Will gold melt in a fire?

Gold melts at a much cooler temperature – about 2,000 degrees Fahrenheit – but that’s enough to survive most house fires. Platinum jewelry is the priciest, so it’s a good thing that the metal’s melting point is just higher than 3,200 degrees Fahrenheit. Sapphire and Ruby also possess extremely high melting points.
