I don't know Miss Lynn, From What I can find, Calcite is the key It is a form of calcium carbonate but modern corals use an argonite form of calcium carbonate Now long ago when the chemical makeup of seawater was different . Corals used the calcite form calcium carb form or something along those lines. I found this interesting. Somebody on Ebay is selling some calcite based fossilized coral that is fluoresecent under Uv lighting. The stuff was found in south Florida. No telling if the coral I have contains calcite. At least I know it's possible .
