French bow maker Jean-Luc Tauziede has fashioned an elaborately decorated cello bow with the help of a team of jewellers. The bow's frog and button incorporate rose gold and white gold, the back plate is set with 66 diamonds, and the button is adorned with an eight-point crown. Named 'Le Souverain' (the Sovereign), the bow took 300 hours to make and has been valued at 100,000 euros.
