The regal and bold Ozymandias design with its vibrant trios of facetted stones was inspired by the great poem by Shelley that he wrote soon after part of a statue of King Rameses II (Ozymandias in Greek) was found: 'My name is Ozymandias, King of Kings.' Cassandra's rings of iolites, amethyst and blue topaz lie set in bold tomb-like settings with a quartet of diamonds and outer bands that echo pillars of the Egyptian temples at Thebes.

Vitreous iolite stones appear in deep blue shades, enrapturing admirers with their strong pleochroism, an optical phenomenon that makes the gemstone appear to have different colours when observed from different angles. With these strong polarising effects at varying angles, it's said vikings harnessed the stones' powers to determine the position of the sun on overcast days.
