At just over four carats, the single stone diamond ring has a guide price of between €55,000 and €65,000.
“It’s a very important diamond single stone ring set with diamond shoulders in platinum with an IGI (International Gemological Institute) certificate which states the diamond is 4.02cts, H colour and VS2 clarity,” said John Weldon, who is hosting the auction early next week in Dublin.
“There are very few four-carat single diamonds around,” he told the
”You’d struggle to get one if you went into your local jewellers. Most people get one or one-and-a-half carats.”
Another notable item going under the hammer next week is a silver medal that once belonged to a prosecution lawyer involved in court trials after the 1916 Rising. The engraved Dublin Horse Show medal is made out to ‘the Hon Mr Justice Wylie,’ and is dated 1927.
William Wylie was born in Dublin but grew up in Coleraine, Co Derry. He was educated at Trinity College Dublin and called to the Irish bar in 1905.
From 1915 to 1918, he was a lieutenant in the Territorial Army, serving with the Trinity College Officer Training Corps in Dublin where he took part in the defence of the university during the 1916 Rising. He was subsequently appointed as the prosecuting officer at the trial of the leaders of the rising.
While the medal is low in weight and value, the auctioneer believes it could sell for anything because of its previous owner. “It came in as part of an estate of silver,” Mr Weldon said. “The guide price is only between €40 and €80 but if two people get stuck into it, it could go for anything.”
The auction, which marks 15 years in business for John Weldon Auctioneers in Dublin’s Temple Bar, is one of its biggest-ever catalogues, comprising of almost 600 lots.
The auctioneer previously sold a collection of Irish coinage in 2008, with the full sale grossing over €70,000.
The company also sold jewellery in 2012 which had belonged to Princess Victoria Louise of Prussia, with one of the pieces making €5,600.
The auction will take place at 2pm on Tuesday next in Dublin.
