PRESENTED IN A BEAUTIFUL RING BOXFREE ENGRAVING Everybody knows how precious gold is. Its qualities make it ideal for the jewellery trade,and it is also indispensible in industries as diverse as video technology,lasers,medicine & for spacecraft. Golds many uses stem from its incredible malleability & ductility,meaning it can be shaped and stretched easily; and because it is resistant to chemical changes so it doesn't tarnish as easily as some other metals. Of course,the colour as well as the physical properties means gold has been used for decoration throughout history and amongst many cultures.,History of gold,The first suggestion of gold being used for decoration was in Eastern Europe in 4000BC. In 1500BC,gold was used for trade for the first time by the Ancient Egyptians,and was first legalised as money a thousand years later in China. Between then and now,gold has been linked to many historical events and discoveries. Discoveries of new sources of gold in North America caused several infamous gold rushes during the 19th century,which hastened the colonisation of the American West. Scientific developments in France in 1927 lead to the discovery that gold can aid recovery from rheumatoid arthritis.,Yellow gold properties and usage,Gold in its pure form is too soft to be worn as jewellery,as it would not withstand the everyday stresses that jewellery is exposed to. Instead it is mixed with other metals such as e.g. copper,zinc,silver or cobalt,to make a stronger alloy. A pleasant consequence of alloying gold with other metals is that it the end result is often a different colour - so white and rose golds are now cherished in their own right.
