A unique green stone bracelet discovered beside ancient human remains in a Siberian cave is 'the oldest ever found' dating back around 40,000 years, say Russian experts.
The intricate modern-looking piece of polished jewellery - perhaps belonging to a prehistoric princess - was made of chlorite by the Denisovans, a long extinct early human grouping, it is believed.
The remarkable bracelet was found in the Altai Mountain range in 2008, but it is only now that pictures have emerged showing it in all its glory, including a reconstruction of how it would have looked at the time.

Experts who have spent years examining the bracelet say evidence suggests it was an exceptionally rare item of the era and likely held great significance for the wearer, reported The Siberian Times.
In addition, the level of skill and expertise required to create the piece has led to speculation that these earliest humans were more technologically advanced than previously thought, with the Denisovans seemingly more skilled than Homo sapiens or Neanderthals.
Scientists found that a hole had been drilled in part of the bracelet with such precision that it could only have been done with a high-rotation drill similar to those used today.
