[3] in 1998 it was bought by French billionaire Liliane Bettencourt (daughter of founder and main shareholder of L'Oreal) for US$18 million.

[8] D'Arros Island is located only 2.3 kilometres (1.4 mi) west of the northern part of St. Joseph Atoll, but it is a separate geographical unit, separated by 60–62 metres (197–203 ft) deep water of a 1 kilometre (0.62 mi) wide channel, which is deeper than much of the Amirantes Bank.

The land area of the island occupies 1.71 square kilometres (0.66 sq mi).

The vegetation is dominated by the native coconut palm (Cocos nucifera), and introduced horsetail beefwood (Casuarina equisetifolia) trees.

In 1965, five Seychelles fody (Foudia sechellarum) birds from Cousin Island were introduced to D'Arros and they have since increased to a population of a few hundred.
