Mateo references the song written for the seminal 1939 film The Wizard of Oz with these 14kt gold Somewhere Over the Rainbow earrings, which echo the feature's technicolour palette. They're crafted in the USA with multicoloured channel-set sapphires and baguette-cut blue topaz drops, a gemstone shape that's associated with the Art Deco movement. Wear them to add an upbeat pop of colour to a variety of looks.
