Further than 700 particulars collected by late Austrian art collector Heidi Horten on show before anticipated£ 120m charity transaction in Geneva

The world’s most precious private jewellery collection will go on display in London from Saturday before what's anticipated to be a record- breaking£ 120m charity transaction.

The further than 700 particulars of jewellery collected by the late Austrian billionaire art collector Heidi Horten is on a world stint, taking in New York, Singapore, Taipei and London, in the run- up to a four- part transaction at Christie’s in Geneva coming month and online. Some of the top pieces will be on public display at its St James ’ transaction room in central London from Saturday until Wednesday.

The collection includes a white gold and diamond Cartier ring set with the Sunrise Ruby, the world’s most preciousnon-diamond rock, which Horten bought for$30.4 m(£24.5 m) at transaction eight times agone
. The25.59- carat rare “ chump’s blood ” Myanmar ruby is described by the Swiss Gemmological Institute as a “ unique treasure of nature ” and is anticipated to vend for$ 15m-$ 20m.

Also over for transaction are the Briolette of India, a90.38- carat colourless diamond cut by the jeweller Harry Winston and a three- beachfront natural plum choker with an 11- carat pink diamond grasp estimated to vend for$ 7m to$ 10m.

In total the collection is anticipated to cost further than$ 150m(£ 120m), making it the most precious set of jewels ever vended at transaction – surpassing the$ 116m Elizabeth Taylor’s vended for in 2011 and the$ 109m trade of the Qatar’s ruling Al Thani family’s in 2019.

Rahul Kadakia, Christie’s transnational head of jewellery, described Horten’s treasures as “ the collection of a continuance ”.

“ From Bulgari to Van Cleef & Arpels, from a small particular memory piece to the Briolette of India, this is a collector’s dream, ” he said.

Horten – who inherited an estimated£2.7 bn when her hubby, the department store mogul Helmut Horten, failed in 1987 – failed in June 2022 with no direct heirs at law.

Enterprises have been raised about the source of the family fortune, including allegations that Helmut Horten acquired means from Jewish people who had had their property sequestered by the Nazis.

A Horten collection commissioned report by chroniclers at the University of Würzburg set up he “ advantaged from the profitable circumstances handed by the Nazi state. He did not, still, take active way to ply pressure on the Jewish merchandisers. ”

All the proceeds from the Christie’s trade will go to the Heidi Horten Foundation, which she set up in 2020 to fund a public art gallery in Vienna to hold her vast art collection and to fund medical exploration.

Horten failed just days after opening the Heidi Horten Collection gallery, which includes pieces by Francis Bacon, Gustav Klimt, Damien Hirst, Egon Schiele and Pablo Picasso.

A keen ice skater in her youth, Horten was a lifelong ice hockey addict and supported the Austrian platoon EC- KAC to which she reportedly bestowed€ 3m(£2.7 m) a time. The platoon has named its new colosseum after her.
