Diamonds in the Middle Ages






Used as medical aids and were believed to
cure illness if swallowed.
Focus on diamonds shifted from mystical
powers to their worth which increased public
awareness.
At one point rumours circulated that diamonds
were poisonous. The rumours came from mine
owners trying to prevent workers from
smuggling diamonds by swallowing them.

As diamonds are such valuable
gemstones a number of characteristics
are used to determine the price and
they are generally referred to as the
Four Cs.
1.
2.
3.
4.

The first C is Carat.
The second C is Colour.
The third C is Clarity.
The final C is Cut.

Created by: www.birthstonebrilliance.com

The first C is Carat



The mass of the diamond is
measured as carat weight.
200-milligrams is one carat and the
value of the diamond increases in
direct relation to the carat weight.

Created by: www.birthstonebrilliance.com
The second C is Colour





A colour scale grades diamonds from D
(colourless) to Z (dark yellow).
The value of a diamond is enhanced or
detracted depending on the hue and
intensity of colouration.

Created by: www.birthstonebrilliance.com
The third C is Clarity







An inclusion is a flaw inside a diamond.
It could be a tiny crack or a crystal of
foreign material that creates the
inclusion.
The clarity of a diamond is influenced in
different ways by the number, size,
colour, location orientation and visibility
of inclusions.

Created by: www.birthstonebrilliance.com
The final C is Cut.








The cut relates to the way a diamond has
been shaped and polished from a rough
stone to the final gem.
The shape of a diamond and the quality of
workmanship are both described by the
cut.
Variations of cuts, such as the emerald,
round or pear shapes are used for
different kinds of jewelry.
