In their most natural form, diamonds are –
well – quite ugly. They have no luster or shine,
 and in fact, look like nothing more than
broken glass. A diamond must be cut, and
then polished before it actually becomes a
thing of beauty.

Diamonds are cut with saws, into round
shapes. From the rounded shape, other
shapes may be cut, such as heart shapes
– but the shape is less important than the
quality of the cutting that is being done. If
the diamond is poorly cut, it will lose light,
and it will not sparkle and shine very well.
Each facet of the diamond must be
carefully cut into the geometrical shapes
that allow the diamond to sparkle and
shine, then the entire diamond is cut into
a specific shape, such as an emerald cut
or a princess cut diamond.

Once the cut is done, the diamond is put into
a dop, which resembles a cup with another
diamond – only a diamond is strong enough
to smooth the edges of another diamond.
Once the diamond has been cut and shaped,
and had the edges smoothed in the dop, it is
polished on a scaif or a diamond polishing
wheel.
