As a metal, gold is classified as one of the least reactive, and it maintains its distinct characteristics without oxidizing in air or water.
History
Gold was the first metal ever known to humans due to its occurrence in natural form in streams and riverbeds. Geologically, gold is widely spread, and its occurrence and attractiveness in most parts of the world were exploited by virtually all communities who found it.
Unlike other metals that are found as ores, it is the easiest to work on because it does not require any smelting. All the communities that found gold used it for ornamental purposes, and it became very treasured over time, so much so that it was equated to and associated with deities and rulers. This made gold a symbol of power and wealth. As early as 4000 B.C., communities in the East used gold for decorative purposes. By 1500 B.C., Egypt became a wealthy nation due to the abundance of gold in its regions of Nubia.
The unique density, beauty, and scarcity of this metal led to its development as a medium of exchange since it was easily measurable.
Gold Beads
Gold beads have often been used for decorative purposes. These beads are either made from pure gold or from alloys.
Gold beads are used and valued as jewelry items such as wrist, ankle, and charm, slap and link bracelets. Necklaces and earrings are other ornamental items that can be manufactured using gold beads.
Brooches are jewelry items that are attached to garments. They may be made of beads. There are also gold beaded rosaries that are highly valued.
Gold Alloy Beads
Gold is alloyed with different metals with the purpose of attaining various desired properties such as color and durability. Metals used to alloy gold include silver, copper, zinc, nickel, platinum and iron.
Silver and copper alloys of gold are green, red or yellow while those of zinc and nickel are white in color. Green gold beads are obtained while using only silver as an alloy. Purple or violet beads are alloys o aluminum and blues ones are alloyed with indium.
Gold Plated Beads
Gold plating is achieved by depositing a thin layer of gold on the surface of another metal, usually copper and silver. However, copper and silver atoms dissolve into gold, and this process may cause tarnishing of gold beads over time depending on the thickness o the coat. To avoid tarnishing, copper and silver are plated with nickel before gold.
Gold Metalized Plastic beads
These beads are made by combining the gold metal with plastic to achieve a beautiful antique finish. They have the advantages of attaining the desired esthetic value at lower costs and being lighter in weight than pure gold beads. They are used on watches and other bead jewelry. These beads last for years without tarnishing.

The most famous of the mines called "Clogua". It is known for producing gold with a rose tint. This mine is also popular for producing the weeding rings that were worn by Queen Elizabeth, Princess Margaret, the Prince of Wales, Princess Diana and Camilla the Duchess of Cornwall.
