9ct and 18 ct Yellow Gold
18 carat Yellow gold is often used in engagement, wedding and eternity rings along with other high end jewellery pieces. It has a brighter and more vibrant yellow colour than 9 carat yellow gold and weighs over two thirds more than a piece of the same size.
It is often believed that 18 carat gold wears faster than 9 carat. This would seem to make sense as pure gold is very soft, however the truth is they are actually equally as hard wearing. This is why when it comes to gold it is more an issue of look and budget when deciding on your perfect piece.
