14K gold refers to a specific type of gold alloy that is used when making jewellery. 14K gold contains 75% pure gold, with the remaining 25% being made up of other metals. Because of this. As more than 50% of 18K gold jewellery is pure gold, it tends to have that iconic yellow gold look to it.

What is 18K Gold Plated Jewellery?

18K gold plated jewellery is any jewellery that features a thin layer of 18K gold. This layer is applied to a base metal.

The composition of 18K gold is 75% pure and 25% alloyed metals. Because the layer of gold is so thin, the amount of gold is incalculable.

The base layer for 18K gold-plated pieces will usually be brass, copper, nickel, stainless steel or sterling silver.

To identify if a piece of jewellery is 18K gold plated, look for the mark “18KGP”. This indicates that the piece is 18K gold-plated If your gold-plated piece doesn’t have this mark, don’t worry! It is not mandatory for gold-plated pieces to have a hallmark so some may not include it.

Pros:

  • Affordable - it’s much cheaper than a solid 18K gold jewellery piece. This makes it a great option for those who want to wear gold jewellery but are on a budget.
  • Appearance - has the same look as solid 18K gold
  • Lightweight - gold-plated pieces tend to be lighter in weight as they have less gold.


Cons:

  • Tarnishing and wear - the thin gold layer wears off over time. This can expose the base metal, leading to tarnishing. This will be dependent on the base layer metal.
  • Skin allergies - if the base metal contains any nickel, it may cause skin allergies when the gold layer fades.
  • Lower resale value - gold plated has no resale value as the amount of gold is an incalculable amount.
  • Requires more care - gold-plated jewellery needs to be cleaned and handled carefully in order to prolong its lifespan.


Differences between 18K Gold and 18K Gold Plated:

solid gold vs gold plated

Gold Percentage:

18K gold consists of 75% gold and 25% alloyed metal. 18K gold plated pieces have the same composition. However, gold-plated pieces have less overall gold.

Durability:

An 18K gold plated jewellery piece may be harder and more durable than an 18K solid gold jewellery piece. This is highly dependent on the base metal of the gold-plated piece.

18K gold is more durable in terms of dentin and scratching. It will also have longer longevity.

Allergies and skin sensitivity:

Skin allergies from jewellery are due to the presence of nickel. Nickel is present in most gold allows as well as base metal in gold-plated jewellery. The severity of these reactions depends on the composition of the 18K gold. For gold-plated pieces, the base metal will determine this.

To prevent skin allergies, choose 18K gold which has a lower percentage of nickel. For 18K gold plated pieces, choose one that features a 316L stainless steel base. Stainless steel is a hypoallergenic material that doesn't cause nickel allergies.

Price:

18K solid gold jewellery is more expensive than 18K gold plated jewellery. This is for a number of reasons. 18K solid gold pieces will have a higher content of gold. They will also require greater craftsmanship than gold-plated pieces.

Maintenance and care:

An 18K solid gold jewellery piece will be much easier to care for than an 18K gold plated jewellery piece.

For 18K solid gold jewellery pieces, all you need is to create a mixture of both warm water and mild detergent. Then just use a soft-bristled brush to clean.

For gold-plated jewellery, you will need to take more care when cleaning. Gold-plated pieces should only be cleaned with a soft, dry cloth. Avoid harsh chemical cleaners or abrasive scrubs, as this can strip the gold plating off.
