Gold nuggets of various sizes have been found throughout the world. Historically, they are melted down and formed into new objects. The Welcome Stranger is the largest alluvial gold nugget found, which had a calculated refined weight of 97.14 kilograms (3,123 ozt). Three of the biggest nuggets come from the Brazilian Serra Pelada Mine. Most of the large nuggets were melted down into ingot form and so only have historical records of their size and mass.
