International Gold Karat Color
Gold is a precious metal that has been valued for centuries for its beauty, durability, and malleability. One of the most important characteristics of gold is its color, which can vary depending on its purity and the presence of other metals or alloys. The international gold karat system is a standardized way of measuring the purity of gold, with higher karat values indicating a higher percentage of pure gold.
Karat is a unit of measurement used to express the purity of gold. Pure gold is 24 karats, while lower karat values indicate that the gold has been alloyed with other metals, such as silver or copper. The most common karat values for gold jewelry are 18k, 14k, and 10k.
The color of gold is determined by the percentage of pure gold in the alloy. Higher karat golds have a more yellow color, while lower karat golds have a more reddish or pinkish color. The following table shows the approximate color of gold alloys of different karat values:
| Karat | Color |
|—|—|
| 24k | Pure yellow |
| 22k | Yellow with a slight reddish tinge |
| 18k | Yellow with a more noticeable reddish tinge |
| 14k | Yellow with a significant reddish tinge |
| 10k | Rose or pink |
The color of gold can also be affected by the type of metal or alloy that is used. For example, gold that is alloyed with copper will have a more reddish color, while gold that is alloyed with silver will have a more greenish color.
When choosing gold jewelry, it is important to consider the desired color as well as the purity of the gold. Higher karat golds are more expensive, but they are also more durable and have a more luxurious appearance.
