When it comes to fine jewellery, 18ct yellow gold stands out as a timeless choice, admired for its rich colour, durability, and lasting value. Here we explore the composition, benefits, and applications of this exquisite metal, helping you understand why 18ct yellow gold remains a top choice for jewellers and collectors alike.
The Composition of 18ct Yellow Gold
18ct yellow gold is an alloy that contains 75% pure gold, with the remaining 25% made up of other metals like silver and copper. This precise blend gives 18ct gold its distinctive light yellow hue and ensures it maintains the perfect balance between beauty and strength. The alloy’s composition not only enhances its durability but also makes it versatile enough for a range of jewellery-making techniques, from bench work and casting to rolling.

Best Uses for 18ct Yellow Gold
Jewellers worldwide favour 18ct yellow gold for its excellent workability and resistance to tarnish. It’s particularly well-suited for:
- Bench Work: Ideal for intricate designs and hand-crafted pieces.
- Casting: Perfect for creating detailed and complex forms.
- Rolling: Great for producing thin sheets or wires without losing integrity.
The Difference Between 18ct Solid Gold, Gold Filled, Plated, and Vermeil
It’s crucial to distinguish between 18ct solid gold and other types of gold jewellery, such as gold-filled, gold-plated, and vermeil. While these alternatives may resemble solid gold, they don’t offer the same value, durability, or longevity.
- Solid Gold Jewellery: Composed of 18 parts real gold and 6 parts other metals. It won’t tarnish or change colour over time, making it an ideal investment.
- Gold Filled Jewellery: Contains only 5% gold by weight, with a base metal like brass or copper. It’s more affordable but lacks the durability of solid gold.
- Gold Plated Jewellery: Involves a thin layer of gold on a base metal, usually less than 1% gold. It’s prone to fading and peeling, with minimal value.
- 18ct Gold Vermeil: Similar to gold plating but uses silver as the base metal. The gold layer is thin, so it wears off over time, revealing the silver underneath.
The Benefits of 18ct Solid Gold Jewellery
Choosing 18ct solid gold is an investment in quality and longevity. Unlike lower-carat gold or plated jewellery, 18ct solid gold won’t tarnish, fade, or irritate your skin, making it ideal for lifelong pieces. This premium material ensures your jewellery maintains its beauty and value over time, becoming cherished heirlooms.
