Silver ring designed for Ozzy Osbourne and his Black Sabbath bandmates to wear at their farewell show is going up for auction

The silver jewellery piece was made in honour of the legendary Birmingham band's farewell concert in July, which took place just weeks before the frontman's death at the age of 76.

Created by 'Jagga,' a street artist who specialises in musical art, the ring features the Aston Villa badge and the year 1968, the year the heavy metal icons formed their band.

Five rings were made, with four going to Ozzy Osbourne (frontman), Tony Iommi (guitarist), Geezer Butler (bass player) and Bill Ward (drummer).

The fifth ring from the set will be sold by Hansons Auctioneers at the Derby Music, Vinyl & Film Memorabilia Auction on September 17, and is expected to make between £1,200 and £1,500.

Hansons music memorabilia expert Claire Howell told BBC News that Jagga had designed the rings for Osbourne personally to celebrate his last concert.

"Given the close timing to Ozzy's sad death just over a fortnight later, the gesture is all the more poignant," she said, and added that the auction was a "rare and unique opportunity" to buy the last remaining ring.

Jewellery was a crucial part of his 'prince of darkness' persona and style throughout his life as a rockstar and TV persona, often completing his gothic look with silver rings and chains featuring skulls and crosses.

Thousands of heavy metal fans attended Black Sabbath's Back to the Beginning show at Villa Park on July 5.

Osbourne, who is widely considered the father of heavy metal, died less than two weeks later at the age of 76.
