- Definition
- The designation "18k" gold refers to an alloy containing 75% pure gold and 25% other metals, such as copper, silver, and zinc. The term "karat" here is indicative of the alloy's purity level; 24 karats equals 100% pure gold. The presence of other metals in the 18k gold alloy not only lends added strength and durability, making it suitable for daily wear items such as engagement rings and fine necklaces but also keeps the items relatively more affordable than their 24k counterparts. Moreover, the higher gold content in 18k jewelry imparts a richer, more vibrant yellow color, which can also be adjusted to different shades including white and rose gold through the variation of alloying elements. This blend of high purity with practical durability and a visually appealing color spectrum makes 18k gold a preferred choice for high-quality jewelry, offering an exquisite balance between luxury and functionality.
Yes, 18k gold is real gold. It is an alloy that consists of 75% gold and 25% other metals to enhance its durability and color.
18k gold is highly resistant to tarnish because it contains a high percentage of pure gold, which does not tarnish. However, it can slightly discolor over time due to the alloy materials mixed with the gold, but this is minimal compared to lower karat gold.
