report any loss or damage within the policy's claim window, which can be as short as a day or two. For approval shipments, agree in writing who insures the stone during the approval period and on the return leg; the return is where cover most often silently lapses.

Before the stone ships, ask

• Whose insurance covers this shipment, and to what value?
• Is the full invoice value declared?
• Who is the importer of record, and what taxes will arrive with the parcel?
• What is the claims window on delivery?

Four questions, four written answers, and the riskiest-looking part of the purchase becomes the most routine. Verified dealers on GemsVerified are asked about their shipping and insurance practice at admission; the policy that covers your parcel is still worth naming before it moves.
