LONDON — A Jane Austen museum said Monday that it has received 100,000 pounds ($155,000) from an anonymous benefactor to help it buy the writer’s ring back from singer Kelly Clarkson.
Earlier this month, the British government placed a temporary export ban on the gold-and-turquoise ring in the hope that money could be found to keep it in Britain.
The Jane Austen’s House museum said it had raised 103,200 pounds of the 152,450-pound ($236,000) asking price since launching a fund-raising campaign on Friday, most of it from a single anonymous donation.
‘‘We are two-thirds of the way there in 48 hours, which is tremendous, but we’re not there yet,’’ said museum fund-raiser Louise West.
The author of ‘‘Pride and Prejudice,’’ who died in 1817 at 41, left the ring to her sister Cassandra. It remained in the family until it was sold at a Sotheby’s auction last year.
The museum at Austen’s former home in Chawton, southern England, had hoped to buy the ring last year but was outbid when it sold for five times the estimated price.
Clarkson — an Austen fan who owns a first edition of the author’s novel ‘‘Persuasion’’ — was the successful buyer. But she has been prevented from taking the ring home to the United States by a power that allows the British government to temporarily halt the export of works judged to be national treasures.
The museum has until December to raise the rest of the money, and Clarkson has agreed to sell the ring should a buyer come forward.
West said the situation is a shame for Clarkson, ‘‘but the ring should stay in this country, because there is so little of Austen’s personal effects left.’’
West said the museum had invited the 2002 ‘‘American Idol’’ winner to come visit the next time she is in Britain. She said Clarkson’s interest in the author was another sign that Austen’s popularity remains strong, 200 years after she published her most famous novel, ‘‘Pride and Prejudice.’’
‘‘It is very good for Jane Austen PR that a young, famous American pop star expresses a love for her,’’ West said.
