Blabbing About Baubles: Gold

Kate has worn yellow, white and rose gold in her jewelry pieces. Let’s take a look at its chemical composition and what it really is.

Gold is a chemical element, found on the Periodic Table of Elements with the symbol Au and is a group 11 element. It is one of the least reactive chemical elements, and is considered to be a transition metal.  Under normal conditions, gold is firm and not liquid-like. Because of this solid state, it is often found in nuggets or grains.

Gold is considered to be the most noble of the noble metals and is the most malleable of all metals.

Have you wondered why there are different colored golds? Pure gold is slightly reddish yellow in hue. This happens with alloys, which are a combination of pure gold and another metal.  By definition, pure gold is 24k. Colored gold alloys are less than this. Denominations such as 10k, 14k, 18k, etc inform the consumer on how much pure gold is in a piece. This explains why the higher numbered karats tend to be more expensive. The increase in the amount of pure gold in the piece increases the value of the item.

White gold– an alloy of pure gold and a white metal, such as nickel, manganese or palladium.

Rose gold- an alloy of copper and pure gold. As one can imagine, the higher the content of copper, the more red/rosy the gold would appear to be. If the gold appears to be pinker than red, it contains more gold than copper.

Yellow gold- an alloy mixed with silver or copper.
