Le Diamant

Le Diamant was a cruise and expedition vessel whose later operational history is documented under the Wikipedia title Ocean Diamond. The ship was one of several names used during its service life, also being known as Song of Flower, Explorer Starship, Ocean Diamond and, ultimately, Diamond XI. The Le Diamant name therefore describes a former commercial identity of the vessel rather than a currently operating cruise brand. The ship was associated with Compagnie du Ponant before ownership changed in late 2011. Compagnie du Ponant sold the vessel to investors, who transferred it to Quark Expeditions. Quark began operating the ship under the Ocean Diamond name in November 2012. Under that identity, it served the expedition-cruise market, carrying passengers to remote polar destinations and providing a platform for field-based educational and scientific activities. Ocean Diamond was positioned differently from a conventional resort cruise ship. Its role emphasized access to remote environments, expedition-style travel and interpretation of polar regions. The vessel’s programming included an Expert in Residence initiative through which scientists, polar researchers, historians and other specialists could undertake field work while traveling aboard the ship. Passengers could participate in or support aspects of this work, linking the cruise experience with environmental observation, historical research and destination education. Experts associated with the program included Jonathan Shackleton, Falcon Scott and Sue Flood. Their participation reflected the ship’s broader expedition model, in which specialist knowledge and guided exploration were part of the passenger offering. The available reference material does not establish a separate corporate entity, headquarters, founding date or independent ownership structure for Le Diamant itself; these details relate to the vessel and its successive operators rather than to a standalone consumer-goods company. The Le Diamant name ceased to be the ship’s active commercial identity when the vessel was renamed and transferred through later operating arrangements. Quark Expeditions used the Ocean Diamond name from November 2012. In August 2024, the vessel was observed beached at Aliağa, Turkey, reportedly for scrapping, after which the ship was renamed Diamond XI. This marked the end of its documented operating life as Ocean Diamond and left Le Diamant as a historical name in the vessel’s sequence of identities.

Le Diamant was one of the historical names of a cruise ship whose full service history is covered under the name Ocean Diamond. The vessel also operated under the names Song of Flower, Explorer Starship and Diamond XI, making Le Diamant part of a sequence of commercial identities rather than the name of a continuously independent cruise company. The ship was associated with Compagnie du Ponant before being sold in late 2011. The purchaser was described as a group of investors, who transferred the vessel to Quark Expeditions. Quark began operating it as Ocean Diamond in November 2012. Its expedition role placed it within the specialist cruise segment, particularly voyages to remote polar regions where passengers travel for exploration, interpretation and access to destinations that are not normally served by mainstream cruise itineraries. The Ocean Diamond operating concept included an Expert in Residence program. This program allowed scientists, polar researchers, historians and other experts to use the ship as a base for field work. Passengers were able to assist with or observe elements of the experts' activities, giving the voyage an educational and participatory dimension. Named participants included Jonathan Shackleton, Falcon Scott and Sue Flood. The program connected the vessel's commercial expedition function with scientific observation, polar history and environmental interpretation. The ship's identity changed again after its Ocean Diamond period. In August 2024, it was seen beached at Aliağa in Turkey under the name Diamond XI, reportedly for scrap. This observation indicates that the vessel's active cruise career had ended or was in the process of ending. Because the available material is centered on the vessel rather than a separately incorporated Le Diamant enterprise, no standalone founding date, executive roster, headquarters, public listing or financial history can be established for the Le Diamant name.

  Le Diamant was the former commercial identity of a cruise ship later known as Ocean Diamond. The vessel served the expedition-cruise market, carrying travelers to remote destinations and supporting guided exploration, destination interpretation and specialist-led educational activities. Its later service under other names means that the offering should be understood as a ship-based travel product rather than a standalone cruise company.
