A potentially unique diamond, which goes vivid pink when exposed to ultra violet light, has been found in South Africa.
The 13.7-carat diamond,being called the Tirisano Easter Diamond,
was recovered from the Tirisano Diamond Mine in the Ventersdorp diamond district.
Exposure to ultraviolet light causes the
diamond to turn vibrant fluorescent pink. It's not unusual for diamonds
to change colour in this way but vivid pink is one of the most rare
colours and the stone retains this hue for a period of time after UV
exposure.
Experts who have examined it so far
consider it to be unique but the exact rarity of the stone will have to
be established by a laboratory.
It is the property of mining companies Etruscan and Mountain Lake
who plan to sell it by auction to a private collector.
Les Meyer, a director of National Diamond
Marketing, said: "I have had cause to view several millions of stones
but I have never come across a diamond of this nature, which leads me
to believe that it is incredibly rare. "It is an exceptional piece due
to the vibrant pink fluorescence and it has caused excitement amongst
all who have examined it at National Diamond Marketing. Nobody can
quite believe the colour transition."
