Crimson gold is one variety of rose gold, but it has a higher copper content. Any form of gold other than pure gold (24k) is alloyed with other metals. Alloying is a process of combining two or more metallic elements to give greater strength and resistance to corrosion.
Basically they're gold with some other metals added either to change the color, as is the case with White and Rose Gold.
As far as price, they are all worth the same; their color does not influence their value, it is the karat that does.
Yellow gold is a gold alloy that consists of combining gold, copper and silver. This precious metal is always measured in karats. Yellow gold is the only type of gold that can be 24-karats, as white gold and rose gold require other metals in order to achieve their unique colors. A piece of yellow gold jewelry that is considered to be 24-karats means that it is 100% pure gold.
- 18K Yellow Gold: 75% fine gold, 15% copper, 10% fine silver.
- 14K Yellow Gold: 58.5% fine gold, 29% copper, 12.5% fine silver
