Basic Jewellery Facts “Carat”

Just by the way the term “estate jewelry” is an Americanism for “second hand jewellery”, ie not new jewellery

What is the meaning of carat?

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 weighs one rain drop

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

What is a 100 pointer ? 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. You will find this system used in vintage books and catalogs, mostly when referring to antique diamonds – old cut, old European cut, old mine cut, old brilliant cut, swiss cut and rose cut etc

 Art Nouveau    Art Nouveau which was a more refined form of Arts and Crafts. Both fashions were at their height around the end of the 19th century. Both were a kind of reaction to the rise and dominance of mass production, The themes in Art Nouveau were long graceful curves and naturalistic subjects.
