Should you invest in 18k gold jewellery?

18k gold jewellery is the perfect blend of quality and durability. High amounts of pure gold give them excellent lustre. And without compromising quality, they also contain reasonable amounts of alloyed metals for increased durability.

Men and women alike have been using the shiny metals to adorn themselves for thousands of years. First, it is immensely beautiful. Secondly, it does not rust or tarnish.

Also, gold has long been recognized as a good store of value. That’s why many countries adopted the gold standard and fixed the value of their currencies in terms of a specified amount of gold

Gold retains its value over time. While inflation erodes the value of currencies, it makes gold a good hedge over inflation. 

So why not invest in gold?

When deciding to invest in gold, there are different options. 

Some of these are gold bullion (gold bars and coins), gold ETFs, and gold jewellery. 

Gold jewellery is a popular option because it comes with a unique advantage – you can wear your gold to gain social status.

The perfect gold jewellery for investment is 18k because its concentration of pure gold (75%) and alloyed metals (25%) gives it incredible shine while keeping it relatively durable.

Know that the more pure gold a piece of jewellery has, the less durable it’ll be, so it can’t withstand daily wear.

But the less pure gold it has, the less shine it’ll have.

The pros of investing in 18k gold jewellery

There are many reasons why you should consider investing in 18k gold jewellery.

  • It has a wonderful appearance
  • It is hypoallergenic

1. 18k gold jewellery has a great appearance

18k gold jewellery has a 75% concentration of pure gold, which is very high. For this reason, 18k gold jewellery have near-pure appearances.

This is unlike 14k gold jewellery that can look dull because of having only about 58% of pure gold.

2. 18k gold jewellery is hypoallergenic

Because of having fewer alloyed materials, especially nickel, 18k gold jewellery is relatively less likely to cause an allergic reaction.

Pure gold is too soft to wear, so it is usually alloyed with nickel, platinum, palladium, copper, zinc, or silver. 

Sadly, nickel which is a primary agent for bleaching gold causes allergic reactions.

The cons of investing in 18k gold jewellery

Investing in 18k gold jewellery is not without a few issues. This is because the investment is:

  • Susceptible to damage
  • Relatively expensive

1. 18k gold jewellery is susceptible to damage

Because gold is soft, the higher the concentration of pure gold in a piece of jewellery, the less durable it is. This is because a high gold concentration means a low amount of alloyed metals to “strengthen” it.

With 18k gold jewellery having 75% of soft pure gold and only 25% strengthening metals, it is very durable. 

It is less likely to tarnish or have scratches than 14k gold jewellery with 58.3% pure gold and 41.7% metals. 

2. 18k gold jewellery is relatively expensive

The more pure gold jewellery has, the more expensive it’ll be. Of the popular gold jewellery purity levels (10k, 14k, and 18k), 18k is the most expensive because it has more pure gold. 

If you invest in 18k gold jewellery, you’ll have to stump up more cash.

Know that there are a few other cons, but they generally apply to physical gold investment and not just investments in 18k gold jewellery. 

These include:

3. Lack of passive income

When you invest in 18k gold jewellery, the piece will just sit where it’s kept away. Except when you sell it, it’ll not give you any monetary reward.

This is unlike some other investments that will put passive income in your pocket regularly. 

For example, equity investment will bring dividends, investment in real estate will bring rental income, and fixed income will earn interest.

4. Gold requires additional storage and safety equipment

Having a good stock of 18k gold jewellery calls for having a safe place to store them. Gold jewellery attracts burglars. 

You may have to buy a safe and/or install security cameras.

5. Gold requires costly insurance

Having 18k gold jewellery may even be taking money out of your pocket regularly in the form of insurance. 

Having insurance ensures that you don’t lose your gold investment should your efforts at safeguarding it fail. 

If you choose to invest in gold jewellery, keep reading to choose wisely.

18k gold jewellery as an investment

Storing wealth in 18k gold jewellery is possible because they have high contents of pure gold, and gold does not lose value over time.  

Things to consider when buying 18k gold

When buying 18k gold jewellery, consider the purity level of the jewellery, the purpose of the jewellery, and the alloyed materials. 

1. The jewellery purity level

You should make sure that you buy 18k gold and not some lower karat gold. Simply look at the “hallmark” stamped on the jewellery to certify its purity.

Know that even experienced jewellers cannot tell the purity of gold by sight alone. Thankfully, the law protects consumers by requiring that any jewellery sold as gold is certified correctly, and the purity level stamped on it. 

So, to make sure that the jewellery you are buying is 18k gold, buy only hallmarked jewellery with the 18k gold certification.

2. Your lifestyle/ purpose of the jewellery

Consider whether you’ll be actively using the gold jewellery. 

The high amount of pure gold in 18k gold jewellery makes them susceptible to damage.

So, if you have an active lifestyle or plan to use the jewellery every day, you need a lower karat gold jewellery that is more durable (like a 14k). 

3. The alloyed materials

Ensure that the gold jewellery contains metals that are safe for you.

As mentioned earlier, nickel, a metal commonly used in gold jewellery, causes allergic reactions. 

So, if you are very sensitive, you should go for only Nickel-free gold jewellery.

For this, it’s important to know what metals give particular gold colours.

  • Yellow gold: This is an alloy of pure gold and metals like zinc and silver.
  • White Gold: This is an alloy of pure gold and white metals like nickel, palladium, and silver.
  • Rose Gold: This is an alloy of pure gold and a lot of copper
