BERYL 239

Cuts and colours

Faceted aquamarine | Certain non-standard cuts

are used on large stones to enhance brilliance. The cut

of this substantial 25.70-carat aquamarine stone is known

as a “Portuguese” cut.

Goshenite | This fine goshenite gemstone

features a modified emerald cut. It is

completely colourless, although such stones

can appear blue when photographed.

Faceted heliodor | The cutter of this

square-cushion heliodor has used a mixture

of facet styles to emphasize both its colour

and its brilliance.

Emerald | This octagonal emerald is cut with

a combination of cabochon rounding and flat

facets. It is designed to emphasize the centre

of the stone – the area with the fewest flaws.

Red beryl | This red beryl is approximately

1 carat in weight, but is still relatively large

for this very rare gemstone. It is brilliant-cut

and has only a few inclusions.

Emerald-cut aquamarine | Aquamarine

can have either blue or green colouring, as

seen in this ethereal, pale green stone with

an emerald cut.

Morganite | The delicate pink of this

morganite gem is one of the lighter shades

of the material, which usually occurs in

rose-pink to red-pink hues.
