What Is 18K Gold?
18K gold contains 75% pure gold and 25% alloy metals, typically a mix of copper, silver, and sometimes palladium or nickel. It is stamped as 750, indicating 75.0% gold content. 18K gold strikes an ideal balance between the rich color of high-purity gold and the durability needed for fine jewelry.
18K is the standard for fine jewelry in Europe, particularly in Italy, France, and Switzerland. It is the karat used by luxury brands including Cartier, Tiffany, and Rolex (whose gold watches are all 18K). Engagement rings, wedding bands, and high-end designer pieces are frequently crafted in 18K gold.
Compared to 14K gold, 18K has a warmer, more saturated yellow tone because of the higher gold percentage. Compared to 24K pure gold, it is significantly harder and more resistant to scratching, making it practical for everyday jewelry.
