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.

Drinking a few cups of caffeinated coffee or tea every day may help in a small way to preserve brain power and prevent dementia, researchers reported on Monday.

People with the highest daily intake of caffeinated coffee had an 18% lower risk of developing dementia compared to those with the lowest such intake, according to a study based on responses to questionnaires by 132,000 U.S. adults spanning four decades.

The study, published in JAMA, also found that the people with the highest intake had a lower rate - by nearly 2 percentage points - of ‌self-perceived memory ‌or thinking problems compared to those with ‌the ⁠lowest intake.

Results were ‌similar with caffeinated tea, but not with decaffeinated beverages, the researchers said.

While the findings are encouraging, the study does not prove caffeine helps protect the brain, they said.

The magnitude of caffeine's effect, if any, was small, and there are other better-documented ways to protect cognitive function as people age, study leader Dr. Daniel Wang ⁠of Harvard Medical School said in a statement.

Lifestyle factors linked with lower risks of ‌dementia include physical exercise, a healthy diet ‍and adequate sleep, according to previous ‍research.

"Our study suggests that caffeinated coffee or tea consumption can ‍be one piece of that puzzle," Wang said.

The findings were most pronounced in participants who consumed two to three cups of caffeinated coffee or one to two cups of caffeinated tea daily, the researchers reported.

Those who drank caffeinated coffee also showed better performance on some objective tests of cognitive function, according to the ⁠study funded by the National Institutes of Health.

Further research is needed to validate the factors and mechanisms responsible for the findings, the researchers said.

They noted that bioactive ingredients in coffee and tea such as caffeine and polyphenols have emerged as possible factors that reduce nerve cell inflammation and damage while protecting against cognitive decline.

"We also compared people with different genetic predispositions to developing dementia and saw the same results - meaning coffee or caffeine is likely equally beneficial for people with high and low genetic risk of developing ‌dementia," study coauthor Dr. Yu Zhang of the Harvard T.H. Chan School of Public Health said in a statement.

The National Center for Wildlife (NCW) announced that the total number of wildlife animals released under its breeding and reintroduction programs for locally threatened species has exceeded 10,000 animals, an achievement reflecting the scale of the center’s sustained efforts to develop wildlife, restore ecosystems, and enhance biodiversity across various regions of the Kingdom.

The releases carried out by the center over the past years included more than 80 priority wildlife species, including reem gazelles (sand gazelles), Arabian oryx, Idmi gazelles, mountain ibex, houbara bustards, ostriches, and sandgrouse, as part of efforts aimed at supporting the recovery of natural populations of these species and enhancing their sustainability within their environmental and historical ranges, SPA reported.

CEO of NCW Dr. Mohammad Qurban noted that release operations are among the key tools for restoring ecosystems and reducing ecological imbalance, as the return of wildlife to their natural habitats contributes to protecting biodiversity and improving environmental quality, which in turn supports habitat integrity, the continuity of plant and animal components, and the enhancement of ecosystem functions over the long term.

NCW continues to implement its strategic plans to develop wildlife, protect endangered species, and enhance the efficiency of natural habitat management through expanding breeding programs, enhancing applied scientific research, building national capacities, and applying the best international practices in biodiversity management, in addition to raising environmental awareness, engaging local communities, and supporting eco-tourism, thereby contributing to achieving the objectives of the Saudi Green Initiative and Saudi Vision 2030, and the National Environment Strategy, toward thriving and sustainable wildlife, biodiversity, and ecosystems.
