One of Perth's top jewellers and his team have created a unique diamond to help seriously ill children and their families.
Rosendorff Jewellers' team of experts spent 2 1/2 months creating the "one-of-a-kind" diamond valued at more than $40,000 that will be auctioned at the Ronald McDonald House Ball On November 2.
Rosendorff's master diamond polisher worked under the direction of owner Craig Rosendorff to convert a 5.52-carat Argyle rough diamond into a 2.3-carat round, brilliant cut diamond.
The diamond's size pays homage to the Ronald McDonald House charity's 23rd anniversary.
"This is a very special diamond," Rosendorff diamond expert Andras Koka said. "It features 105 facets as opposed to the usual 57 facets of a round brilliant cut diamond."
Mr Koka said it was a "bespoke" piece created especially for the charity. "This is something very unique. It's got so much personality and exuberance when you see the diamond sparkle," he said.
"You can see what expertise and patience brings to life."
Rosendorff owner Craig Rosendorff said he was proud to donate the diamond because it would benefit sick children and their families.Since 1990, Ronald McDonald House Perth has accommodated the families of children being treated for cancer and other life-threatening illnesses at Princess Margaret Hospital for Children.
