The aforementioned materials represent distinct alloy compositions utilizing gold as a primary component, differentiated primarily by their color. One utilizes a blend incorporating white metals to achieve its pallid appearance, while the other retains the inherent hue of gold, sometimes enhanced with the addition of other metals like copper.
These materials are valuable in jewelry manufacturing due to the inherent properties of gold, such as malleability and resistance to corrosion. The choice between them often depends on aesthetic preferences, design requirements, and considerations of cost and durability. Both have been utilized for centuries, evolving with changing trends and metallurgical advancements. Their selection reflects nuanced considerations beyond mere appearance.
