[QUOTE="smallaxe, post: 1911975, member: 13430"]Your inclusion of the species name was very useful, and helped me find something in a research paper: [INDENT]in 1966, Vernon Brock and Ted Chamberlain of the University of Hawaii discovered a small bed of pink coral Corallium secundum, near 400 m depth off Makapuu, Oahu... In 1970 a long-term research program on precious corals began at the University of Hawaii and this led to the development of a selective harvesting system utilizing a manned submersible (Grigg et al., 1973; Figure 4). In 1973, Maui Divers of Hawaii incorporated this system and began a commercial operation of selective harvest for pink, gold, and bamboo coral which lasted until 1978. [/INDENT] The paper said they stopped in 1978 because of the high costs, and after that time, sourced their pink coral from Taiwan and Japan. That was about the time my dad was involved there. His company made the cameras, lighting and other gear on submersibles, which is how he came to know Maui Divers. So it's possible they made it for him, but he could also have picked it up in a shop in Hong Kong or Taiwan. Thanks everyone for the help. It helped me a lot in understanding this more and getting enough info to know what to search for.[/QUOTE]
