How to Tell if a Necklace is Real Gold: A Guide for Buyers

Gold necklaces are true pieces of jewellery, admired by all for their beauty, luxurious feel, and long-lasting worth. Whether purchasing for oneself or as a special gift, a buyer must understand how to differentiate between real and fake gold, lest they become victims of counterfeits. With the many varieties of gold jewellery that abound today, it's sometimes hard to tell the real thing from the imitation. In this guide, we walk you step by step through practical tips and steps in identifying a real gold necklace.

Understanding Gold: The Basics

Before diving into how to identify a real gold necklace, let's start with some basics. Gold is a precious metal, prized for its rarity and resistance to tarnishing. It is measured in karats (k), with 24k gold being considered pure gold. However, pure gold is too soft for jewellery, so it's often alloyed with other metals like copper, silver, or zinc to increase durability.

The most common types of gold jewellery are:

- 24k Gold: This is pure gold, with no other metals mixed in. It has a deep, rich yellow hue but is soft and not typically used for jewellery that will be worn daily.

- 22k Gold: This is 91.7% gold, mixed with a small amount of other metals. It's still very soft but often used for high-end jewellery.

- 18k Gold: Comprising 75% gold and 25% other metals, 18k gold is a popular choice for fine jewellery. It's durable and retains much of gold's warm colour.

- 14k Gold: At 58.3% gold, this alloy is commonly used in jewellery due to its balance between strength and gold content.

- 10k Gold : The lowest gold purity of the lot at 41.7%, it's cheap but rather durable; its colour can never be the same as high karat.

Main Signs of an Authentic Gold Necklace

1. Look for Hallmarks and Stamps

One of the easiest ways to identify real gold is by checking for a hallmark or stamp on the necklace. Most reputable manufacturers mark their gold jewellery with a stamp that will indicate the karat and authenticity of the piece. For instance, you may see markings like “24k”, “18k”, “10k”, or even “750” which means 75% gold content, usually referring to 18k gold. Some other marks you might come across include:

- AU: The chemical symbol for gold.

- 585: Indicates 14k gold (58.5% gold).

- 916: Denotes 22k gold (91.6% gold).

It's important to note that not all gold jewellery will have visible stamps, especially if it's older or from a less regulated market. But if you're buying from a trusted jeweller, the stamp is a good indicator of authenticity.

2. Magnet Test

Since gold is non-magnetic, the simplest of tests is if the necklace would attract to a magnet. If the necklace sticks to the magnet, most probably it's made of some base metal or alloy containing some magnetic materials. However, note that some other metals used in gold jewellery alloys, such as iron, are also non-magnetic. So, this test should be used in combination with others for better results.

3. Check the Colour

While gold is typically associated with a rich, warm yellow colour, the colour can vary based on the karat and alloy mixture. Pure gold (24k) has a deep yellow tone, whereas lower karat gold (14k or 10k) may appear a little paler or more reddish due to the higher proportion of other metals.

Gold alloys can also be found in different colours:

There are three main types:

- Yellow Gold: The oldest kind of gold colour found in most jewellery.

- White Gold: A combination of gold and white metals, such as palladium or silver, with a silvery appearance.

- Rose Gold: A combination of gold and copper, known to appear pinkish or reddish.

If a gold necklace is shinier than it should be or if it carries some kind of different, unnatural colour, it may be fake since it is plated or coated jewellery.

4. The Acid Test

The acid test is a much more reliable method of determining whether the jewellery is made of real gold.

For this test a small drop of acid is applied on the jewellery. Depending on how the acid reacts, you can determine the purity of the gold. However, the acid test can sometimes leave marks on the gold, so it's not ideal if you don't want to risk damaging the necklace. It's best to have this test performed by a professional jeweller.

5. Weighing the Necklace

Gold is a dense metal, so solid gold jewellery will be heavier than fake gold or gold-plated pieces. If your necklace feels unusually light, it could be a sign that it's not made of solid gold. The weight can give you a rough indication of the necklace's authenticity, though it's still important to combine this with other tests to be sure.

Things to Look Out for When Buying a Gold Necklace

1. Price and Value

Real gold is a precious commodity and its price keeps changing with market demand. A necklace sold at a suspiciously low price deserves some scepticism. While discounts and sales are commonplace, dirt-cheap gold should raise a red flag. Compare prices from multiple reputable sellers to avoid overpaying or getting taken advantage of.

2. Buyer's Profile

Getting the gold jewellery from a popular jeweller is a sure and good way that can guarantee if it is originally made of real gold. Successful jewellers in business will authenticate your gold jewels by giving authentication documents and ensures to give return and exchange when it is flawed or damaged while making. Avoid any shop not popular and preferably, ask beforehand the purity, and origin status of the given necklace before acquiring.

3. Avoid Certificates Scam

Fake gold certificates often accompany fake pieces of gold. Make sure that the certificate is issued from a genuine firm, such as a renowned gemmological institute. Be cautious of online sites offering certificates with no verification process.

4. Gold Jewellery Maintenance

Real gold does not tarnish. However, as time passes by, it begins to lose shine. Regular cleaning and proper storing can maintain that shine. For example, take note of certain signs of discoloration, texture changes in your necklace-which might already indicate that they are not truly made of gold.
