Small size fossilised fern from Lune River, Tasmania. I thought this cute little egg I shaped deserved an unusual recycled sterling silver setting. The petrified fern is 150 million years old, dating back to when Tasmania was still part of Gondwana. These ferns are unique to Tasmania, so you will be wearing a piece of VERY old and unusual rock on your finger. The design features silver baubles referencing the fern's spore packets. This one is as Tasmanian as it gets. Size 'I'.
