Australian jeweller Calleija's passion for coloured diamonds and gemstones led John Calleija to create his own signature diamond cut, the Glacier, designed to maximise the play of light through the precious stone and enchant its wearer. While Calleija may be better known for setting rare coloured diamonds such as the Argyle Pink Diamond, it is the uniquely colourful rubellite that is the star of these seductive drop earrings. Rubellite is no ordinary tourmaline. A gemstone that never falters in its hue, it shines brilliantly in artificial light as much as it does in natural light. With two smooth, polished cabochon drops of deep pink rubellite clasped in white gold, these drop earrings are illuminated by a single faceted round white diamond, suspended from a white diamond pavé floral stud earring.
