As a precious metals expert with extensive knowledge in the field of jewelry and investments, I can provide you with a detailed comparison between white gold and yellow gold.
White gold is an alloy made primarily of gold, which is mixed with other metals such as nickel, manganese, or palladium to give it a white appearance. The purity of white gold can vary, but it is often 18 karat (75% gold) or 14 karat (58.5% gold). The value of white gold is determined by the gold content and the current market price of gold, as well as the added cost of the alloying metals and the manufacturing process.
Yellow gold, on the other hand, is also an alloy, but it has a higher gold content, typically 24 karats (99.9% gold), although it can be mixed with a small amount of other metals to improve its hardness and durability. The value of yellow gold is also based on the gold content and the market price of gold.
