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.

Tourmaline comes from the Sinhalese term "turamali" meaning 'stone of mixed colours'. As part of an isomorphous series, in which a range of chemical compositions occur in many individual crystals, they can be found in almost every colour. From pinks, reds, forest greens and blues, colourless and transparent to multi-coloured and opaque shades, making it one of Cassandra's favourite gemstones. The birthstone for October, it appears to have an affinity with the autumnal time of year, its myriad of colours resembling autumn leaves, falling in a cacophony of colour. Turn to pink tourmalines for an emblem of friendship and unconditional love, or delight in vibrant green tourmaline to harmonise your internal energies.
