The reverse design by artist Pandora Young is an intersection of art and mathematics, and features a stylized pattern arranged according to the base-six system. Inspired by the Celtic triskele, the engraved art incorporates three clear Swarovski® crystals into our birthstone celebration of those born in February (amethyst), as represented by the gem-like Swarovski® crystal at the centre of the coin. The obverse features the effigy of Her Majesty Queen Elizabeth II by Susanna Blunt.
