Important: This is an educational overview, not legal, customs, tax or investment advice. Rules can change. For a real transaction or shipment, verify the current requirements with the relevant Omani authority.

Key takeaways

  • Oman regulates precious-metal articles and uses official hallmarking as a consumer-protection mechanism.
  • MoCIIP currently highlights gold grades 916, 875 and 750; silver 999, 925 and 800; and platinum 999 and 950 in its consumer guidance.
  • The Ministry’s precious-metals laboratory tests metal content, verifies compliance and carries out legal hallmarking.
  • A hallmark supports verification, but buyers should still use licensed sellers and obtain a detailed invoice.

What is hallmarking?

Hallmarking is an official control system used to verify that a precious-metal article meets the stated fineness standard. In Oman, the Directorate General of Standards and Metrology under MoCIIP operates precious-metals testing and hallmarking functions.

Approved fineness levels highlighted by MoCIIP

  • Gold: 916 (22K), 875 (21K), 750 (18K).
  • Silver: 999, 925 and 800.
  • Platinum: 999 and 950.
Oman’s underlying precious-metals law also contains legal fineness provisions. Because rules and implementing decisions can evolve, this guide uses MoCIIP’s current public consumer guidance as the primary reference.

What the government laboratory does

MoCIIP describes services including gemstone testing, analysis of metals in gold bars, verification of jewellery against approved national standards, legal hallmarking and issuance of test certificates. The Ministry also carries out inspection campaigns in jewellery and precious-metal shops.

National hallmark symbols highlighted by MoCIIP

In its Arabic consumer guidance, MoCIIP describes the national marks used to distinguish precious metals: the khanjar symbol for gold, the dallah (traditional coffee pot) for silver, and a tower symbol for platinum.

What a buyer should check

  • Purchase from a licensed seller.
  • Check the stated fineness or karat.
  • Look for the relevant official hallmark or recognised marking.
  • Obtain a detailed invoice describing the purchased item.
  • For investment bars, also check refiner identity, serial number and assay/certificate information where applicable.

Bullion bars vs jewellery

Jewellery hallmarking rules and professional bullion-market standards are related but not identical. A retail or wholesale bullion bar may also be evaluated against refiner-specific documentation and international market standards such as LBMA Good Delivery rules.
