The terms designate gold alloys with different levels of purity. “Karat” indicates the proportion of gold to other metals in the mixture, out of a total of 24 parts. A higher karat number signifies a greater percentage of gold within the alloy. For example, an alloy marked as 18 parts gold contains 75% pure gold, while an alloy marked as 14 parts gold contains approximately 58.3% pure gold.
The selection of one over the other presents a trade-off between purity and durability. Higher gold content offers a richer color and greater resistance to tarnishing but results in a softer metal that is more susceptible to scratches and bending. Conversely, lower gold content produces a more robust alloy better suited to everyday wear, at the expense of some color vibrancy and tarnish resistance. Historically, different regions and cultures have favored particular purities based on local resources and aesthetic preferences.
The following sections will delve into the specific characteristics, applications, and financial implications associated with each gold alloy. Factors such as aesthetic appearance, structural integrity, maintenance requirements, and resale value will be examined to provide a comprehensive understanding of the considerations relevant to choosing between these two options.
1. Purity
Purity, as a defining characteristic, is paramount when evaluating the differences between these two materials. It dictates not only the gold content but also significantly impacts the material’s color, density, and inherent properties. Understanding the degree of gold present is essential for assessing its suitability for various applications.
-
Gold Content Percentage
The numerical designation directly correlates to the percentage of pure gold present. This contains 75% pure gold, while that one contains approximately 58.3% pure gold. The remaining percentage comprises other metals, typically alloys of copper, silver, zinc, or nickel, added to enhance the materials hardness and alter its color. This difference in composition is fundamental to understanding their respective qualities.
-
Impact on Color and Luster
Increased gold content intensifies the yellow hue characteristic. The higher percentage presents a richer, more vibrant color. Conversely, the lower content exhibits a slightly paler, less saturated appearance. The presence of alloying metals can also subtly shift the color towards rose or white, depending on the specific metals used in the mixture.
-
Allergenic Properties
Higher levels of purity often correlate with a reduced likelihood of allergic reactions. Certain individuals are sensitive to metals like nickel or copper, which are frequently used as alloying agents. Because it contains a smaller proportion of these potentially allergenic metals, it is generally considered less likely to cause skin irritation than the alternative. However, individual sensitivities vary, and any metal alloy can potentially trigger a reaction.
-
Tarnishing Resistance
Pure gold is chemically inert and does not readily tarnish. Alloys with a greater percentage of gold exhibit superior resistance to oxidation and corrosion. While both will resist tarnishing better than alloys with even lower gold content, the alloy with higher purity will generally maintain its luster for a longer period and require less frequent cleaning.
In essence, the level of gold present is a primary differentiator, influencing a range of desirable qualities from appearance and longevity to biocompatibility.

2. Durability
The inherent softness of pure gold necessitates its alloy with other metals to enhance its durability for practical application in jewelry and other items. The difference in the proportion of gold to other metals between the two alloys directly affects their resistance to wear and tear. Higher gold content translates to reduced durability, making it more susceptible to scratches, dents, and deformation under stress. This is because the alloying metals, such as copper, silver, or zinc, impart hardness and strength to the mixture. Therefore, items crafted from the material with lower purity tend to withstand daily use more effectively than those made from the alloy with higher purity. For example, a wedding band subject to regular handling and potential impact benefits from the added strength of a lower-purity composition. Conversely, a pendant that receives less physical stress may be suitable for the higher-purity alloy.
The choice between these two, based on durability considerations, should align with the item’s intended use and the wearer’s lifestyle. A delicate necklace worn only occasionally may not require the same level of robustness as a signet ring worn daily. Furthermore, the design of the piece also plays a role. Thicker, more substantial designs inherently offer greater structural integrity, partially mitigating the reduced hardness of the higher-purity alloy. Specific protective measures, such as rhodium plating, can further enhance the scratch resistance of softer alloys, though this adds to the cost and maintenance requirements. This plating provides a hard, durable surface layer, shielding the underlying gold from abrasion.
In summary, the assessment of durability is a critical component in deciding between these two materials. The trade-off between gold purity and the alloy’s ability to withstand wear and tear requires careful consideration. Understanding the relationship between composition, design, intended use, and potential protective measures enables informed decision-making, ensuring the longevity and aesthetic appeal of the selected item.
