Purities of Yellow Gold
Gold purity is measured in karats (K), with 24K representing pure gold. Here's a look at the most common purities of yellow gold used in jewellery:
*
24K Gold
Purity: 99.9% pure gold.
Color: Bright, rich yellow.
*
Characteristics: Soft, malleable, and prone to scratches and dents. Typically not used for everyday jewellery due to its softness.

Color Differences and Alloy Effects
The color of yellow gold varies with its purity due to the different proportions of gold and alloying metals. Here’s how:
***
Higher Karat Gold (22K and 24K): These have a rich, deep yellow color because of the higher concentration of pure gold. They are also softer and less durable.
Medium Karat Gold (18K): This gold has a warm yellow color, slightly toned down by the presence of alloy metals. It strikes a balance between the rich color of higher karat golds and the durability needed for everyday wear.
Lower Karat Gold (14K and 10K): These have a lighter yellow color, often with a hint of whiteness due to the higher proportion of alloy metals. They are much harder and more resistant to scratches and dents.

Interesting Facts
Alloying Metals: The metals used to alloy gold, such as copper, silver, zinc, and nickel, not only affect the color but also enhance the durability of the gold.
Cultural Preferences: Different cultures have preferences for different gold purities. For example, 22K gold is highly popular in Indian and Middle Eastern jewellery, whereas 14K and 18K gold are more common in Western countries.
Hypoallergenic Properties: Higher karat golds (18K and above) are less likely to cause allergic reactions because they contain fewer alloy metals, which can sometimes cause skin irritation.
