24

So, where are we now? Ah yes, 24.

Just for reference, during this shopping season, 24-carat gold is pure gold. There are no metal alloys added. As explained by http://24carat.co.uk:

"A carat as applied to gold alloys means a proportion by weight of one part in twenty-four, or 41.66 parts per 1000. The higher the carat value, the higher the proportion of gold in relation to the base metal content. Pure gold is therefore 24 carat."

So keep that in mind when you're shopping for me this year...
