A diamond-studded necklace thought to be involved in a scandal that led to the eventual downfall of the last queen of France, Marie Antoinette, is being sold in Geneva next week.
The Georgian-era piece containing 300 carats of diamonds being sold by a Asian private collector in Geneva on Nov. 13 is valued at around 2 million Swiss francs ($2.29 million), Sotheby's said, although it may fetch much more.
The piece was at the center of a scandal in the 1780s known as the 'Diamond Necklace Affair' in which a hard-up noblewoman named Jeanne de la Motte pretended to be the French queen and acquired the necklace in her name without payment
A subsequent trial found the queen blameless, yet did little to alleviate her growing notoriety for extravagance which helped fuel the French Revolution and Marie Antoinette's beheading.
"It's likely or possible that some of these diamonds may have come from the famous diamond necklace that led to the downfall of Marie Antoinette," Jessica Wyndham, head of magnificent jewels sales for Sotheby's, told Reuters on Thursday.
"What we've seen is that jewelry with a noble provenance can generate a huge amount of excitement," she added, citing a pearl pendant belonging to the French queen which the auction house sold in 2018 for many times its initial estimate.
The diamonds of the original piece, crafted in 1776, were later sold piecemeal on the black market so are almost impossible to trace. However, some experts say the quality and age of the diamonds point to a match.
The necklace, which resembles a neck scarf, can be worn open or knotted at the front. One of its previous owners was Britain's Marquess of Anglesey and a family member wore it on the occasion of Queen Elizabeth II's coronation, according to Sotheby's.
"I think it's one of the most exciting pieces that we've had for a long time, not only with the provenance, but the design," said Wyndham.

EU Monitor: 2024 'Virtually Certain' to Be Hottest Year on Record

This year is "virtually certain" to be the hottest in recorded history with warming above 1.5C, EU climate monitor Copernicus said Thursday, days before nations are due to gather for crunch UN climate talks.
The European agency said the world was passing a "new milestone" of temperature records that should serve to accelerate action to cut planet-heating emissions at the UN negotiations in Azerbaijan next week, AFP said.
Last month, marked by deadly flooding in Spain and Hurricane Milton in the United States, was the second hottest October on record, with average global temperatures second only to the same period in 2023.
Copernicus said 2024 would likely be more than 1.55 degrees Celsius above the 1850-1900 average -- the period before the industrial-scale burning of fossil fuels.
This does not amount to a breach of the Paris deal, which strives to limit global warming to below 2C and preferably 1.5C, because that is measured over decades and not individual years.
"It is now virtually certain that 2024 will be the warmest year on record and the first year of more than 1.5C above pre-industrial levels," said Copernicus Climate Change Service (C3S) Deputy Director Samantha Burgess.
"This marks a new milestone in global temperature records and should serve as a catalyst to raise ambition for the upcoming Climate Change Conference, COP29."
Wild weather
The UN climate negotiations in Azerbaijan, which will set the stage for a new round of crucial carbon-cutting targets, will take place in the wake of the United States election victory by Donald Trump.
Trump, a climate change denier, pulled the US out of the Paris Agreement during his first presidency -- and while his successor Joe Biden took the United States back in, he has threatened to do so again.
Meanwhile, average global temperatures have reached new peaks, as have concentrations of planet-heating gases in the atmosphere.
Scientists say the safer 1.5C limit is rapidly slipping out of reach, while stressing that every tenth of a degree of temperature rise heralds progressively more damaging impacts.
Last month the UN said the current pace of climate action would result in a catastrophic 3.1C of warming this century, while all current climate pledges taken in full would still amount to a devastating 2.6C temperature rise.
Global warming is not just about rising temperatures, but the knock-on effect of all the extra heat in the atmosphere and seas.
Warmer air can hold more water vapor, and warmer oceans mean greater evaporation, resulting in more intense downpours and storms.
In a month of weather extremes, October saw above-average rainfall across swathes of Europe, as well as parts of China, the US, Brazil and Australia, Copernicus said.
The US is also experiencing ongoing drought, which affected record numbers of people, the EU monitor added.
Copernicus said average sea surface temperatures in the area it monitors were the second highest on record for the month of October.
C3S uses billions of measurements from satellites, ships, aircraft and weather stations to aid its calculations.
Copernicus records go back to 1940 but other sources of climate data such as ice cores, tree rings and coral skeletons allow scientists to expand their conclusions using evidence from much deeper in the past.
Climate scientists say the period being lived through right now is likely the warmest the earth has been for the last 100,000 years, back at the start of the last Ice Ages.
