Gold, a precious metal, is prized for two important characteristics. First of all, gold has a lustrous beauty that is resistant to corrosion. Therefor, it is suitable for jewelry, coins and ornamental purposes. Gold never needs to be polished and will remain beautiful forever. For example, a Macedonian coin remains as untarnished today as it was 2500 years ago. Another important characteristics of gold is its usefulness to industry and science. For many years, it has been used in hundreds of industrial applications, such as photography and dentistry. The most recent use of gold is in astronaut's suits. Astronauts wear gold-plated heat shields for protection when they go outside spaceships in space. In conclusion, gold is treasured not only for its beauty but also for its utility.
