Towards the center of the star the core is formed of shells of the heavier elements, the heaviest from the fusion process being iron. Heavier elements than that are then formed during the supernova. They are also created from the collision of two neutron stars, in recent years there is some research suggesting that this is actually the primary method that heavy elements are formed. Either way, that means that any gold you see is the result of the death of one or more stars.
