SYDNEY EVAN Dolphin 14-karat gold, enamel, opal and diamond bracelet

Sydney Evan's bracelet has a stretchy, elasticated band that can be wrapped around your wrist a few times or even worn as a choker if you prefer. It's strung with an array of tonal-blue opals and a small charm featuring a pair of dolphins - one is encrusted with sparkling diamonds and a single blackened diamond, and the other is covered in enamel.
