There are several ways of fashioning
gems. Gem cutting and polishing is the most popular method of fashioning
gems. In Sri Lanka we have two main groups of cutting and polishing of
gems-Cabochons and Faceted gemstones
Cabochon is the oldest of the popular
modes of cutting is use in present day. Earlier times it was the
simplest way of fashioning gemstones, today it is done for
definite purposes. This cut is a dome shaped polished top, which is
made to act as a lens which will collect light rays from all around
and reflect back to the viewer's direction.
In faceting (cutting and polishing)
of all the ( Shaping the rough stone ) gemstones, so
many cutting styles in different shapes and also their
variations have been developed. Even to present day new cuts are
introduced. All these cuts depend on two basic conditions-style and
the shape. These two conditions are controlled by optical
properties related to beauty, structural properties of
gemstones and desirability for fashion and value. |
