Chemistry Diamonds are a mineral made from carbon. They are the only gemstone made from a
single element. Diamonds contain 99.95% carbon the other 0.05% can include one
or more trace elements. These are atoms that aren’t part of a diamonds
essential chemistry, some of these atoms can influence a diamonds colour and
shape. . Nitrogen within a diamond can cause fluorescence and the yellow colour
in a diamond, Boron within a diamond a diamonds atoms will make blue diamonds.
Techniques for modifying a diamonds colour range from a simple coating to more
complex combinations of heat and pressure. Diamond colour can also be induced
by artificial irradiation and controlled heating called annealing. All diamond
colour modifications are vulnerable to heat, to be safe never use a torch or
other heat source near a coloured diamond .
Inclusions Few things in nature are absolutely perfect, this is as true with diamonds as
anything else. There are many different natural characteristics that occur in
diamonds, inclusions can become part of a diamond during formation or as a
result from its crystal structure. The effect that the different
characteristics have on a diamonds clarity grade depends on their visibility at
10 x magnification. Inclusions that are enclosed within a diamond are typically
crystal, needle, pinpoint and cloud. Enclosed inclusions as a result from the
crystal structure are generally internal graining, twinning wisp or grain
centre. Inclusions found on the surface of a diamond can include a cavity,
feathering, chip or knot.
Cleaning & Care Warm soapy water and a soft toothbrush will help maintain
the lustre of your diamond. Diamonds have a remarkable affinity for grease and
oily substances ( meaning that grease
and diamonds stick to each other ) Grease on the pavilion of your diamond will
reduce its optical performance. Do not use harsh solutions or abrasives to
clean your diamond. Visit us on a yearly basis for a FREE clean and polish
Storing Your Diamond When you are not wearing your diamond jewellery place it
in a cloth pouch or in a separate compartment to other gemstone jewellery ( i.e
sapphires and rubies are 9 on the Mohs scale and diamond is 10, a diamond is
140 times harder than sapphire and ruby ) your diamond can scratch the surface
of your gemstone jewellery.
Interesting Facts One ton of rock is mined to get less than 1/2ct of rough diamond.
Typically only 5-15% of diamonds mined are fit for gem quality and the
remainder are classed as near gem quality and industrial quality , which are
used for industry tools. Diamonds are graded using GIA’s 4’Cs which stands for Cut, Clarity, Colour
and Carat. The largest rough diamond mined was in 1905 and weighed an
impressive 3,106ct! Named the Cullian Diamond. Diamonds are said to be the
symbol of innocence and constancy.
