Brilliance - This is the sparkle
that is seen in a gemstone when it is held up to the light.
It is caused by the reflection of “white”light back from
a gemstone, both from its surface and from within. The
more “white” light reflected back, the greater the brilliance.
The brilliance of a gemstone is influenced by its cut,
its proportions, its polish, its transparency and its physical
and chemical make-up.
Brilliant Cut - This round
cut is the most common and popular style of cut for diamonds,
and many other gemstones. This is because it has been designed
with 57 carefully proportioned facets to maximise the amount
of light reflected and refracted by the gemstone. Below

It is one of the four characteristics that influence

pure gold and 250 parts other metals).

Clarity - One of the four
characteristics that influence the value of a diamond.
A diamond's clarity is determined by the degree to which
it is free from naturally occurring inclusions, or “nature's
fingerprints”. The number, type, colour, size and position
of these “birthmarks” can affect the value. However, many
of these inclusions are actually invisible to the naked
eye and require magnification under an eyeglass before
they can be seen. The fewer the inclusions, the rarer the
diamond and thus the more valuable it is.
Clasp - Any type of attachment
that is used to join one end of a piece of jewellery to

metal and when used in jewellery it is alloyed with other
