Gold is formed in quartz deposits in the earth. When erosion takes place, exposed veins of gold break off and wash into rivers and streams. The natural movement of the water tumbles the gold against sand and rocks, forming the Natural Gold Nugget. This gives each nugget its texture, shape, and character.
Natural gold is found by miners and left in its natural form, unaltered by man. Sand and rocks dull the nuggets and a slight cleaning is desired to bring out the brilliant color of gold, which averages 22kt (90%) pure. This compares with 10kt (41%) or 14kt (58.5%) gold. Natural Gold Nuggets of fine quality are unique.
The gold purity will vary from rivers and streams. Gold Nuggets can be found from 70% to as high as 95% pure depending on the mix of other minerals with the gold. This high purity accounts for the rich luster and color of natural gold. Nuggets are weighed by the troy ounce, 20 pennyweight (dwt), equaling one ounce of gold. They are sold at a premium price based on their rarity, shape, and size. Higher gold content and character have more value. This is similar to the grading of a fine quality diamond. The larger the Gold Nugget, the more rare it is. A one-ounce nugget is now considered as rare as a five-carat diamond.
