A rough diamond with bizarre auditory qualities has been uncovered in a mine in Botswana.
The 4.23-carat gemstone, which was found by miners working in Jwaneng diamond mine last night, reportedly began issuing a ‘gargling’ sound shortly after it was dusted off.
It is thought the type IIa D-colour stone possesses a rare crystalline structure which responds to high winds with audible oscillations.
The De Leers Troup of Companies said several workers were treated on site for minor ear pain as a result of the high pitched noise issuing from the find.
A spokesperson said: “We have seen the growth of fancy coloured diamonds, now we look set to start a new era of musical diamonds.”
It is not known if the diamond will be cut and polished ready for auction – where it could compete with some of the most luxurious stones ever mined – or if it has been disregarded as some sort of prank.
