Hallmark gold is typically categorized by its purity, which is expressed in karats (K). The most common categories include 24K (pure gold), 22K, 18K, 14K, and 10K, with 24K being the highest purity. Each karat represents a different proportion of gold to other metals, affecting both the color and durability of the gold. The hallmark indicates the metal's purity and often includes a stamp or symbol to verify its authenticity.
