When people hear the word gold, they often picture a shining metal that has symbolized wealth and prestige for centuries. But what many don’t know is that behind the word gold lies a whole spectrum of “purity” levels. And this gold puritydetermines not only its price but also its properties – whether we are talking about investment gold or fine gold jewelry.
What Is Gold Purity?
Gold purity describes how much pure gold is contained in an alloy. In nature, gold almost never occurs in its absolutely pure form – it is always mixed with other metals. That’s why purity is measured in karats (K):
- 24K gold (pure gold) = 99.9% pure gold – used mainly for gold bars and gold coins.
- 18K gold = 75% gold + 25% other metals – the standard for luxury jewelry.
- 14K gold = 58.5% gold – durable, ideal for everyday rings and wear.
- 9K gold = only 37.5% gold – rarely used in high-end jewelry.
The higher the karat, the softer and more malleable the gold becomes – beautiful, but also more prone to scratches. That’s why jewelers often work with 14K or 18K gold, which balances beauty with durability.
Interesting Facts You Might Not Know
-
24K gold is surprisingly soft.
Pure gold is so soft that it can even be scratched with a fingernail. This is why gold jewelry is usually alloyed with copper, silver, or palladium. -
Gold isn’t always yellow.
Alloy metals change the color of gold and give it character:
- Rose gold = gold + copper
- White gold = gold + palladium or nickel
- Green gold = lesser-known, created by mixing gold with silver (sometimes with zinc). Historically known as electrum – a natural alloy of gold and silver, used by the ancient Egyptians and Lydians to mint the very first coins. Today, green gold appears mainly in design jewelry and in the distinctive style of Black Hills Gold.

A historical curiosity:
In medieval times, 24K gold was mostly used for coins and relics, while nobility preferred 18K jewelry – it was both beautiful and durable. -
Investment perspective:
Investment gold in the form of bars and coins is always made of 24K pure gold. That’s what ensures universal value and liquidity. For jewelry, however, lower karats can be more practical since higher purity often means softness.
Why Does Purity Matter?
- For investors: purity means value security and global liquidity.
- For jewelry lovers: purity defines not just the price, but also durability and color. A 14K or 18K gold ring is more practical for daily wear than 24K gold.
- For collectors: different countries and historical periods used different purity standards (for example, Britain’s famous “royal standard” – 22K gold coins).
