Gold Hallmarks in South Africa
Every piece of gold jewellery sold in South Africa must be hallmarked to confirm its purity. This mark is regulated under the South African Precious Metals Act.
Look for these stamps:
“375” or “9ct” for 9K gold
“750” or “18ct” for 18K gold
These hallmarks guarantee authenticity and ensure your jewellery meets national standards. When you buy from Moissanite By Design, you can trust that every gold piece is properly certified.
Which Should You Choose?
Choose 18K gold if you love a richer colour and want a piece with a luxurious, classic finish.
Choose 9K gold if you value strength, practicality, and affordability for everyday wear.
Both are real gold and both will last. The right choice depends on how you live and what matters most to you – richer tone or long-term wearability.

Karats for Wedding and Engagement Rings
Engagement rings and wedding bands are worn every day, so they need to be durable enough to keep their lustre. Although 24k gold is beautiful, it is also softer, making 18k or lower karats a better choice for rings that will be worn daily. Alloyed gold rings are more scratch-resistant, so choosing 14k or 18k gold for wedding and engagement rings ensures they remain beautiful through years of wear.
If you plan to wear your ring regularly, selecting an 18k or lower karat will also help maintain its pristine condition.
