Frida Kahlo, Diego River and their on-off love affair is legendary. Diego, like any good Mexican loved his food, so Frida would take him his lunch, beautifully prepared, everyday in a basket. I wanted to capture their story in a jewel, so I created a golden basket, with a handle across the top and I placed, carefully, set jewels inside: blue topaz, citrines and tourmalines and more.

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.
