Buying Moissanite and Lab Grown Diamond Jewellery in the Netherlands

The Netherlands sits somewhere between Germany and France on regulation: EU consumer rules apply as elsewhere, but unlike Germany there is a real hallmarking regime with an assay office behind it. For a private buyer that mostly means one additional thing to understand rather than an obstacle.

1. BTW and invoerrechten

• Invoer-BTW — import VAT on the value of the goods including shipping and any duty. Since the EU removed the low-value VAT exemption in 2021, this applies broadly regardless of value.
• Invoerrechten — customs duty above the consignment threshold, based on tariff classification and origin.
• Inklaringskosten — the carrier’s handling fee for the declaration. Not a tax, and not refundable.

An engagement ring normally sits above the duty threshold, so expect a formal clearance rather than an at-checkout arrangement. Confirm current rates with the Belastingdienst and Douane rather than relying on any retailer’s summary, this one included.

2. Hallmarking: WaarborgHolland

This is the genuine difference from Germany, and the thing Dutch buyers know but importers often do not.

The Netherlands requires precious metal articles above certain weight thresholds to carry an official hallmark — a waarborg — before being sold in the Dutch market. The system is run by designated assay offices, of which WaarborgHolland is the best known. Marks indicate the metal and its fineness, alongside a maker’s or sponsor’s mark.

What this means practically for a private buyer:

• The obligation attaches primarily to selling in the Netherlands, not to owning a piece you imported for yourself.
• An overseas maker’s 585 or 750 stamp is a fineness mark, not a Dutch waarborg. They are different things.
• Small items below the weight thresholds are exempt, so a fine chain may not require one where a substantial ring would.
• You can have a piece assayed and marked after import if you want it — relevant mainly for future resale through a Dutch professional.

Thresholds and requirements are technical and do change, so check with WaarborgHolland directly if the hallmark specifically matters to you.

3. Herroepingsrecht — and the exemption

Under Dutch implementation of the EU consumer rules, a distance purchase normally carries a 14-day herroepingsrecht — the right to withdraw without giving a reason, running from receipt.

The exemptions include goods manufactured to the consumer’s specifications or clearly personalised. A ring built to your chosen stone, metal, setting and finger size falls inside that.

Purchase	14-day withdrawal?
Stock piece, standard size	Yes
Resized before dispatch	Likely not
Built from a CAD to your spec	No
Engraved	No
Defective or not as described	Conformiteit rights apply regardless

As elsewhere in the EU, the exemption removes your right to change your mind. It does not remove your rights if the piece is defective or does not match its description — those are separate and cannot be contracted away in a consumer sale.

One Dutch-specific point worth knowing: many Dutch retailers display the Thuiswinkel Waarborg trustmark, which brings its own dispute process. An overseas seller will not have it, so your practical protection rests on the seller’s own conduct rather than a Dutch scheme — another reason to weigh how a workshop answers questions before ordering.

Delivery timing

Ask for production and transit separately. For our work: roughly seven to eight days on the bench, then 10–12 days standard transit or 6–8 expedited — about 17–20 days door to door on standard.

Add clearance, plus the depot-hold step if duties are not prepaid. Dutch domestic delivery is fast once released, so the variable part is customs rather than the final leg.

Ring sizing

The Netherlands uses the inner circumference in millimetres as its ring size — maat 54 means a 54 mm circumference. This is the most precise system in common use and it converts cleanly to nothing else.

Give the overseas workshop the Dutch number or the inner diameter in millimetres and let them convert once. Converting to a US number yourself and then having it converted back is where sizing errors come from — and a resize on a piece shipped from outside the EU means a second customs clearance.

Checklist for a Dutch buyer

1. Ask DDP or DAP before ordering.
2. If it is a surprise going to another address, resolve that first.
3. Give your ring size as the Dutch maat or the diameter in mm.
4. Confirm fineness in writing: 585, 750 or 925.
5. Decide whether a Dutch waarborg matters to you — it matters more for resale than for wearing.
6. Get production and transit quoted separately, plus clearance.
