I can't ignore a huge flawed argument/analogy which seems to be recurrent in this thread.
You can't bridge an analogy between coral retail prices and supercars! The reason a Ferrari, Bugatti, etc costs what it does is entirely due to the manufacturing techniques and, ultimately, that material selections. These automotive manufactures tailor to a luxury market segment, and because of this there may be a larger profit margin for them (sometimes - every Veyron sold is actually sold at a loss to Volkswagen) - but that's not a given! This is WAAAAY different and not applicable to the coral market - all corals originate from the same place! Of course, collection in some regions is more costly than others, but the scale of these types of differences is way out of bed to compare corals to cars.
And yes, that's the part of this thread which has bothered me the most.
