About 18ct Yellow Gold

18ct yellow gold is the preferred choice for fine jewellery worldwide, and as a plating finish it delivers the most intense, saturated yellow gold colour of any carat. The 75% gold content produces a warm, deep yellow that is immediately recognisable as premium gold — richer and more vibrant than 9ct.

Because of the higher gold content, 18ct plating is slightly softer than 9ct — but this is rarely a practical concern for plated pieces, where the base metal provides the structural hardness. The gold layer itself is what determines the colour and surface appearance.

18ct yellow gold is the standard specification for Gold Vermeil jewellery and is the most commonly requested finish for fine jewellery restoration, luxury watch plating, and premium fashion collections. When clients want the most authentic, luxurious gold appearance, 18ct is the answer.

At heavier thicknesses (Heavy, 5–10 µm), 18ct yellow gold plating provides both exceptional appearance and impressive longevity. The combination of rich colour and substantial gold content makes it the premium choice for heirloom-quality pieces.

Frequently Asked Questions

Why is 18ct more expensive than 9ct plating?

18ct contains twice the gold content of 9ct (75% vs 37.5%). For thicker deposits, the gold used per piece is significantly greater, which is reflected in the price. For thin flash deposits the difference is minimal.

Is 18ct gold plating suitable for watches?

Yes — 18ct is our most popular choice for luxury watch restoration. The rich colour is authentic to the original finish of most Swiss and Japanese dress watches, and at Heavy thickness it provides excellent longevity.

What is the difference between 18ct plating and gold-filled?

Gold-filled items have a mechanically bonded layer of gold (typically 10–50 µm) that is much thicker than electroplating. However, 18ct heavy electroplating (5–10 µm) is the practical standard for most restoration and jewellery applications, offering excellent durability at a fraction of the cost.

Can 18ct yellow gold plating be applied over white gold?

Yes. We can plate over white gold, yellow gold, silver, brass, and most base metals. The existing surface is cleaned and prepared before the new 18ct deposit is applied.
