Description

Jewellery Facts 

Carat has two distinct meanings

Carat can refer to the quality or purity of gold –

pure gold ie  a metal that is 100% gold and nothing else but gold, is known as pure gold or 24 carat gold

So for example with a ring which is 18 carat ie 18/24s gold or put another way, 18 divided by 24 is 0.750  or 3/4

You may see jewellery marked 0.750 which is a some what modern way of writing 18ct as we say in the UK and 18k as they say in the rest of the world

The colour of pure gold is yellow. However if gold is mixed with other metals it can  become a silvery colour, known as white gold, or  pinky and is then known as rose gold

Secondly carat can refer to the weight of precious stones such as diamonds and sapphires

One carat is 1/5 of a gram – so 1/2 of a carat is 1/10 of a gram

A slightly outmoded way on expressing a diamonds weight is the point system. In this method a carat is said to be 100 points, so a 1/2 carat diamond for example would be a 50 pointer.

Platinum marks 

 In 1973 platinum was first covered by the hallmarking act,  A standard of 950 parts per thousand was introduced.

The platinum mark is an orb with a cross on the top all set within a pentagon.

First pieces  were marked  in January 1975 at the London assay office
