When shopping for gold jewellery, terms like gold-plated, gold-filled, and solid gold can often be confusing. Each refers to a different level of gold content and craftsmanship, and each serves a different purpose. Understanding these differences will help you make informed, lasting choices—whether for everyday wear or a treasured heirloom.
1. Solid Gold Jewellery
Definition: Solid gold refers to jewellery made entirely of gold alloy, typically in 18ct, 22ct, or 24ct purity. While 24ct is pure gold, 18ct and 22ct are blended with small amounts of other metals to enhance strength while retaining richness.
Characteristics:
- High intrinsic value – solid gold retains its worth over time.
- Durable and tarnish-resistant, ideal for everyday and lifetime wear.
- Naturally hypoallergenic, especially in higher carats (18ct+).
- Heirloom-worthy – often passed down through generations.
At PureJewels, we craft exclusively in solid gold, each piece hallmarked by the UK Assay Office, ensuring both purity and authenticity.
2. Gold-Filled Jewellery
Definition: Gold-filled jewellery is made by mechanically bonding a thick layer of gold (usually 5% of total weight) over a base metal like brass. It is not the same as solid gold, but more substantial than gold-plated.
Characteristics:
- Contains more gold than plated items, but far less than solid gold.
- Wears well for everyday use if cared for properly.
- More affordable, but does not appreciate in value like solid gold.
- Still not hypoallergenic for everyone, depending on the base metal.
Gold-filled jewellery is more durable than plating, but still not considered fine jewellery by most luxury standards.
3. Gold-Plated Jewellery
Definition: Gold-plated jewellery features a very thin layer of gold (less than 0.5 microns) applied to a base metal—often copper or brass—through electroplating.
Characteristics:
- Very affordable and widely available in fashion jewellery.
- Not durable, prone to fading, tarnishing, and rubbing off with time.
- Often contains nickel or copper, which can cause irritation for sensitive skin.
- Not suitable for daily wear or long-term use.
Gold-plated jewellery is best for short-term fashion use rather than meaningful, lasting keepsakes.
