An auction house in Cannes, France, has sold abut 50 elephant tusks, or one tonne of ivory, breaking its previous record in terms of volume.
The entire haul was acquired by buyers from China, the world's biggest ivory market.
"In terms of volume, this is a new record for us," said Alexandre Debussy, the director of Cannes Encheres, which facilitated the sale.
"Our previous record in the spring was 920 pounds (420kg)," he added.
However, the 480,000 euros ($A719,964) raised from the auction was lower than usual, due to a 30 per cent drop in the price of ivory in recent months. A previous sale of a smaller volume raised 625,000 euros.
The fall in price is due to uncertainties in the ivory trade, notably Chinese buyers' difficulty in obtaining export licences from the European authorities.
"Tonnes of ivory are languishing in French people's attics, and we get requests all the time for it to be shifted," Debussy said.
The easing of export rules would "help the fight against poaching and save thousands of elephants", according to Debussy.
Earlier this year, the French government destroyed three tonnes of illegal ivory in a public event.
Although a global ban on the trade of ivory was introduced in 1989, limited legal sales are allowed.
The auction house will donate a percentage of the proceeds from Saturday's sale, nearly 5000 euros, to an anti-poaching organisation.
