24K gold is considered “pure gold” because it contains 99.9% gold content with virtually no other metals mixed in. In the carat system, which measures purity out of 24 parts, 24 carats means 24 out of 24 parts are gold—hence, it is the highest possible level of purity in gold.

Why 24K Gold is Called “Pure”

Purity by Definition

• 24K (or 24ct) gold is 99.9% pure (also expressed as 999 fineness).

• It contains no significant alloyed metals, which means the gold is in its natural, most refined state.

Rich Colour and Softness

• 24K gold has a deep, rich yellow hue—the hallmark of high-purity gold.

• It is so soft and malleable, it’s not generally used for jewellery, as it can bend or scratch easily. Instead, it is ideal for investment in the form of coins and bars.

Standard for Investment

Because of its uncompromised purity, 24K gold is the preferred choice for gold bullion (bars and coins) used by:

• Central banks

• Investors

• Jewellery traders

In the UK, Royal Mint Britannia coins, made of 24K gold, are VAT-free and exempt from Capital Gains Tax, making them a highly tax-efficient investment.

How It’s Certified

24K gold is often marked as:

• “999” (indicating 999 parts per 1,000 are gold)

• Hallmarked for assurance by assay offices
