21k jewelry vs 22k jewelry: Color

The color of gold jewelry can vary depending on its purity level, with higher purity levels often resulting in a richer, deeper yellow color. When comparing 21k and 22k gold jewelry, there can be a subtle difference in color due to their differing purity levels.

22k gold is more pure than 21k gold, with a purity level of 91.6% compared to 87.5% for 21k gold. This higher purity level can result in a slightly richer, deeper yellow color for 22k gold jewelry. 21k gold, on the other hand, may have a slightly lighter, more yellow-orange hue.

It's worth noting, however, that the color of gold can also be affected by the presence of other metals in the alloy, as well as the finishing and polishing techniques used on the jewelry. This means that there can be variation in color even among jewelry of the same karat weight.

Ultimately, the choice between 21k and 22k gold jewelry may come down to personal preference for color, as well as other factors such as durability, design options, and price.
