Hallmarking & Certification

Your guarantee of authenticity and trust.

When buying jewellery, you want assurance that what you’re paying for is genuine. Hallmarking and certification provide that peace of mind by verifying the purity of precious metals and the quality of gemstones.

What is a Hallmark?

A hallmark is a small stamp on a piece of jewellery that certifies the type and purity of the precious metal (e.g. 9ct, 14ct, 18ct gold).

• Confirms the authenticity of the material.

• Protects consumers from misrepresentation.

• Builds confidence in locally manufactured jewellery.
  

💡 Tip: Always look for a hallmark inside a ring band or on a clasp — it’s your instant quality check.

A Brief History of Hallmarking

• The practice dates back to medieval Europe, when goldsmiths marked their work to prove authenticity.

• Hallmarks became a legal requirement in many countries to protect consumers from fraud.

• In South Africa, hallmarking developed alongside the jewellery industry after the discovery of diamonds and gold in the 19th century.

• Today, hallmarking is regulated under the Precious Metals Act and overseen by the South African Diamond and Precious Metals Regulator (SADPMR).

This history underscores why hallmarking remains the foundation of trust between jeweller and consumer.

Certification for Diamonds & Gemstones

While hallmarks apply to metals, certificates verify the quality of diamonds and gemstones.

• Issued by independent labs such as GIA, EGL, IGI, and local laboratories.

• Grading reports detail the 4Cs (Cut, Colour, Clarity, Carat) of a diamond.

• Provides an impartial assessment, ensuring you get what you’ve paid for.

Why Hallmarking & Certification Matter

• Consumer Protection – Safeguards you from misrepresentation.

• Transparency – Builds trust between jeweller and customer.

• Resale Value – Hallmarked and certified items hold value better.

• Industry Integrity – Upholds standards across the South African jewellery sector.
