The substance commonly referred to as "white gold" is platinum. This precious metal is highly sought after for its rarity, durability, and resistance to tarnish. Platinum is often used in jewelry, where its lustrous finish and hypoallergenic properties make it a preferred choice for engagement rings and other fine pieces. In addition to its use in jewelry, platinum has vital applications in industrial processes, including catalytic converters in vehicles and various electronic components due to its excellent conductivity. The term "white gold" can also refer to alloys of gold and other metals like palladium or silver, but platinum is the true "white gold."
