Note: Many people ask. What is green gold? Gold is always yellow when it is 24 karat. It is usually alloyed with other metals to make the gold harder and more practical for wearing. These other metals have an effect on the color of the gold as well. In this case silver was added to the flower accents that over time oxidizes and display’s a green hue. Pink gold for example has a high percentage of copper added as an alloy and so on. The Victorians were obsessed with gold and played around with colored golds.
