• This has a logarithmic effect on the price, which
is not in proportion or relative to the prices of
the smaller sizes. For example, if you paid $100 for
a 1 ‘Carat’ Madagascan Sapphire you won’t be paying
$400 for a 4 ‘Carat’ Madagascan Sapphire: You’ll probably
be paying $6-700 as the prices go up according to
the scarcity of the gemstone in large sizes.
• If you do your shopping wisely then the $6-700
that you could spend on a 4 ‘Carat’ Madagascan Sapphire could buy you nearly seven 1 ‘Carat’ Madagascan Sapphires, or two or three 2 ‘Carat’ Madagascan Sapphires.
• Another little tip is that when a gemstone hits
the ‘Carat’ marker its price increases considerably,
so if you buy a gemstone that’s a little below the
‘Carat’ mark, say 0.95 or 1.95 etc, you will be making
a nice little saving. The reason for this is that
prices increase in a steep curve, see the diagram
below for the general idea.
