    if it looks like a diamond, smells like a diamond, and tastes like a diamond, it's probably a diamond.

    There could have been small pockets of air trapped on the surface, resulting in a larger volume measurement, in turn contributing to a lower density calculation. But it looks like less than 10% error from expected value, which is really good for a home setup.

    the testing was a waste of time... a lick test would be 100% conclusive and it would only take about 3 seconds
