The list of problems in the title makes this stone sound worse than it looks. The flaws are not under the table and the inclusion/poor crystal is not bad enough to stop the standard round brilliant from flashing. So this is a nice little Laurellite. Laurellite is a name I gave to a new variety of Elbaite, tourmaline, that comes from Mozambique. It is cuprian and has a reverse alexandrite color change change from purple/violet in daylight (cool) and blue/blue green in incandescent light (warm). This reverse color change is unique in the world of gemstones. I am personally surprised that I was able to get another piece of this very rare material since most of the purples from Mozambique, like the ones from Paraiba before them, are heated to product the cyan blue Paraiba or paraiba type gemstones. This unexpected surprise weighs .90 carats.
