What is 18ct gold and how is it stamped
18ct gold contains 75 percent pure gold and is commonly stamped “750” under the international millesimal fineness system. The UK Assay Office lists 750 as a recognised gold fineness and shows it in Convention hallmark examples.
Brief history of hallmarking and the 18ct “750” mark
- Hallmarking laws trace back to England in the 13th century, with formal systems run by the London Goldsmiths’ Company.
- Modern hallmarking uses millesimal fineness numbers. For gold the Convention recognises 375, 585, 750, 916 and 999, so “750” denotes 18ct.
- Exact “first use” of an 18ct “750” stamp varies by country and period.
- For South Africa, SABS has published hallmarking standards in the modern era, but public summaries are limited. Historical overviews reference 20th-century SABS mark sets.
