GERMANY / CLEAR DELIVERY

Serving Germany.

A direct manufacturing relationship should arrive with a clear commercial path, not a customs question at the last minute.

Germany

Elmonas ships to Germany and the EU by insured courier. Import VAT and any duties are confirmed within each quotation, so the commercial path is clear before dispatch.

Destination charges

Destination-country duties, taxes and import clearance remain the buyer’s responsibility, confirmed in writing before shipment.

Delivery timing, import VAT and any duties are confirmed for each shipment. No tax percentage is published here.

05 - HOW WE WORK

A clear make. Practical terms.

We begin with the specification and stay accountable to the stone after the finished make leaves our benches.

Payment

Built for working jewellers.

We work with established jewellers and ateliers on flexible, negotiated trade terms. First orders confirm the make; ongoing accounts move to agreed terms after credit and reference checks. We work beyond a prepaid model.

Assured make

Repair or replace.

Every stone is verified against its certificate before dispatch. In the rare case a piece needs correction - a spec mismatch, a chip, a make issue - it goes back to our benches. We repair or replace and return it.
