Australian Parti-Sapphire Round 0.76ct

COMMENTS

Parti sapphires are dramatic gemstones that feature two or more colour zones – blue, yellow and sometimes green. Each one has a unique pattern of colour zoning.

Typically, a gem cutter will orient colour zones to create a uniform body colour when viewed face-up. However, in parti stones, the cutter orients the zones in the crystal to maximise contrast. As a result, the stone shows distinct colour zones from certain angles that appear to change or blend into more shades when rotated.

This unique blue/yellow parti-sapphire is very bright, well cut and eye-clean. It has not been treated in any way. It shows blue and yellow colour zones that blend and reflect forming shades of green. The cutter has selected a round brilliant cut which traditionally maximises light return and brightness; the reason why it is used so extensively for diamonds. It could have been cut into a less impressive fancy cut in order to maximise weight retention, however, I am personally glad this was not the case as the result is a very bright stone with loads of colour and personality.

This gem would be lovely as the hero stone in a special ring or a pendant, with or without accent stones, for example in a halo design.

DURABILITY

Sapphire’s high hardness – 9 on Mohs scale – and its excellent durability render it ideal for most types of jewellery settings.
