An alloy of gold, copper, and sometimes silver, this particular material composition is frequently utilized in the creation of adornments. The presence of copper lends a reddish hue, the intensity of which depends on the proportions within the mix. For example, a piece marked as 14 karats signifies that it comprises 14 parts pure gold and 10 parts other metals, contributing to both its color and structural integrity.
The increasing preference for this material in jewelry stems from its warm aesthetic, complementary to various skin tones, and perceived romantic connotation. Historically, the addition of copper to gold to create colored alloys dates back centuries, but its resurgence in modern fashion highlights its timeless appeal. Furthermore, the inclusion of alloyed metals enhances the durability of the relatively soft pure gold, making it suitable for daily wear.
