Purple gold, blue gold, green gold, black gold!
Mostly we think of shining yellow gold when we think of gold. This is its natural colour when 24 karat gold jewelry is created. Gold jewelry does in fact come in many colours, variants on the classic pure gold.
The most popular and most often referred to is white gold jewelry, which was first brought into vogue in the 1920's. White gold is made by adding "white" metals to gold, such as platinum, silver, zinc and nickel. White gold jewelry made with platinum can be more expensive then pure gold jewelry because platinum is currently worth more than gold.
The second most common variation on 24 karat gold jewelry is rose gold or red gold jewelry. Rose gold is created in varying hues by adding copper to gold.
In recent years, thanks to new technologies, new gold jewelry colours have evolved. Gold jewelry can now be found in colours such as black gold, green gold, purple gold and blue gold.
