In Swiss bespoke goldsmithing, fine jewelry manufacturing, and luxury watchmaking ateliers, handcrafting custom jewelry, gemstone setting, and antique restorations require flawless craftsmanship paired with strict adherence to precious metals hallmarking legislation. Because gold, platinum, and palladium represent high-value fungible assets, the Swiss jewelry trade operates under direct statutory oversight by the Central Office for Precious Metals Control within the Federal Office for Customs and Border Security (FOCBS / BAZG ). Inaccurate fineness stamps, unverified alloy blends, or deficient customer identity records when buying scrap gold under the Swiss Anti-Money Laundering Act (AMLA) result in asset confiscation and criminal prosecution. A specialized jewelry workshop platform connects precision scales, alloy catalogs, maker's marks, and job cards within an audit-proof system.

1. Statutory Framework: Swiss Precious Metals Control Act (PMCA), Maker's Marks & FOCBS Central Office

Manufacturing and trading precious metal articles in Switzerland is governed by the Precious Metals Control Act (PMCA, SR 941.31 ) and the Precious Metals Control Ordinance (PMCO, SR 941.311 ):

  • Mandatory Maker's Mark Registration (Art. 9 et seq. PMCA): Every producer of precious metal or multi-metal articles must register an official maker's mark (Verantwortlichkeitsmarke) with the Central Office at FOCBS and strike it onto every finished piece.
  • Strict Liability for Declared Fineness (Art. 7 PMCA): The holder of the registered maker's mark bears personal, strict liability for the exact fineness stamped on the article.
  • Official Assay Testing: Federal precious metal controllers perform unannounced workshop inspections and sample assays to verify compliance with legal tolerances (remedium).
Prohibition of Negative Fineness Tolerances (Art. 7 PMCO): Swiss precious metal law permits zero negative tolerance on declared fineness. A gold ring stamped "750" exhibiting an actual assayed fineness of 749.5 parts per thousand is legally counterfeit and subject to mandatory confiscation or destruction.

2. Standard Fineness Testing & Hallmarking (Gold 750, Platinum 950, Silver 925) under Swiss Law

Statutory regulations dictate permissible legal fineness standards:

  1. Standard Legal Fineness Standards under Art. 3 PMCA:
    • Gold: 916\ 0/00 (22K), 750\ 0/00 (18K), 585\ 0/00 (14K), 375\ 0/00 (9K).
    • Platinum: 950\ 0/00, 900\ 0/00, 850\ 0/00.
    • Palladium: 950\ 0/00, 500\ 0/00.
    • Silver: 999\ 0/00, 925\ 0/00 (Sterling Silver), 800\ 0/00.
    • Multi-Metal & Plated Articles: Structural base metal parts (e.g., steel springs in clasps) or electroplated layers (plaqué / doublé) must be clearly distinguished and stamped according to PMCO rules.
    • Automated Certificate Generation: Generating bespoke jewelry certificates specifying alloy composition, fineness, gemstone carat weights, cut grades, and color/clarity classifications (the 4Cs).

3. Precision Gram & Milligram Weight Tracking: Ingot Ingestion, Casting Burn-Off & Sweep Scrap Recovery

Workshop materials management requires milligram-level weight reconciliations:

  • Direct Integration with Calibrated Precision Scales: Ingesting scale readings accurate to the milligram (0.001\ g) via USB/Bluetooth to eliminate manual keyboard errors.
  • Casting Loss & Filing Scrap Reconciliation: Tracking oxidation burn-off during torch or induction casting and recovering filing scrap during sawing, shaping, and polishing (standard workshop loss ranges between 3% and 8%).
  • Refining Sweep Scrap Accounting: Maintaining separate ledger accounts for collected bench filings, polishing dust, and casting sprues, automatically valuating scrap upon dispatch to Swiss precious metal refineries.

4. Scrap Gold Procurement, AMLA Due Diligence Auditing & Precious Metals VAT

Commercial procurement of old jewelry, scrap gold, and melt material is subject to strict compliance rules:

  • AMLA Due Diligence (SR 955.0) & FOCBS Melter Licenses: Verifying and logging seller identification (official passport / ID card) and obtaining signed declarations of lawful ownership to prevent stolen property transactions.
  • Audit-Proof Melt Ledger: Tamper-proof logging of transaction dates, vendor credentials, tested fineness, gross/net weights, and payment methods.
  • Swiss VAT Structuring on Precious Metals (FTA / ESTV): Tax exemption for qualifying investment-grade gold coins and bars under Art. 44 VATO vs. the standard 8.1% VAT rate on bespoke jewelry fabrication and repair labor.
