Comparison of Gold Purity by Country

The standards for purity and gold content around the globe vary based on the country of origin, tradition, cultural trends, economic factors, and more.

North American Countries

In the United States, Canada, and Mexico, the norm for gold is 14 karats. You will find that gold purity levels in the US typically range between 42% to 75%, with the cutoff at 10 karats and above. In Mexico and Canada, gold must be at least eight or nine karats.

European Countries

European countries generally consider the gold standard between 14 and 18 karats, but it’s lower at around eight or nine karats in some places. In Russia, karats for wedding rings will fall between nine and 14 karats, while purity wavers between 37% and 58%.

Asian Countries

In Asia, countries like India, China, and Turkey are quite stringent with gold standards, and the purer, the better. India can have high purity levels (above 90%), averaging 22 karats. The Chinese want no less than 24 karats (999.99), while Turkey’s standards range between 58% to 92% (14 to 22 karats).

Historical Trends in Gold Purity

The love affair between humans and gold goes back to ancient times, when it symbolized wealth and power. Around 1500 BC, the Egyptians developed an innovative method to verify gold purity known as “fire assaying.” The process works by firing a small sample of gold and lead in a crucible made of bone ash. The crucible absorbed the other metals, leaving behind only gold and silver.

Another historical trend in testing purity used touchstones consisting of flint slate. By scratching the gold on the touchstone, it was possible to identify the purity or content of the sample.

Fast forward to around the 1900s, and gold content and purity were slightly different than what they are now. Every goldsmith had their own method of creating gold, with varying levels of alloys. Compared to today’s gold, most antique gold has a warmer look and a copperish tone. The current demand for fine gold (gold purity above 90%) is still strong, with countries like India, Dubai, and China being some of the biggest producers and importers of 999.99 gold.

How Is Gold Purity Measured?

The karat scale is the best way to measure gold purity:

  • 8 karats: 33.3%
  • 10 karats: 41.7%
  • 12 karats: 50%
  • 14 karats: 58.3%
  • 18 karats: 75%
  • 22 karats: 91.7%
  • 24 karats: 99.9%

In addition, you can measure the content or purity of gold with some simple tests. Use a magnifying glass to inspect your gold for abnormalities, discoloration, and excessive shininess. Or, use a magnet — pure gold is not magnetic, whereas low-quality gold with base metal alloys is. Another easy test requires only a cup of water. Gold is very dense, so it will instantly sink in a cup of water. Gold alloys may float, hover, or even tilt. However, gold with heavy metal alloys may also sink.

What Factors Can Affect the Purity of Gold?

The following three properties can affect the purity of gold:

Radioactive: Uranium and thorium may occur in minimal amounts, which can be problematic for electronic applications.

Non-metallic: Oxide particles containing magnesium or chromium can affect the purity of gold, but only in very thin strips or wires.

Metallic (elemental): The most common contaminant in gold is silver. However, most 10k and 14k gold alloys contain at least 10% silver. Next are iron and copper, followed by lead and other impurities like palladium, silicon, and platinum.

How Do Laws and Regulations Impact the Purity of Gold Produced in Different Countries?
